A life of pleasure is either a real evil, and in that case we ought not to assist others in their pursuit of it, but, on the contrary, to keep them from it all we can, as from that which is most hurtful and deadly; or if it is a good thing, so that we not only may but ought to help others to it, why, then, ought not a man to begin with himself? since no man can be more bound to look after the good of another than after his own; for Nature cannot direct us to be good and kind to others, and yet at the same time to be unmerciful and cruel to ourselves.
