In this treatise Proclus discusses ten problems on providence and fate, foreknowledge of the future, human responsibility, evil and punishment (or seemingly absence of punishment), social and individual responsibility for evil, and the unequal fate of different animals. These problems, he admits, had been discussed a thousand times in and outside philosophical schools. Yet, as he put it: we too have to discuss them, not because we imagine that the philosophers before us have said anything valuable, but because our soul desires 'to speak and hear about these problems and wants to turn to itself and to discuss as it were with itself and is not willing to take arguments about these issues only from authorities outside'. Proclus exhorts his readers: we are to use his treatise as an opportunity to investigate these problems for ourselves 'in the secret recess of our soul' and 'exercise ourselves in the solutions of problems'. In fact, it makes no difference whether what we discuss has been said before by philosophers, so long as we express what corresponds to our own views. This exhortation may be the best presentation of the translation of this wonderful treatise from late antiquity.
