“Then, things which in taking place are free from any necessity as to their being in the present must also, before they take place, be about to happen without necessity. Wherefore there are things which will come to pass, the occurrence of which is perfectly free from necessity. At all events, I imagine that no one will deny that things now taking place were about to come to pass before they were actually happening. Such things, however much foreknown, are in their occurrence free . For even as knowledge of things present imports no necessity into things that are taking place, so foreknowledge of the future imports none into things that are about to come. But this, thou wilt say, is the very point in dispute—whether any foreknowing is possible of things whose occurrence is not necessary. For here there seems to thee a contradiction, and, if they are foreseen, their necessity follows; whereas if there is no necessity, they can by no means be foreknown; and thou thinkest that nothing can be grasped as known unless it is certain, but if things whose occurrence is uncertain are foreknown as certain, this is the very mist of opinion, not the truth of knowledge. For to think of things otherwise than as they are, thou believest to be incompatible with the soundness of knowledge.
