E3P30

Proposition — Part III

Latin

Si quis aliquid egit quod reliquos lætitia afficere imaginatur, is lætitia concomitante idea sui tanquam causa afficietur sive se ipsum cum lætitia contemplabitur. Si contra aliquid egit quod reliquos tristitia afficere imaginatur, se ipsum cum tristitia contra contemplabitur.

English (Elwes 1883)

If anyone has done something which he conceives as affecting other men pleasurably, he will be affected by pleasure, accompanied by the idea of himself as cause; in other words, he will regard himself with pleasure. On the other hand, if he has done anything which he conceives as affecting others painfully, he will regard himself with pain.

Modern English

If someone does something he imagines affects others with joy, he will be affected with joy accompanied by the idea of himself as cause, that is, he will regard himself with joy. If on the other hand he does something he imagines affects others with sadness, he will regard himself with sadness.
