"If experience actually presents esthetic and moral traits, then these traits may also be supposed to reach down into nature, and to testify to something that belongs to nature as truly as does the mechanical structure attributed to it in physical science. To rule out that possibility by some general reasoning is to forget that the very meaning and purport of empirical method is that things are to be studied on their own account, so as to find out what is revealed when they are experienced. The traits possessed by the subject-matters of experience are as genuine as the characteristics of sun and electron. They are found, experienced, and are not to be shoved out of being by some trick of logic. When found, their ideal qualities are as relevant to the philosophic theory of nature as are the traits found by physical inquiry." -- John Dewey, Experience and Nature (LW 1: 13-14)
