Summary

Wittgenstein argues that ethics can never be a science because language can only meaningfully describe empirical facts, whereas moral judgments require an absolute, normative dimension that transcends physical reality and resides in the inexpressible.

By defining the logical limits of language, this perspective protects ethical life from being reduced to empirical science or instrumental utility, framing morality instead as an existential orientation toward the absolute.

Section summaries

0:00-1:03

Introduction to the Lecture on Ethics

watch

The presenter introduces Ludwig Wittgenstein's *Lecture on Ethics*, a short but profound talk delivered to a non-philosophical audience in Cambridge. This lecture showcases Wittgenstein as an accessible, humorous pedagogue. Chronologically, the text sits exactly between his two major masterpieces: the *Tractatus Logico-Philosophicus* and the *Philosophical Investigations*, capturing a crucial transitional period in his views on language.

  • The Lecture on Ethics represents a unique, highly pedagogical moment in Wittgenstein's teaching career.
  • The text is situated at the precise historical and conceptual pivot point between his early and late philosophy.

It sets the historical and stylistic context for Wittgenstein's ethical inquiry.

1:03-5:15

Linguistic Boundaries and the Early Tractatus Framework

watch

This section summarizes the core ideas of the *Tractatus*, showing how Wittgenstein ties the meaning of propositions directly to empirical verification in the physical world. Any statements concerning metaphysics, the spiritual, or aesthetics are classified as logical 'nonsense' because they cannot point to verifiable facts. By restricting meaningful language to the depiction of facts, Wittgenstein originally claimed to have solved all fundamental philosophical errors by silencing abstract metaphysical debates.

  • In early analytic philosophy, a statement only has sense if it corresponds directly to a physical fact in the world.
  • Metaphysical, religious, and aesthetic claims are labeled 'nonsense' because they point to no empirical referents.
  • Wittgenstein's early work concluded with the famous demand to remain silent on things that transcend empirical language.

It lays down the necessary linguistic rules needed to grasp why ethics is unspeakable under his system.

5:15-9:27

Bridging Wittgenstein to David Hume's Guillotine

watch

The presenter addresses how Wittgenstein breaks his own rule of silence to talk about ethics, which does not exist as a physical fact in the world. To set up Wittgenstein's analysis, the presenter introduces David Hume's famous moral theory from the *Treatise of Human Nature*. This introduces Hume's Guillotine, which critiques the imperceptible slide in moral texts from descriptive assertions about the world to prescriptive commands about what people should do.

  • Morality is not an empirical phenomenon; no one has ever observed a physical fact called 'morality' directly in nature.
  • Hume's Guillotine is a logical boundary separating statements of fact from statements of obligation.
  • Wittgenstein's work acts as a direct modern continuation of the British empiricist tradition regarding ethics.

It introduces Hume's Guillotine, which is vital to understanding the logical separation of facts and values.

9:27-16:48

Deconstructing Hume's Law and the Role of Sentiment

optional

The presenter dispels common misunderstandings of Hume's Guillotine, clarifying that it is not merely a critique of the appeal to nature. He demonstrates how moral statements are often falsely framed as descriptions (such as claiming lying is inherently immoral) when they are actually pre-packaged value judgments. Ultimately, Hume resolves the gap between facts and values by grounding moral imperatives in human sentiment, empathy, and feelings rather than cold rational calculation.

  • Hume's Guillotine strictly targets the logical fallacy of deriving an 'ought' from an 'is'.
  • A descriptive fact of physics or physiology (e.g., how a life is taken) can never contain the moral command 'thou shalt not kill'.
  • Ethics, for Hume, is built entirely upon human sentiment, utility, and emotions rather than scientific observation.

It is a highly valuable clarification of Hume's philosophy, but functions mostly as an external detour.

16:48-22:03

Relative vs. Absolute Values: Tennis and Lies

watch

The video returns to Wittgenstein's text to explain his distinction between relative and absolute value. Using Wittgenstein's examples, the presenter contrasts a bad tennis player (whose poor performance is a relative, non-moral issue of skill) with a deceptive liar (whose actions receive an absolute, moral demand that they *must* want to behave better). Relative values are shown to be easily translatable into simple statements of objective fact, whereas absolute moral values stubbornly resist this reduction.

  • Relative values are conditional, depending entirely on a pre-existing goal (e.g., taking the correct road to a specific destination).
  • Absolute values are unconditional demands that apply to actions regardless of an individual's goals or desires.
  • No objective description of a physical fact can ever contain or logically imply an absolute judgment of value.

This is the core conceptual distinction of Wittgenstein's Lecture on Ethics.

22:03-27:18

The Self-Justification of Absolute Ethics

watch

The presenter explains how absolute ethical judgments require the moral quality of an action to reside strictly within the action itself, independent of external outcomes. This separates ethics entirely from instrumental, descriptive knowledge. To illustrate this, the presenter references Friedrich Nietzsche's claim in *Beyond Good and Evil* that there are no moral phenomena, but only moral interpretations of phenomena, aligning the continental critique with Wittgenstein's linguistic analysis.

  • In absolute ethics, the end cannot justify the means because the moral quality of the action is judged unconditionally.
  • Both Wittgenstein and Nietzsche suggest that nature is empty of intrinsic moral values, leaving only human interpretation.
  • Ethical language fails to communicate empirical truths, making it technically 'nonsense' from a purely logical perspective.

Provides a crucial bridge to Nietzschean philosophy, highly relevant to viewers of continental thought.

27:18-33:36

The Grand Book of the World and the Flatness of Facts

watch

The presenter details Wittgenstein's thought experiment of the 'Grand Book of the World'. If an omniscient being compiled a book containing every physical and psychological fact in history, it would contain absolutely zero moral declarations. A murder, meticulously documented down to the physical trajectory of the knife and the psychological states of the actors, would sit on the same factual plane as a stone falling from a cliff. Our emotional horror is a psychological fact, but not an ethical proof.

  • An exhaustive list of scientific facts would never yield a single moral truth or ethical value.
  • In a purely empirical worldview, all natural events—from a falling stone to a murder—are logically leveled.
  • Feelings of indignation, anger, and horror are facts in themselves, but they do not make the event factually 'evil'.

It clearly demonstrates why ethics cannot be structured as an empirical science.

33:36-35:42

The Teacup Metaphor: Pushing the Limits of Language

watch

This section unpacks Wittgenstein's metaphor of the teacup. Our words are natural vessels meant to carry natural meaning, and trying to fill them with absolute, supernatural values is like attempting to pour a liter of water into a single teacup; it simply overflows. No matter how emotionally intense we make our vocabulary to describe an atrocity or a saintly act, the language overflows, failing to convey anything beyond factual description.

  • Human language is structurally designed to describe the natural world and cannot contain 'supernatural' absolute values.
  • Expanding our vocabulary or screaming our indignation does not alter the factual limits of descriptive speech.
  • Absolute ethics is 'supernatural' and cannot be systematically formalized within logical language.

Explains one of the most famous and illustrative metaphors in Wittgenstein's work.

35:42-40:57

The Mystical Cage and the Noble Human Impulse

watch

The presenter concludes the video by focusing on Wittgenstein's profound respect for the mystical impulse. Wittgenstein argues that although our attempts to speak of the absolute, the ultimate meaning of life, or the miracle of existence are logically hopeless, they represent a noble, universal human drive. Pushing against the walls of our linguistic cage does not increase our scientific knowledge, but it documents a deeply respectable tendency in the human spirit that must never be ridiculed.

  • The very existence of language is the closest we can get to experiencing the miracle of the world's existence.
  • Pushing against the boundaries of language is a hopeless but defining and noble human activity.
  • Wittgenstein does not dismiss ethics; he places it in the realm of the ineffable, which must be felt rather than spoken.

Provides the crucial existential and respectful resolution of Wittgenstein's philosophy.

Key points

  • Hume's Guillotine and the Is-Ought Fallacy — David Hume's law states that one cannot logically deduce a prescriptive, normative statement of what 'ought' to be from a purely descriptive statement of what 'is'.
  • Relative vs. Absolute Values — Relative values represent instrumental suitability for a specific, predetermined end (e.g., a 'good' tennis player), whereas absolute values demand unconditional moral compliance regardless of personal goals (e.g., not being a liar).
  • The Grand Book of the World Thought Experiment — An omniscient book detailing every physical and psychological fact in the universe would contain no ethical judgments; a brutal murder would sit on the exact same factual plane as a falling stone.
  • The Teacup of Language and the Mystical Impulse — Our language is a natural vessel designed to hold natural facts (like a teacup holding water); attempting to load it with absolute, supernatural ethical meaning inevitably results in logical nonsense.

Hello everyone and welcome to this

0:02

new recording dedicated to

0:06

Vidgenstein's thought. Today I wanted to

0:08

talk to you about a short text by

0:09

Vidgenstein called "A Lecture on

0:13

Ethics." Small in size, but large in

0:16

content and scope. To

0:19

briefly situate the "A Lecture on

0:21

Ethics," it's a lecture given

0:23

by Vidgenstein in Cambridge to a lay audience with

0:26

no particular philosophical curiosity.

0:29

We discover in it a

0:32

pedagogical side of Vidgenstein, who uses

0:35

many examples, some of which are

0:37

funny and sometimes even

0:38

wacky. In short, in this text, the author of the

0:42

Tractatus adopts a

0:44

refreshingly teacherly stance and makes

0:47

his ethical thought as intelligible as possible.

0:52

This lecture can be situated precisely between the

0:54

writing of Vidgenstein's two major works,

0:58

the Tractatus Logico-

1:01

Philosophicus and the

1:05

Philosophical Investigations. This distinction is

1:07

important because while the Tractatus addressed

1:10

the limits of language, the

1:13

Philosophical Investigations, which his mentor Russell

1:15

considered uninteresting,

1:18

focused more on the social and

1:20

practical character of language, showing that This recording

1:23

obviously cannot be limited

1:26

to a strictly descriptive function.

1:30

I've already dedicated a recording to

1:33

each of the two works; in fact, it

1:35

seems the one on the Tractatus

1:38

is one of the most popular on my

1:39

channel because I elaborate on the

1:42

main ideas of the Tractatus at length.

1:44

So, if you're interested, you can take a look.

1:47

I won't go over it again in this

1:49

recording, but I'll simply recall

1:51

some basics of his thought at the beginning

1:54

when I deem it necessary. My

1:57

goal here is to make Witgenstein as

2:00

accessible as possible because I know he

2:02

can sometimes be off-putting and frightening

2:05

to those who aren't yet very

2:07

philosophically trained, and I think

2:10

his lecture on ethics is a good

2:12

way to achieve this. Why am I emphasizing

2:16

the publication date of this

2:18

lecture? Precisely because

2:21

Witgenstein develops, one might

2:23

say, the practical consequences of the

2:26

limitations of language that he

2:28

previously outlined in his Tractatus.

2:30

I'll give a few quick reminders about his

2:33

thought for those who aren't very familiar with

2:35

Witgenstein. Please don't hold it against me

2:37

if I simplify things a bit.

2:39

Here, as I've already said, I'm discussing the

2:42

Tractatus in more detail

2:44

elsewhere. Widgenstein was a student of

2:46

Russell and belongs to the school of thought known as

2:49

analytic philosophy, a school that

2:52

seeks to decompose the structure of our

2:54

language in order to reveal the

2:57

errors we make

2:59

when, like some

3:01

metaphysical philosophers, we speak without saying anything.

3:04

In the Tractatus, Widgenstein

3:07

pushed this perspective to its

3:09

limits, showing that if the

3:12

only sensible use of language consists of

3:15

perfectly encompassing all the

3:18

facts that constitute our world,

3:23

then most of our propositions are nonsense. Indeed,

3:26

Widgenstein's logic is a logic that makes the

3:30

meaning of our propositions dependent on

3:33

our

3:34

experience based on

3:37

observation. If, in language,

3:39

I express something spiritual,

3:42

metaphysical,

3:44

or even something related to

3:47

aesthetic experience—"Wow, this

3:50

piece of music is so beautiful!"—I am expressing something

3:52

that, by definition, is

3:55

inexpressible because the words I use

3:57

correspond

4:00

to elements of reality that they serve

4:02

to

4:03

designate. But the world, composed of facts, shows

4:07

the totality of facts. According to

4:10

Witgenstein, about whom I can say something, nothing can

4:13

be placed on the same level

4:15

as what is experienced

4:17

internally, particularly when I

4:20

observe the limits of my language in

4:22

trying to express what Witgenstein

4:25

calls the mystical, the feeling of something

4:28

beyond language. I have something expressible

4:31

that coincides with the limits of my

4:33

world, since I can say nothing about the

4:36

world except what appears to me in it.

4:38

Many of our propositions are

4:41

philosophical nonsense, especially in

4:44

the religious domain, which I will

4:46

return to later. It is in this that

4:48

Witgenstein claimed to solve

4:51

philosophical problems, since he

4:53

thus provided a criterion for establishing

4:56

which propositions still have meaning and which do

4:59

not, and to undermine

5:01

metaphysical theses employing

5:04

abstract terms referring to a reality that

5:07

escapes the sum of facts that

5:08

constitute our world—a good or a

5:11

beautiful in itself, God, and so on. I'm making it

5:16

brief, but here, essentially, Witgenstein

5:18

concludes his Tractatus by saying that one

5:20

should remain silent about what

5:23

one He cannot speak of the silence he deigns to

5:25

break, since his lecture on

5:27

ethics concerns the domain of

5:29

morality, which

5:32

at first glance does not seem to fall within the realm of fact. Indeed, no

5:36

one has ever seen morality

5:38

incarnate; one would have to be

5:40

very presumptuous to think oneself to be

5:42

morality incarnate, to be a fact,

5:45

a moral phenomenon, except perhaps

5:49

the disciples of Jesus, and even then, according to

5:51

them, no one has ever seen

5:54

morality incarnate, which would be a matter of fact.

5:56

We have all undoubtedly

5:58

seen people who are examples

6:01

of kindness and virtue, or

6:04

conversely, of wickedness or vice. But

6:06

precisely by designating these people as such,

6:10

we have judged them.

6:13

All value in matters of morality

6:15

consists of establishing a judgment

6:17

based on certain criteria. But

6:21

are these criteria absolute and

6:24

indisputable? Can we establish a

6:26

science of good and evil in the same way

6:29

that we try to establish criteria in science or

6:32

epistemology to

6:35

distinguish truth from falsehood? It is on

6:38

this point that we will now examine, starting from

6:40

The limits of the

6:43

language Widgenstein developed and

6:45

the ethical consequences he

6:48

will address in this

6:50

lecture are discussed, but first, I'll take a

6:53

brief detour to David Yum, whom I've

6:56

mentioned a few times and whose moral

6:59

theory I recently explored. There's

7:01

a major text by Yum

7:06

in his Treatise of

7:07

Human Nature, Book 3, dedicated to morality,

7:10

which I haven't discussed until now,

7:13

but which resonates with

7:14

Widgenstein's

7:16

ethical thesis. Mind you, I'm not saying that

7:19

Humum and Widgenstein say the same

7:20

thing, even though

7:23

Humum's influence on the latter is evident. It would be

7:25

disingenuous to

7:27

tell me there's no connection between the

7:28

two ideas. Widgenstein, being in

7:31

the lineage of the

7:33

empiricist tradition, is simply being shown to have

7:35

a clear link between them on this very

7:38

point, and that Yum sheds some

7:42

light on

7:44

what Widgenstein will say. In

7:48

any case, we'll see how this takes on even greater significance.

7:50

So, going back to

7:52

Yum, this is the excerpt where

7:55

the famous Law of Yum appears,

8:00

sometimes also called Yum's Guillotine. We're going to talk

8:03

about Yum's Guillotine because,

8:05

wow, it's impressive, it's striking! Well, actually,

8:08

Yum's Law is pretty cool

8:09

too, you might say.

8:12

Anyway, Yum's Guillotine is

8:14

n't easy to grasp at all, to the point

8:17

that when you try to illustrate it, you run into a brick wall.

8:19

Misunderstandings

8:21

surface everywhere as soon as you

8:23

try to understand concretely

8:26

what it consists of, and obviously, I won't name names.

8:30

I'm going to read you the excerpt in question

8:32

and tell you what, in my opinion, is the

8:34

valid interpretation of this idea in

8:37

practice. So, I quote: "I can't help but

8:40

add to these arguments

8:42

an observation that may be

8:44

of some importance in all the

8:47

moral systems I've encountered so far:

8:49

I've always noticed that

8:51

the author proceeds for a while with the

8:54

ordinary way of reasoning and

8:58

establishes the existence of a God." or makes

9:00

observations concerning

9:02

human affairs when suddenly I am astonished to

9:05

find that instead of encountering the

9:07

usual copulas "and" and "is not," I

9:10

find no proposition that is not

9:13

connected with fingers or "should not."

9:16

This change is imperceptible but

9:18

nevertheless has great consequences because,

9:21

as "should" or "should not" expresses

9:23

some new relation or

9:26

affirmation, it is necessary that

9:28

this be observed and explained, and that at the

9:31

same time a reason be given

9:33

for those things that seem quite

9:34

inconceivable: that this relation could

9:36

be a deduction from others that are

9:39

entirely different. But since

9:42

authors do not frequently use

9:43

this precaution, I take the liberty of

9:45

recommending it to the reader, and I am

9:48

convinced that this small attention will cause

9:50

all vulgar systems of

9:53

morality to succumb and will show us that the

9:56

distinction between vice and virtue is

9:58

not based simply on the

10:00

relation between objects, nor is it perceived by

10:03

reason. End of quote. The idea of ​​"yum"

10:07

is very simple to summarize but

10:08

incredibly difficult to explain,

10:11

especially when it comes to taking

10:13

concrete examples. The idea fits in one

10:15

sentence: one cannot You can't deduce

10:18

normative principles from

10:22

descriptive statements, or put it another way: you can't go from a

10:25

being to an ought-to-be.

10:28

The term "

10:30

guillotine" is used to name this

10:33

idea, which amounts to cutting or slicing

10:37

between statements linked

10:40

to facts observed through simple

10:43

observation—what is, and what ought to

10:46

be, or should be.

10:48

So, imagine a

10:51

proposition with a stated value

10:54

concerning what is—that's the body—and the

10:56

subsequent statement indicating a duty—that's

11:00

the head. Well, smack! The

11:02

guillotine arrives in the middle and slices

11:04

the statement in two, saying no. What

11:08

comes before has nothing to do with what comes

11:09

after. In fact, I think that's why we

11:11

talk about the

11:12

guillotine. But it's still not

11:15

clear. Concretely, what does it mean?

11:17

Because it's all very abstract. Let's

11:19

cut the ground out from under you, but without a

11:21

guillotine or a lawnmower, there's a very common misconception

11:24

when it comes to

11:25

explaining this. The first

11:27

misinterpretation is to think that *Humum*

11:30

criticizes the fallacy

11:32

commonly known as the "call of nature," essentially implying that

11:35

if something is natural, it must be

11:37

good, and we should follow nature, which

11:39

tells us what is right to do. You

11:42

can disregard this interpretation,

11:44

given that *Humum* doesn't mention

11:47

nature and, in the

11:48

excerpt I quoted, doesn't discuss anything other than

11:51

propositions related to

11:53

theological questions concerning God

11:56

or what he calls "

11:58

human affairs"—in other words, matters of

12:00

our everyday behavior,

12:02

ethics, or morality. The other

12:06

misinterpretation would be to say that *

12:08

Humum*'s law doesn't allow for

12:11

moral judgments or the establishment of

12:14

duties based on observations

12:17

without this being false. In reality, if I acknowledge from

12:24

the outset that I'm making a moral argument and

12:26

state the premises in a normal way,

12:30

the proposition in question is valid.

12:32

For example, using *

12:34

Humum*'s guillotine, one could say that the

12:36

proposition Lying is an action that

12:39

should never be carried out because it is

12:43

essential to preserve a society founded

12:46

on trust in our

12:48

mutual exchanges. There is no contradiction because

12:51

in the first part of my sentence

12:53

I use the word "should" and I link this

12:56

duty to an imperative related to trust.

13:00

Basically, we shouldn't lie to each other because we

13:03

must be able to trust each other. The

13:06

guillotine of "yum" doesn't cut anything at all.

13:08

However, if I say the

13:11

following: "It is immoral to lie," or

13:15

rather, "Lying is wrong, therefore we must

13:18

n't lie," it works much

13:21

less well. In fact, the very proposition "

13:23

It is immoral to lie" already results

13:27

from a judgment, so it's a

13:29

prescription that passes for a

13:31

descriptive statement. In fact, I'm acting as if

13:34

the action itself

13:37

were objectively immoral, or that lying

13:40

was something immoral, but in

13:42

reality, it's already a judgment. So the

13:45

initial proposition would be: "Lying

13:48

consists of hiding the truth from someone

13:50

by telling them something false;

13:53

therefore, it is immoral and must not be

13:56

done." Well, there, the "guoti chlac" (a French expression meaning "the wording")

14:00

comes into play in my previous sentence.

14:02

I'm thus making the leap from the descriptive

14:05

to the

14:07

normative. When I say that

14:11

lying consists of this, I describe very

14:13

precisely what it consists of, and

14:15

then I say, "and therefore we mustn't lie." There, I

14:17

go

14:33

from "that's how it is," to "that's what

14:37

it consists of," and therefore "we mustn't do it." And yes, well, why shouldn't we do it? Well, we shouldn't. We're troubled because it's not something we can justify based on a fact. Yes, lying consists of

14:40

deceiving someone. Yes, and so what

14:42

prevents me from doing so? So, we ca

14:44

n't base morality on a fact; we can't

14:47

go from a fact to a duty.

14:50

You see, that's something that seems

14:52

implacable, but it's also

14:56

logical because, as

14:58

I explained,

14:59

if everything is normative in the proposition,

15:03

well, in that case it's fine, but in

15:05

any case, we mustn't... Moving from the

15:07

descriptive to the

15:08

normative—basically, Youum's idea is that something

15:11

stated indicatively cannot give rise

15:14

to

15:16

a prescription or a duty. And if You

15:19

says this, it's also because

15:21

morality isn't simply a matter of

15:23

observation but of feeling. We can't

15:27

arrive at the imperative "Thou shalt not kill"

15:30

simply by first reminding ourselves

15:32

that killing consists of taking

15:35

someone's life. We must feel in our

15:38

own flesh that someone is

15:40

profoundly evil. It's not the

15:42

act of recalling what murder is

15:44

that will lead us to morality and

15:46

duties, according to Youum. But I've

15:50

already elaborated on this elsewhere recently. We can't

15:52

invoke mere observation

15:54

to establish morality or ethics because the latter

15:56

will necessarily rest

15:59

on feelings of justice or

16:01

injustice, which, in turn, will

16:04

dictate what is useful or harmful for

16:07

ourselves and others, and therefore good

16:10

or evil. I refer you to

16:12

the recording in question for more

16:13

details on this point. This is also the

16:16

reason why Yum brings

16:19

reason into play at the end of the extreme I quoted

16:21

just before concerning morality,

16:23

since it depends on feelings.

16:26

Morality is not a matter of prior calculation;

16:29

reason, as we know, strictly allows for

16:31

calculation. But now let's

16:34

return to Widgenstein, because we will be able to

16:36

observe that his theory about

16:39

ethics resonates with

16:41

Yum's law and allows us to precisely circumscribe the

16:45

field of ethics.

16:47

Widgenstein begins by

16:50

considering that defining ethics

16:53

based on the field that studies what constitutes

16:55

good in a moral sense remains imprecise,

16:59

in the sense that the term "good" can take on

17:02

different meanings depending on the

17:04

situation and what one actually wants to say.

17:07

Widgenstein therefore begins

17:09

by making a distinction between a

17:12

relative meaning—understood as relative to a

17:15

specific goal or a predetermined end,

17:18

which would not fall within the field of

17:20

ethics—and an absolute meaning, which, on the other hand,

17:24

would depend on ethics. When

17:27

I say that something is good, I can mean that it is

17:30

adequate to the goal I am aiming for.

17:32

But I don't

17:34

necessarily mean by that that it's

17:36

virtuous and that it falls under the umbrella of morality.

17:38

Why would morality fall under what

17:40

Widgenstein calls an absolute sense? And what do we mean

17:43

by that? That's what we're going to

17:46

see now with two

17:48

very relevant and illuminating examples: the bad

17:51

tennis player and the lying cad. The lying cad

17:55

isn't my example, it could have been,

17:58

but this is a

18:00

Widgenstein example.

18:02

Yes, I assure you that the example of the lying cad

18:04

is excellent. You'll see. I

18:06

quote him like this: instead of saying ethics is the

18:10

investigation of what is good, I could have

18:13

said what is

18:14

the investigation of what has value

18:17

or what really matters? Or I could have

18:19

said that ethics

18:21

is the investigation of the meaning of life or

18:23

what really matters? Or I could have

18:26

said that ethics is the

18:27

investigation of the meaning of life or

18:30

what makes life worth living

18:32

or the correct way to live. I

18:35

think that by examining all these sentences

18:38

you will get a rough idea

18:40

of ​​what ethics deals with. Now, the

18:43

first thing that strikes us in

18:46

all these expressions is that each

18:48

of them is actually used in two

18:50

very different senses. I will call them, on the

18:53

one hand, the trivial or relative sense, and on the other hand,

18:56

the ethical or AB sense. For

18:59

example, if I say, "Here's a good

19:02

chair," it means that this chair

19:04

serves a certain predetermined purpose, and the

19:09

word "good" that we use here only has

19:11

meaning insofar as

19:13

this purpose is already pre-established. In fact, the

19:17

word "good" in the relative sense

19:19

simply means that which satisfies a certain

19:23

predetermined model. Thus, when we say of

19:25

someone that he is a good pianist, we

19:28

mean by that that he can play

19:30

music of a certain degree of difficulty

19:33

with a certain degree of

19:36

dexterity. And similarly, if I say that it is

19:38

important for me not to catch a cold, I

19:41

mean by that that a cold

19:44

produces certain disturbances in my life

19:45

that can be

19:47

described. And if I say that this is the By "

19:50

correct route," I mean

19:52

the correct route to reach

19:54

a certain goal. Used in this way,

19:57

these expressions don't raise any

19:59

difficulties or serious problems, but

20:02

that's not how ethics

20:04

uses them. Suppose I knew how to

20:08

play tennis, and one of you,

20:10

seeing me play, said, "You play badly,"

20:13

and I replied, "I know I

20:16

play badly, but I don't want to play better."

20:20

All my interlocutor could

20:22

say would be, "Oh, well, in that case, everything's fine."

20:24

But suppose I told

20:27

one of you an

20:29

extravagant lie, and they came to me and said, "You

20:32

behave like a Gou," and I replied, "

20:35

I know I behave badly, but

20:38

anyway, I don't want to behave any better."

20:41

Could they then say, "Oh,

20:46

well, in that case, everything's fine"?

20:49

Certainly not. They would say, "Well, you

20:52

must want to behave better." Here

20:55

you have an absolute value judgment,

20:57

whereas the one in the

20:59

previous example was a relative judgment in

21:01

its essence. The difference between these two

21:04

types of judgment seems clearly to

21:06

consist in this: every value judgment A

21:09

relative value judgment is a simple statement of fact and

21:12

can therefore be formulated in

21:15

such a way that it loses all appearance

21:18

of value judgment. Instead of saying, "This is

21:21

the correct route to

21:23

Grandchester," I could just as easily say, "This is

21:25

the correct route you need to

21:28

learn if you want to get to

21:30

Grandchester in the

21:32

shortest possible time." "This man is a good runner" simply

21:35

means that he covers

21:38

a certain number of kilometers in a

21:40

certain number of minutes, and so on. What

21:42

I want to argue now, although it

21:45

can be shown that any

21:46

relative value judgment reduces to a simple

21:49

statement of fact, is that no statement of

21:52

fact can be, or can imply,

21:54

an absolute value judgment. End of

21:56

quote. To

22:00

summarize, when one states a

22:02

relative judgment outside the realm of ethics,

22:05

it is always justified

22:07

beforehand by a specific end,

22:11

and this end becomes the very condition

22:13

of the action: "I will take this path

22:17

because I know it is the condition for

22:19

reaching my destination," or, as

22:22

absurd as it may seem, "If I

22:24

want to play bad tennis," or "I

22:27

absolutely must not..." improved, so

22:30

I have to keep hitting

22:31

my ball haphazardly with My racket, yes, who are

22:34

you to force Vidgenstein to

22:36

take tennis lessons, huh? If he

22:38

wants to play badly, well, he plays badly, huh?

22:40

He's not hurting anyone by

22:42

randomly hitting the

22:44

ball with his racket, at least not as long as he doesn't

22:48

accidentally send the ball into the

22:49

sensitive areas of passersby, which

22:53

his example doesn't mention, by the way. Let's give him the benefit of the doubt that he's probably not

23:00

hurting anyone. However, if he

23:02

behaves like a lying, boorish man and makes

23:05

his interlocutors believe false

23:07

things about himself to make himself look good, like he

23:10

was a kind

23:12

and affectionate teacher towards

23:14

his students, for example, well, in that

23:17

case, if he's caught out by people

23:20

who feel deceived by his lie,

23:23

he can't just

23:25

justify himself by admitting his desire to be

23:27

a lying jerk and expect

23:30

his

23:31

interlocutor's approval. Being a bad

23:34

tennis player is one thing, if that's what that he

23:36

wants, but lying so brazenly

23:39

can only lead to disapproval because

23:42

the action induces a judgment from the other

23:44

person. All is not well

23:47

in the sense that the lying jerk should question himself

23:50

and stop

23:53

taking people for fools by

23:56

appropriating efforts and merits

23:58

that are

23:59

foreign to him. The judgment is said to have

24:02

absolute value because it is the action that is judged

24:05

morally by the action in relation to

24:09

a

24:10

goal. In other words, the

24:14

absolute value of the action is linked to the fact that

24:16

nothing external to the action itself

24:19

can legitimize

24:21

or

24:23

justify it. The end does not justify the

24:26

means because ethics judges

24:29

the action as absolutely good or bad without any

24:31

reference other than

24:33

a value of good

24:37

or evil whose claim is

24:39

universal. Therefore, it is not the action

24:42

relative to a goal that is judged, but

24:44

truly the action as such,

24:47

not in relation to anything other than itself. This is

24:49

the

24:51

absolute dimension that we find precisely in From an ethical standpoint,

24:53

it is absolutely wrong to

24:56

behave like a lying cad, and this is

24:59

not justifiable in relation to the end the lying

25:02

cad sets for himself. However, if

25:05

we adopt the perspective of

25:08

relative judgment, which is not that of ethics,

25:10

we can call the lying cad's lie

25:13

successful if no one manages to

25:16

unmask him. His lie is good because it

25:19

is credible and convincing in order to deceive those around him. As

25:22

you will have

25:24

understood, we come back to the

25:26

major philosophical problem that Yum

25:29

indirectly raised: if

25:32

knowledge is based on

25:33

observations of facts, and if this

25:36

empirical teaching allows us to know

25:38

what to do to obtain a certain

25:41

result, then morality escapes the

25:43

realm of knowledge. It possesses

25:46

a prescriptive dimension that cannot

25:49

be deduced from the realm of simple

25:51

observation, giving rise to

25:54

descriptive statements. In this sense, it is possible

25:58

that the lying cad might give a lesson,

26:02

and in front of him, someone might give

26:05

him a moral lesson, and who might

26:08

reply, "It's not moral, certainly, but

26:10

I must lie in order to get by." For what

26:14

I am not and to achieve my goal, in

26:17

other words, the description of a

26:19

set of conditions to be met to

26:21

achieve a goal, and foreign to morality,

26:23

which is concerned with absolute values ​​that are unobservable,

26:28

and since they are unobservable,

26:30

they can only be nonsense

26:32

from a logical point of view because there are no

26:35

moral facts, or as

26:37

a certain Nietzsche would say in Beyond

26:40

Good and Evil, there are no

26:43

moral phenomena, only a moral interpretation

26:45

of phenomena. I can proclaim my

26:48

indignation, say that it is good or bad,

26:50

but I will never manage to state

26:53

a proposition that makes as much sense

26:56

to my interlocutor as, for example, "there is a

26:58

desk in front of me" or "it is raining

27:01

outside," because these elements

27:04

correspond to verifiable facts at

27:06

any moment. My language then

27:09

conforms to a part of the world.

27:12

Wittgenstein explains this point well with

27:14

another pedagogical example

27:17

that can be likened to a

27:19

thought experiment that one generally known

27:21

as the great book of the world, I

27:24

quote, let me explain it thus:

27:28

suppose that one of you is

27:30

omniscient and therefore

27:32

knows of all the movements of

27:34

all bodies, dead or living, in this

27:36

world; that you also know

27:38

all the states of mind of all

27:41

human beings at whatever time

27:43

they lived; and that everything you know is written down

27:45

in a large book.

27:48

This book would contain the

27:49

complete description of the world. And the point I want to make is that

27:52

this book would

27:54

contain nothing that we would call

27:56

an ethical judgment, nor anything that would

27:59

logically imply such a

28:01

judgment. Naturally, it would contain

28:04

all judgments of relative value,

28:06

all true scientific propositions,

28:08

and in fact all

28:11

true propositions that can be

28:12

formulated. But all written facts would be, in a

28:15

way, on the same level,

28:17

and likewise all propositions would be on the

28:19

same level. There are no

28:22

propositions that, in any absolute sense,

28:25

be sublime, important, or trivial. End of

28:30

quote. So, one must imagine an

28:32

immense book that would

28:34

ultimately contain, according to the The very definition of the

28:37

world in the

28:38

Tractatus is the totality of facts, since, as

28:41

I recall at the beginning of the Tractatus,

28:43

Vidgenstein defines the world thus:

28:46

imagine that someone could access at

28:49

any moment everything that

28:51

constitutes the world in which we

28:53

live, the sum total of the facts that occur there

28:55

and which remain the basis for

28:58

any meaningful statement, since they

29:00

possess a real reference point. Well,

29:04

in that case, even if we had the

29:06

omniscient gaze of a kind of God, even if we had

29:09

total and

29:10

complete knowledge of the world, we still wouldn't know what

29:13

ethics are. We would know

29:15

that such and such a physical law is linked to such and such a

29:17

process, stated scientifically

29:20

and rigorously. We would know that such and such a

29:22

person once thought or acted in such

29:25

and such a way by observing their actions, but nothing

29:28

moral would be taught to us.

29:31

We could describe with as much

29:33

precision as possible the state of the

29:35

world and the way inert,

29:39

living, or human bodies act and

29:41

interact, but that's all. We would never

29:44

leave the realm of

29:47

description, and nothing would

29:49

allow us to pronounce

29:51

judgments with moral value. But yet,

29:54

if We can observe the state of the world and

29:56

everything that happens in it; we would certainly be able

29:59

to witness the horrors that

30:01

take place. Isn't this a

30:04

decisive experience for establishing

30:06

morality and for arriving at the

30:08

factual observation of things that are

30:10

morally good or bad? Well, no, not quite.

30:14

And that's where we see that with

30:17

this, the guillotine of

30:20

Yum would always be sufficiently

30:22

sharp if V. Gstein were to use it. And he

30:25

will illustrate this with the example of

30:28

murder. I quote: what I mean is that a state

30:30

of mind, insofar as

30:33

we understand by this expression

30:35

a fact that we can describe, is neither

30:38

good nor bad in an ethical sense.

30:41

For example, if we read in our

30:44

book of the world the description of a

30:46

murder with all its physical

30:48

and psychological details, the pure description of

30:50

these facts will contain nothing that we

30:53

could call an

30:54

ethical proposition. The murder will be exactly on the

30:57

same level as any other

30:59

event, for example, the falling of a

31:01

stone. Certainly, reading this

31:04

description could provoke pain in us.

31:06

Anger or any other

31:08

emotion, or we could read about

31:11

the pain or anger that this

31:12

murder aroused in those who learned of it,

31:15

but there will

31:17

only be facts, facts, facts,

31:20

but not ethics. Therefore, I must

31:24

say that if I were to consider what

31:26

ethics should truly be,

31:29

assuming such a science exists, the

31:32

result seems quite obvious to me.

31:34

End of quote. This example is very

31:37

illuminating insofar as it

31:38

reminds us at the same time of the limits of

31:41

language and shows us its full

31:43

extent concerning ethics. Indeed, even when

31:46

trying to penetrate the inner thoughts of the

31:48

murderer, even when describing the

31:51

motivation behind the murder, the

31:53

precise way in which it takes place, it is still

31:56

nothing that falls within the domain of

31:59

ethics; it is description.

32:02

Here, we describe that A killed B out of a thirst for

32:06

revenge and that B stabbed him

32:07

countless times with a large

32:10

knife, for example, in order to satisfy

32:12

his bloodlust as

32:15

intensely as possible. In saying this, I have

32:18

still not stated any

32:20

moral judgment, nothing that is ethical.

32:23

Obviously, one can... To feel disgusted by

32:26

the description of the murder, to feel within oneself

32:28

the greatest indignation,

32:31

to have a sense of horror or

32:33

terror in the face of the cold and

32:35

relative judgment aimed at establishing as

32:38

accurately as possible the

32:40

circumstances of the crime and the

32:42

exact motives of the criminal—yet still,

32:45

no ethics

32:48

intervenes in this story. As you will have

32:50

understood, Widgenstein's great thesis

32:52

is here as simple as it is

32:55

profound: ethics relating to the notion of

32:58

good or evil does not pertain to

33:00

science or established truth, but to

33:03

the unspeakable. I could shout my

33:05

indignation and say, "It's horrible, what happened

33:08

is appalling, it's

33:10

very wrong," but I would say nothing true, nothing real.

33:14

Strange as it

33:17

may seem, put that way, moreover,

33:19

all our language seems to deny this.

33:22

When we

33:24

sometimes say, "It's really horrible" or "What

33:28

you did is really wrong," we

33:30

say "really," we say "really," as if that,

33:33

precisely, gives an

33:36

even more real dimension to the judgment, to what is

33:38

the object of the judgment. You see, but

33:40

precisely, we give a The

33:43

actual content of the order of facts, expressed in words that in

33:46

no way reflect the facts of this

33:48

world and the structure of reality,

33:51

therefore ethics rests on nonsense.

33:54

Hence the following passage from Widgenstein

33:57

describes the supernatural dimension of

34:00

ethics: our words, as we

34:03

use them in science, are vessels

34:05

capable only of containing and

34:07

transmitting meaning and sense,

34:10

meaning and natural sense. Ethics,

34:14

if it exists, is supernatural, whereas

34:16

our words only want to express

34:19

facts, like a cup of tea that will never

34:21

contain more water than the value

34:24

of a cup, even if I pour

34:26

a liter of water into it. I said that

34:29

insofar as it concerns facts of

34:31

propositions, there is only relative value, relative

34:33

accuracy, end of

34:38

quote. The metaphor of the cup of tea

34:40

means that it can never

34:43

contain more than the quantity of water

34:45

it is designed to hold, and that, just like

34:48

this cup, we may

34:51

try to exceed the

34:53

limits of our language, as one

34:56

overflows the cup, try to

34:59

fill it to The use of words, even

35:02

stronger and more meaningful than possible, to

35:04

morally blame or honor a set

35:07

of actions performed by someone, will

35:10

never allow us to go beyond the

35:13

limits of description. The cup won't

35:18

suddenly hold more water

35:20

because I decided to put in more than it

35:22

can hold; it

35:24

will simply overflow. And it's the same for my

35:26

language. My pledge won't suddenly start

35:29

expressing

35:31

more than I can

35:34

accurately describe under

35:35

normal circumstances. But Vidgenstein goes further,

35:38

showing that the same is true

35:40

for any mystical or

35:43

religious experience. Here we are in the presence

35:45

of the unspeakable, of what remains buried deep

35:48

within us and cannot be

35:50

expressed using words whose referent is not

35:53

in the world; it is not there. And

35:57

so, it is never a matter

36:00

of observation or science; it is what

36:03

we also feel in the face of the fact that there is

36:06

something rather than nothing, something

36:09

which was not lacking in To be astonished, as

36:11

Heugger or, before him, Emnitz noted,

36:14

sometimes without thinking about it, we find ourselves astonished by

36:16

the existence

36:19

of this world in which we live,

36:21

particularly when we contemplate the

36:23

beauty of natural landscapes while

36:25

walking. I quote Wigstein again, and

36:29

I will now describe the experience

36:31

of being astonished by the existence of the

36:33

world by saying that it is the experience of

36:35

seeing the world as a miracle. I am

36:38

then tempted to say that the

36:40

correct way to express in language the

36:42

miracle of the world's existence, although it is

36:44

not a proposition of

36:46

language, is the existence of language

36:48

itself. But what then does it mean that

36:51

we become aware of this miracle at

36:53

certain times and not at others? Because

36:55

all I have done in shifting the

36:57

expression of the miraculous from an

36:59

expression through the means of language to an

37:02

expression through the existence of language,

37:04

all I have done is to

37:07

say again that we cannot express what

37:10

we want to express, and all

37:12

we say about the Miraculous absolute remains

37:14

nonsense. End of quote. Here, Wittgenstein

37:20

implicitly reminds us that the limits of

37:22

our world coincide with those of our

37:24

language, because we cannot say that

37:27

anything has meaning outside the

37:30

horizon of our common experience of

37:32

observable facts. Yet it is in

37:35

language that we can think and say

37:37

this. The existence of language

37:40

then appears as a kind of miracle, and the

37:42

fact of being able to pronounce on the

37:44

limits of our knowledge, or of what

37:46

we cannot express as knowledge, is also a miracle.

37:49

However, in doing so,

37:52

we are still expressing nonsense, because

37:54

nothing absolute can, by definition,

37:57

be relative. Here, it is relative to an

38:00

external element that serves as its reference and

38:03

that it serves to designate. Therefore, what

38:05

remains absolute, as opposed to relative, appears to be

38:08

nonsense. What

38:11

appears as an intimate experience

38:14

linked to anything observable has as its

38:17

reference only a feeling, something

38:19

that cannot be the subject of a

38:21

rigorously objective description because

38:24

it does not concern a physical fact.

38:26

Hence, Wittgenstein's conclusion—I

38:29

quote everything to which I I tended, and I

38:33

believe, to what all men

38:35

who have ever tried to write or

38:37

speak about ethics or religion tend to do was to

38:39

confront the limits of

38:41

language. It is perfectly, absolutely hopeless to

38:44

thus confront

38:47

the walls of our cage, insofar as

38:50

ethics is born from the desire to say

38:52

something about the ultimate meaning

38:55

of life, about absolute Good, about that which

38:58

has absolute value. Ethics

39:00

cannot be a science; what it says

39:03

adds nothing to our knowledge in any

39:06

sense, but it informs us about a

39:08

tendency that exists in the

39:11

human mind, a tendency that I can only

39:13

deeply respect, and

39:16

that I could never, in my life,

39:18

ridicule. End of quote. This last

39:21

point is fundamental because it allows us

39:24

not to misunderstand Wittgenstein's intentions. He is not

39:28

saying that since we cannot

39:30

describe what morality is, or what

39:33

good and evil are, they do not exist,

39:35

or that no morality is possible.

39:38

Rather, Wittgenstein shows here that there is no way

39:41

Language will never be able to

39:44

guide us towards good or help us

39:47

discover it; no

39:50

ethical or philosophical system can do so in a

39:52

meaningful way, because these are

39:55

necessarily metaphysical statements that

39:57

elevate us to something mystical,

40:00

going far beyond language. We sense

40:03

good or evil; we can feel it

40:06

viscerally when we are

40:09

confronted with facts, but these facts do

40:12

not possess the moral properties we

40:14

attribute to them in judgment. Ethics does not

40:17

lead us to a better

40:18

understanding of the world or ourselves;

40:20

it does not allow us to go beyond what can be

40:22

expressed, in that it expresses

40:25

no

40:26

meaning. But it reveals to us, in a

40:28

profound way, that we cannot help but

40:30

try to transcend the

40:32

limits imposed by our language. In

40:36

short, the necessity we have to

40:38

judge as good or evil, which

40:41

appears to us, is the mark of our

40:43

inability to see language as merely a

40:46

medium at the service of

40:48

knowledge, a simple tool of

40:50

communication intended for

40:54

utilitarian information and related to mere survival.

40:58

We have within us this need for the absolute and That's precisely what

41:01

an analysis of the limits

41:03

of language reveals:

41:08

good and evil remain

41:10

unknown, yet they will forever haunt

41:13

us, drawing us into

41:15

the unknown, into an ineffable realm we

41:18

cannot

41:19

express. Thank you for your

41:21

attention, and I'll see you next

41:24

time.
