[CTrent1564]

slyfox:

It is more accurate to say re-discovered them, much of the great Greek Philosophical writings were lost to Western Christendom for a while given the Muslim advances in much of the old part of the Eastern Roman empire. As the West gradually won some territory back, it was able to re-discover these Greek writings and update translations and bring them back to the West.

[Slyfox]

Rediscovery is basically true, but for Bishop Raymond of Toledo Aristotle's Ethics and Politics had never been seen. It is difficult to gauge what it all would have been like had those two works been generally known to the West at the same time that the muslims had them.

It seems to me that God allowed for them to be hidden until they could go through the mind of Aquinas.

Aquinas's main job at the University of Paris was to set up the groups who would correct the misinterpretations by the first translators. And that is why his knowledge, especially of Aristotle's Ethics was so precise.
