Don't live by generalities, unless it be to act virtuously, and don't ask desire to follow precise laws, for you will have to drink tomorrow from the water you scorn today.
No vaya por generalidades en el vivir, si ya no fuere en favor de la virtud, ni intime leyes precisas al querer, que avrá de bever mañana del agua que desprecia hoi.
