Famous quotes containing the words mental and/or conditions:
“The very hope of experimental philosophy, its expectation of constructing the sciences into a true philosophy of nature, is based on induction, or, if you please, the a priori presumption, that physical causation is universal; that the constitution of nature is written in its actual manifestations, and needs only to be deciphered by experimental and inductive research; that it is not a latent invisible writing, to be brought out by the magic of mental anticipation or metaphysical mediation.”
—Chauncey Wright (1830–1875)
“... we have every reason to rejoice when there are so many gains and when favorable conditions abound on every hand. The end is not yet in sight, but it can not be far away. The road before us is shorter than the road behind.”
—Lucy Stone (1818–1893)
