Cf. Spinoza, Ethica, iii. 11, schol.; Hobbes, Leviathan, i. 6, p. 25; Bain, The Senses and the Intellect, p. 283. Professor Bain's statement is carefully guarded: "A very considerable number of the facts may be brought under the following principle—namely, that states of pleasure are connected with an increase, and states of pain with an abatement, of some, or all, of the vital functions."
