"There is no logical way to the discovery of these elementary laws. There is only the way of intuition . . . The longing to behold [cosmic] harmony is the source of the inexhaustible patience and perseverance . . . The state of mind that enables a man to do work of this kind is akin to that of the religious worshiper or the lover; the daily effort comes from no deliberate intention or program, but straight from the heart." -- Albert Einstein, quoted in Lifting the Veil, the Feminine Face of Science, Linda Jean Shepherd, 1993, p. 215.
"I remember perfectly well the intense satisfaction and delight with which I had listened, by the hour, to Bach's fugues . . . and it has often occurred to me that the pleasure derived from musical compositions of this kind . . . is exactly the same as in most of my [scientific research on] problems of morphology -- that you have the theme in one of the old masters' works followed out in all its endless variations, always reappearing and always reminding you of the unity in variety." -- Thomas Huxley, 1895, quoted in Developmental Biology, second edition, Scott F. Gilbert, 1988, p. 3.
