__Weyl:__All musicians agree that underlying the emotional element of music is a strong formal element. It may be that it is capable of some such mathematical treatment as has proved successful for the art of ornaments. If so, we have probably not yet discovered the appropriate mathematical tools. .... Andreas Speiser ... has taken a special interest in the group-theoretic aspects of ornaments [and] tried to apply combinatorial principles of a mathematical nature ... to the formal problems of music [in hisTheorie der Gruppen von endlicher Ordnung[1924], chapter entitled "Die mathematische Denkweise"]

If nature were all lawfulness then every phenomenon would share the full symmetry of the universal laws of nature .... The mere fact that this is not so proves thatcontingencyis an essential feature of the world.

__Hardy:__[T]here is no scorn more profound, or on the whole more justifiable, than that of the men who make for the men who explain. Exposition, criticism, appreciation, is work for second-rate minds. (p.61)

What we do may be small, but it has a certain character of permanence; and to have produced anything of the slightest permanent interest, whether it be a copy of verses or a geometrical theorem, is to have done something utterly beyond the powers of the vast majority of men. (p.76)

We must guard against the fallacy common among apologists of science, the fallacy of supposing that the men whose work most benefits humanity are thinking much of that while they do it, that physiologists, for example, have particularly noble souls. A physiologist may indeed be glad to remember that his work will benefit mankind, but the motives which provide the force and the inspiration for it are indistinguishable from those of a classical scholar or a mathematician. (p.?)

[I]f a mathematician, or a chemist, or even a physiologist, were to tell me that the driving force in his work had been the desire to benefit humanity, then I should not believe him (nor should I think the better of him if I did). (p.79)

A mathematician, like a painter or a poet, is a maker of patterns. If his patterns are more permanent than theirs, it is because they are made withideas. (p.84)

[I have to quibble with him here & in the following quote. The patterns of the poet and painter are made up of ideas no less than those of the mathematician.]

The mathematician's patterns, like the painter's or the poet's, must bebeautiful; the ideas, like the colors or the words, must fit together in a harmonious way. Beauty is the first test: there is no place in the world for ugly mathematics. (p.85)

The best mathematics isseriousas well as beautiful – 'important' if you like, but the word is very ambiguous, and 'serious' expresses what I mean much better. (p.89)

[V]ery little of mathematics is useful practically, and ... that little is comparatively dull. The 'seriousness' of a mathematical theorem lies, not in its practical consequences, which are usually negligible, but in thesignificanceof the mathematical ideas which it connects. We may say, roughly, that a mathematical idea is 'significant' if it can be connected, in a natural and illuminating way, with a large complex of other mathematical ideas. Thus a serious mathematical theorem, a theorem which connects significant ideas, is likely to lead to important advances in mathematics itself and even in other sciences. (p.89)

There are two things at any rate which seem essential [in a 'significant' idea], a certaingeneralityand a certaindepth.... (p.103)

*A Mathematician's Apology*

*

Doing vs. using. It is not necessary to "do" mathematics in order to "use" it (this is different than the usual distinction of abstract vs. applied). And the same in the sciences – physics, medicine, anthropology, genetics, chemistry. What's not often evident is how widely this distinction can apply. In music too often the performer is only "using" music, not "doing" it. That's why too much musical practice is like acrobatics: there's no doubt the performance is masterful, but someone else inventd the tricks."Doing" need not involve creation, but at the very least it includes a drive to understanding the creation. In musical performance this involves the need to impart this drive to someone called "the audience."

Many people think reality is prosaic. I don't. We don't explain things away .... We get closer to the mystery.

__Plato__I do not, however, think the attempt to tell mankind of these matters a good thing, except in the case of some few who are capable of discovering the truth for themselves with a little guidance. In the case of the rest to do so would excite in some an unjustified contempt in a thoroughly offensive fashion, in others certain lofty and vain hopes, as if they had acquired some awesome lore.
