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)
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.
