Here’s some food for thought, courtesy of the latest issue of Communio (XXXV, Fall 2008).
All that is exists because it was thought by God. Therefore all creation can be seen as ontologically bearing that mark of divine reason; all creation meaning what is material and what is immaterial (e.g. reason, intellect, nous, etc.). In the context of natural law and the phenomenon of conscience, man participates in the divine reason by way of the memory (anamnesis) implanted in him at his beginning. In this way when man thinks (as a created being), he re-thinks the divine reason of which he is a part.
It follows from this traditional view that that human thinking is the re-thinking of being itself. Man can re-think the logos, the meaning of being, because his own logos, his own reason, is logos in the one logos, thought of the original thought, of the creative spirit that permeates and governs his being.
