A man's real faith is never contained in his creed, nor is his creed an article of his faith. The last is never adopted. This it is that permits him to smile ever, and to live even as bravely as he does. And yet he clings anxiously to his creed, as to a straw, thinking that that does him good service because his sheet anchor does not drag.
Henry David ThoreauThis was sheer idleness to my fellow-townsmen, no doubt; but if the birds and flowers had tried me by their standard, I should not have been found wanting. A man must find his occasions in himself, it is true. The natural day is very calm, and will hardly reprove his indolence.
Henry David ThoreauThe study of geometry is a petty and idle exercise of the mind, if it is applied to no larger system than the starry one. Mathematics should be mixed not only with physics but with ethics; that is mixed mathematics.
Henry David Thoreau
