Consciousness never deceives.... We learn the influence of our will from experience alone. And experience only teaches us, how one event constantly follows another; without instructing us in the secret connexion, which binds them together, and renders them inseparable.
David Hume (1711–1776), Scottish philosopher. Enquiries Concerning the Human Understanding and Concerning the Principles of Morals, sect. 7 ("Of the Idea of Necessary Connexion"), part 1, p. 66, ed. L. Selby-Bigge, M.A., 2nd edition, London, Oxford University Press (1902).
