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
