Famous quotes containing the words natural and/or proofs:
“After school days are over, the girls ... find no natural connection between their school life and the new one on which they enter, and are apt to be aimless, if not listless, needing external stimulus, and finding it only prepared for them, it may be, in some form of social excitement. ...girls after leaving school need intellectual interests, well regulated and not encroaching on home duties.”
—Ellen Henrietta Swallow Richards (1842–1911)
“To invent without scruple a new principle to every new phenomenon, instead of adapting it to the old; to overload our hypothesis with a variety of this kind, are certain proofs that none of these principles is the just one, and that we only desire, by a number of falsehoods, to cover our ignorance of the truth.”
—David Hume (1711–1776)
