:02:01
Words don't matter.
:02:03
Your students can follow you
in that kind of thinking?
:02:05
They follow and even lead.
:02:07
Dad, can you help me?
:02:10
Lead?
:02:11
For example...
:02:14
...with five or six students, I started...
:02:16
...a maieutic dialogue,
like in Plato's Theaetus.
:02:20
Is science perception?
Do we see through our eyes or with them?
:02:24
While I didn't want to get too involved...
:02:27
...we found ourselves questioning...
:02:29
...the possibility
of synthetic a priori judgments...
:02:32
...Iike in the Critique of Pure Reason.
:02:37
You were saying, your students....
:02:39
Question the possibility
of synthetic a priori judgments!
:02:42
Yes, anyway....
:02:44
Do you know what a synthetic
a priori judgment is?
:02:47
If I knew, I forgot. And you?
:02:49
Yes. A synthetic a priori judgment...
:02:51
...is one that, while a priori,
is not analytical.
:02:57
To be more precise, excuse the jargon...
:03:00
...it's a judgment in which the predicate
isn't inherent in the subject.
:03:04
For example?
:03:07
Let's use Kant's example.
:03:08
"All bodies are extended in space,"
is an analytical judgment.
:03:11
But "All bodies are heavy,"
is a synthetic judgment...
:03:14
...but a posteriori,
because the idea of weight...
:03:17
...is not contained in the subject idea,
but validated by experience.
:03:21
And "synthetic a priori"?
:03:27
"All bodies are...."
What example does Kant use?
:03:30
Kant's example is: "Everything
that happens has a cause."
:03:33
We can also use mathematical
propositions. When I say:
:03:36
"A straight line is the shortest path
between two points,"...
:03:40
...it doesn't stem from the concept
of straightness nor from experience.
:03:43
Yes, because space is an a priori form
of perception.
:03:47
Bravo!
:03:48
You didn't forget a thing!
:03:50
-You learned that, at least?
-I told you, no.
:03:53
Maybe it was discussed,
but I wasn't there, or I wasn't listening.
:03:57
That didn't stop me from getting an "A".
