The Third Problem of Evil

The problem is supposedly that there is no possible way that such a God and evil could coexist. The standard reason offered is that if God wanted to give us free will, he might allow evil to exist as a consequence of this freedom. I tend to think that philosophers of religion have succeeded in answering this version of the problem of evil. On other hand, Platonus believed that all things derive from a first principle which is perfectly good. This would be like if the form of horse caused some things not to be horses, or if water made things dry.
