Proposition — Part III
Latin
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.
