E3P27

Proposition — Part III

Latin

Ex eo quod rem nobis similem et quam nullo affectu prosecuti sumus, aliquo affectu affici imaginamur, eo ipso simili affectu afficimur.

English (Elwes 1883)

By the very fact that we conceive a thing, which is like ourselves, and which we have not regarded with any emotion, to be affected with any emotion, we are ourselves affected with a like emotion (affectus).

Modern English

By the very fact that we conceive a thing similar to ourselves, one toward which we have had no affect, to be affected with any affect, we are ourselves affected with a like affect.
