Philosophy aims at what is interesting, remarkable or important - not at knowledge or truth [Deleuze/Guattari]
|
|
Full Idea:
Philosophy does not consist in knowing, and is not inspired by truth. Rather, it is categories like Interesting, Remarkable, or Important that determine success or failure.
|
|
From:
G Deleuze / F Guattari (What is Philosophy? [1991], 1.3)
|
|
A reaction:
Speak for yourself. I wonder what the criteria are for 'Interesting' or 'Important'. They can't seriously count 'remarkable' as a criterion of philosophical success, can they? There can be remarkable stupidity.

Philosophers have given precise senses to deduction, probability, computability etc [Quine/Ullian]
|
|
Full Idea:
Successful explications (giving a precise sense to a term) have been found for the concepts of deduction, probability and computability, to name just three.
|
|
From:
W Quine / J Ullian (The Web of Belief [1970], 65), quoted by Alex Orenstein - W.V. Quine Ch.3
|
|
A reaction:
Quine also cites the concept of an 'ordered pair'. Orenstein adds Tarski's definition of truth, Russell's definite descriptions, and the explication of existence in terms of quantifications. Cf. Idea 2958.

The plague of philosophy is those who criticise without creating, and defend dead concepts [Deleuze/Guattari]
|
|
Full Idea:
Those who criticise without creating, those who are content to defend the vanished concept without being able to give it the forces it needs to return to life, are the plague of philosophy.
|
|
From:
G Deleuze / F Guattari (What is Philosophy? [1991], 1.1)
|
|
A reaction:
This seems to be the continental view of analytical philosophy, that it is pathetically conservative. I would offer MacIntyre as a response, who gives a beautiful analysis of why the super-modern view is dead. The French are hopelessly romantic.

'Eris' is the divinity of conflict, the opposite of Philia, the god of friendship [Deleuze/Guattari]
|
|
Full Idea:
'Eris' is the Greek divinity of discord, conflict, and strife, the complementary opposite of Philia, the divinity of union and friendship.
|
|
From:
G Deleuze / F Guattari (What is Philosophy? [1991], 1.2 n)
|
|
A reaction:
Are these actual gods? This interestingly implies that the wonders of dialectic and Socrates' elenchus are simply aspects of friendship, which was elevated by Epicurus to the highest good. The Greeks just wanted wonderful friends and fine speeches.

ZFC could contain a contradiction, and it can never prove its own consistency [MacLane]
|
|
Full Idea:
We have at hand no proof that the axioms of ZFC for set theory will never yield a contradiction, while Gödel's second theorem tells us that such a consistency proof cannot be conducted within ZFC.
|
|
From:
Saunders MacLane (Mathematics: Form and Function [1986], p.406), quoted by Penelope Maddy - Naturalism in Mathematics
|
|
A reaction:
Maddy quotes this, while defending set theory as the foundation of mathematics, but it clearly isn't the most secure foundation that could be devised. She says the benefits of set theory do not need guaranteed consistency (p.30).

Concepts are superior because they make us more aware, and change our thinking [Deleuze/Guattari]
|
|
Full Idea:
If one concept is 'better' than an earlier one, it is because it makes us aware of new variations and unknown resonances, it carries out unforeseen cuttings-out, it brings forth an Event that surveys (survole) us.
|
|
From:
G Deleuze / F Guattari (What is Philosophy? [1991], 1.1)
|
|
A reaction:
I don't get much of that, but it is certainly in tune with the Kuhn/Feyerabend idea that what science can generate is fresh visions, rather than precisely expanded truths. Personally I consider it dangerous nonsense, but I thought I ought to pass it on.

Phenomenology says thought is part of the world [Deleuze/Guattari]
|
|
Full Idea:
According to phenomenology, thought depends on man's relations with the world - with which the brain is necessarily in agreement because it is drawn from these relations.
|
|
From:
G Deleuze / F Guattari (What is Philosophy? [1991], Conclusion)
|
|
A reaction:
The development of externalist views of mind, arising from the Twin Earth idea, seems to provide a link to continental philosophy, where similar ideas are found in Husserl, Sartre and Merleau-Ponty. So study science, psychology, or sociology?

The logical attitude tries to turn concepts into functions, when they are really forms or forces [Deleuze/Guattari]
|
|
Full Idea:
Logic is reductionist not accidentally, but essentially and necessarily: following the route marked out by Frege and Russell, it wants to turn the concept into a function (...when actually a concept is a form, or a force).
|
|
From:
G Deleuze / F Guattari (What is Philosophy? [1991], 2.6)
|
|
A reaction:
[Last part on p.144] I'm not sure that I understand 'form or force', but the idea that concepts are mere functions is like describing something as 'transport', without saying whether it is bus/bike/train.. Is a concept a vision, or a tool?
