suave est, persequitur vir prudens). Therefore with him the future constantly borrows from the present, instead of the present borrowing from the future, as is the case with a frivolous fool, who thus becomes impoverished and finally bankrupt. In the case of the former reason must, for the most part, assume the rôle of a churlish mentor, and unceasingly call for renunciations, without being able to promise anything in return, except a fairly painless existence. This rests on the fact that reason, by means of its conceptions, surveys the whole of life, whose outcome, in the happiest conceivable case, can be no other than what we have said.
When this striving after a painless existence, so far as it might be attainable by the application of and strict adherence to rational reflection and acquired knowledge of the true nature of life, was carried out with the greatest consistency and to the utmost extreme, it produced cynicism, from which stoicism afterwards proceeded. I wish briefly here to bring this out more fully for the sake of establishing more firmly the concluding exposition of our first book.
All ancient moral systems, with the single exception of that of Plato, were guides to a happy life. Accordingly in them the end of virtue was entirely in this life, not beyond death.

For certainly this would be the touchstone of an ethical system of this kind; the practice of it must give happiness directly and unconditionally. If it cannot do this it does not accomplish what it ought,
