For Hippocrates, Epidem V. 14. the great physician, in my opinion took the most honourable course in acknowledging some of his errors to prevent those who came after from being led astray, while Cicero had no hesitation about condemning some of his earlier works in books which he published later: I refer to his condemnation of his Lucullus and Catulus The two books of the first edition of the Academica. and the books i.e. the Rhetorica, better known as de Inventione. on rhetoric which I have already mentioned.

Still none of my past teaching was superfluous: for the views which I am now going to produce will be found to be based on the same principles, and consequently no one need be sorry to have attended my lectures, since all that I am now attempting to do is to collect and rearrange my original views so that they may be somewhat more instructive. But I wish to satisfy everybody and not to lay myself open to the accusation that I have allowed a long time to elapse between the formation and publication of my views.
