So here's that quote: """ The mathematical problems of what is called foundations are no more the foundation of mathematics for us than the painted rock is the support of a painted tower. """ pg. 378 Here are some other tidbits... My task is, not to talk about (e.g.) Gödel's proof, but to by-pass it. (pg 383) However queer it sounds, my task as far as concerns Gödel's proof seems merely to consist in making clear what such a proposition as: "Suppose this could be proved" means in mathematics. (pg. 388-89) One does not learn to obey a rule by first learning the use of the word "agreement". Rather, one learns the meaning of "agreement" by learning to follow a rule. (pg 405) We say: "If you really follow the rule in multiplying, you must all get the same result." Now if this is only the somewhat hysterical way of putting things that you get in university talk, it need not interest us overmuch. It is however the expression of an attitude towards the technique of calculation, which comes out everywhere in our life. The emphasis of the *must* corresponds only to the inexorableness of this attitude both to the technique of calculating and to a host of related techniques. The mathematical Must is only another expression of the fact that mathematics forms concepts. And concepts help us to comprehend things. They correspond to a particular way of dealing with situations. (pg 431) -- compare with investigation of "inexorable" on pg. 82 Here's that all import "machine analogy" (comparing to rule following, the inexorability of logic): """ If we know the machine, everything else, that is its movement, seems to be already completely determined. "We talk as if these parts could only move in this way, as if they could not do anything else." How is this--do we forget the possibility of their bending, breaking off, melting, and so on? Yes; in many cases we don't think of that at all. We use a machine, or the picture of a machine, to symbolize a particular action of the machine. For instance, we give someone such a picture and assume that he will derive the movement of the parts from it. (Just as we can give someone a number by telling him that it is the twenty-fifth in the series 1, 4, 9, 16, ....) "The machine's action seems to be in it from the start" means: you are inclined to compare the future movements of the machine in definiteness to objects which are already lying in a drawer and which we then take out. But we do not say this kind of thing when we are concerned with predicting the actual behavior of a machine. Here we do not in general forget the possibility of a distortion of the parts and so on. We do talk like that, however, when we are wondering at the way we can use a machine to symbolize a given way of moving -- since it can also move in quite different ways. Now, we might say that a machine, or the picture of it, is the first of a series of pictures which we have learned to derive from this one. But when we remember that the machine could also have moved differently, it readily seems to us as if the way it moves must be contained in the machine-as-symbol far more determinately than in the actual machine. As if it were not enough here for the movements in question to be empirically determined in advance, but they had to be really--in a mysterious sense--already present. And it is quite true: the movement of the machine-as-symbol is predetermined in a different sense from that in which the movement of any given actual machine is predetermined. """ Kirby
