St Peter of Damaskos

It is remarkable how the human intellect sees things differently according to its own light, even when these things are unalterable and in themselves remain what they are. It is because of this that we do not all have the same attitude to things, but each of us uses them as he wishes, whether for good or for-ill. We use sensible things in our practical activity, and intelligible things in thought and disputation.
