Note 27 — Chapter V · OF DEMONSTRATION, AND NECESSARY TRUTHS.

"If all mankind had spoken one language, we cannot doubt that there would have been a powerful, perhaps a universal, school of philosophers, who would have believed in the inherent connexion between names and things, who would have taken the sound man to be the mode of agitating the air which is essentially communicative of the ideas of reason, cookery, bipedality, &c."—De Morgan, Formal Logic, p. 246.
