8 ideas
We distinguish ambiguities by seeing what is useful [Sext.Empiricus]
     Full Idea: It is the experience of what is useful in each affair that brings about the distinguishing of ambiguities.
     From: Sextus Empiricus (Outlines of Pyrrhonism [c.180], II.258)
Instead of seeking Truth, we should seek belief that is beyond doubt [Peirce]
     Full Idea: Your problems would be greatly simplified, if, instead of saying that you want to know the Truth, you were simply to say that you want to attain a state of belief unassailable beyond doubt.
     From: Charles Sanders Peirce (Essentials of Pragmatism [1905], I)
     A reaction: This is not the same as saying that belief beyond doubt IS truth. He is merely offering a strategy for scientists to side-step the sort of scepticism raised by Descartes and radical empiricists.
Pragmatism is a way of establishing meanings, not a theory of metaphysics or a set of truths [Peirce]
     Full Idea: Pragmatism is no doctrine of metaphysics, no attempt to determine the truth of things. It is merely a method of ascertaining the meanings of hard words and of abstract concepts.
     From: Charles Sanders Peirce (Pragmatism in Retrospect [1906], p.271)
     A reaction: Suddenly I recognise a prominent strand of modern philosophy of language (especially in America) for what it is.
Pragmatism accepts any hypothesis which has useful consequences [James]
     Full Idea: On pragmatic principles we cannot reject any hypothesis if consequences useful to life flow from it.
     From: William James (Pragmatism - eight lectures [1907], Lec 8)
     A reaction: Most governments seem to find lies more useful than the truth. Maybe most children are better off not knowing the truth about their parents. It might be disastrous to know the truth about what other people are thinking. Is 'useful but false' meaningful?
Pragmatism judges by effects, but I judge truth by causes [Russell]
     Full Idea: Pragmatism holds that a belief is to be judged if it has certain effects, whereas I hold that an empirical belief is to be judged true if it has certain kinds of causes.
     From: Bertrand Russell (My Philosophical Development [1959], Ch.15)
     A reaction: I'm with Russell here, and this seems to me a convincing objection to pragmatism. The simple problem is that falsehoods can occasionally have very beneficial effects. Beliefs are made true by the facts, not by their consequences.
New linguistic claims about entities are not true or false, but just expedient, fruitful or successful [Carnap]
     Full Idea: The acceptance of new linguistic forms about entities cannot be judged as being either true or false because it is not an assertion. It can only be judged as being more or less expedient, fruitful, conducive to the aim for which the language is intended.
     From: Rudolph Carnap (Empiricism, Semantics and Ontology [1950], 3)
     A reaction: The obvious problem seems to be that a complete pack of lies might be successful for a very long time, if it plugged a critical hole in a major theory. Is success judged financially? How do we judge success without mentioning truth?
Pragmatism is the worst idea ever [Fodor]
     Full Idea: Pragmatism is perhaps the worst idea that philosophy ever had.
     From: Jerry A. Fodor (LOT 2 [2008], Ch.1)
     A reaction: Not an argument, but an interesting sign of the times. Most major modern American philosophers, such as Quine, seem to fit some loose label of 'pragmatist'. I always smell a feeble relativism, and a refusal to face the interesting questions.
Pragmatism is better understood as a theory of belief than as a theory of truth [Engel]
     Full Idea: Pragmatism in general is better construed as a certain conception of belief, rather than as a distinctive conception of truth.
     From: Pascal Engel (Truth [2002], §1.5)
     A reaction: Which is why aspiring relativists drift towards the pragmatic theory - because they want to dispense with truth (and hence knowledge), and put mere belief in its place.
