And as on this subject there is great difference of opinion among the most learned men, who can think it inconsistent with that dignity which every one allows to belong to me, to examine what is in every situation in life the best and truest good? Shall the chief men of the city, Publius Scævola and Marcus Manilius argue whether the offspring of a female slave ought to be considered the gain of the master of the slave; and shall Marcus Brutus express his dissent from their opinion, (and this is a kind of discussion giving great room for the display of acuteness, and one too that is of importance as regards the citizens,) and do we read, and shall we continue to read, with pleasure their writings on this subject, and the others of the same sort, and at the same time neglect these subjects, which embrace the whole of human life? There may, perhaps, be more money affected by discussions on that legal point, but beyond all question, this of ours is the more important subject: that, however, is a point which the readers may be left to decide upon. But we now think that this whole question about the ends of good and evil is, I may almost say, thoroughly explained in this treatise, in which we have endeavoured to set forth as far as we could, not only what our own opinion was, but also everything which has been advanced by each separate school of philosophy.

For we are desirous of ascertaining the truth; not of convicting some adversary.
