BOOK V.
whether virtue alone be sufficient for a happy life.
I. This fifth day, Brutus, shall put an end to our Tusculan Disputations: on which day we discussed your favorite subject. For I perceive from that book which you wrote for me with the greatest accuracy, as well as from your frequent conversation, that you are clearly of this opinion, that virtue is of itself sufficient for a happy life: and though it may be difficult to prove this, on account of the many various strokes of fortune, yet it is a truth of such a nature that we should endeavor to facilitate the proof of it.
