Proposition — Part III

Latin

Qui id quod amat lætitia vel tristitia affectum imaginatur, lætitia etiam vel tristitia afficietur et uterque hic affectus major aut minor erit in amante prout uterque major aut minor est in re amata.

English (Elwes 1883)

He who conceives, that the object of his love is affected pleasurably or painfully, will himself be affected pleasurably or painfully; and the one or the other emotion will be greater or less in the lover according as it is greater or less in the thing loved.

Modern English

Whoever imagines that the thing he loves is affected with joy or sadness will also be affected with joy or sadness, and each of these affects will be greater or less in the lover in proportion as it is greater or less in the thing loved.
