Don't think, but look! (PI 66)

Our craving for generality has [as one] source … our preoccupation with the method of science. I mean the method of reducing the explanation of natural phenomena to the smallest possible number of primitive natural laws; and, in mathematics, of unifying the treatment of different topics by using a generalization. Philosophers constantly see the method of science before their eyes, and are irresistibly tempted to ask and answer in the way science does. This tendency is the real source of metaphysics, and leads the philosopher into complete darkness. I want to say here that it can never be our job to reduce anything to anything, or to explain anything. Philosophy really is “purely descriptive.

An honest religious thinker is like a tightrope walker. He almost looks as though he were walking on nothing but air. His support is the slenderest imaginable. And yet it really is possible to walk on it.

This is all that “ordinary” in the phrase “ordinary language philosophy” means, or ought to mean. It does not refer to particular words of wide use, nor to particular sorts of men. It reminds us that whatever words are said and meant are said and meant by particular men, and that to understand what they (the words) mean you must understand what they (whoever is using them) means, and that sometimes men, do not see what they mean, that usually they cannot say what they mean, that for various reasons they may not know what they mean, and that when they are forced to recognize this they feel they do not, and perhaps cannot, mean anything, and they are struck dumb.

What is the proof that I know something? Most certainly not my saying I know it.

But doesn't it come out here that knowledge is related to a decision?
