EPICTETUS. DISCOURSES. Book ii. §1. ¶1.
WHAT is asserted by the philosophers may, perhaps, appear a paradox to some: let us, however, examine, as well as we can, whether this be true: That it is possible in all things to act at once with caution and courage. For caution seems, in some measure, contrary to courage; and contraries are by no means consistent. The appearance of a paradox to many, in the present case, seems to me to arise from something like this. If, indeed, we assert that courage and caution are to be used in the same instances, we should justly be accused of uniting contradictions: but, in the way that we afifirm it, where is the absurdity? For, if what hath been so often said, and so often demonstrated, be certain, that the essence of good and evil consists in the use of the appearances; and that things independent on choice are not of the nature either of good or evil: what paradox do the philosophers assert, if they say: "Where things are not dependent on choice, be courageous; where they are, be cautious?" For in these only, if evil consists in a bad choice, is caution to be used.
