Note 18 — Chapter V · OF THE IMPORT OF PROPOSITIONS.
Reading edition
"From hence also this may be deduced, that the first truths were arbitrarily made by those that first of all imposed names upon things, or received them from the imposition of others. For it is true (for example) that man is a living creature, but it is for this reason, that it pleased men to impose both these names on the same thing."—Computation or Logic, ch. iii. sect. 8.
