Famous quotes containing the words direct and/or causation:
“An inexperienced heraldist resembles a medieval traveler who brings back from the East the faunal fantasies influenced by the domestic bestiary he possessed all along rather than by the results of direct zoological exploration.”
—Vladimir Nabokov (1899–1977)
“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)
