"Reference to experience, as here used, means reference to the known. The known is that which the listener has seen, heard, read, felt, believed or done, and which still exists in his consciousness—his stock of knowledge. It embraces all those thoughts, feelings and happenings which are to him real. Reference to Experience, then, means coming into the listener's life.[18]
The vast results obtained by science are won by no mystical faculties, by no mental processes, other than those which are practised by every one of us in the humblest and meanest affairs of life. A detective policeman discovers a burglar from the marks made by his shoe, by a mental process identical with that by which Cuvier restored the extinct animals of Montmartre from fragments of their bones. Nor does that process of induction and deduction by which a lady, finding a stain of a particular kind upon her dress, concludes that somebody has upset the inkstand thereon, differ in any way from that by which Adams and Leverrier discovered a new planet. The man of science, in fact, simply uses with scrupulous exactness the methods which we all habitually, and at every moment, use carelessly.
—Thomas Henry Huxley, Lay Sermons.
Do you set down your name in the scroll of youth, that are written down old with all the characters of age? Have you not a moist eye? a dry hand? a yellow cheek? a white beard? a decreasing leg? an increasing belly? is not your voice broken? your wind short? your chin double? your wit single? and every part about you blasted with antiquity? and will you yet call yourself young? Fie, fie, fie, Sir John!
—Shakespeare, The Merry Wives of Windsor.
