Grace, coming down upon someone, does not bring much factual knowledge, but teaches a human person the duty to pay careful attention to the contemplation of things. It does not create a context for interpreting the laws of knowledge, but pours onto a person love of truth which does not allow that one to deviate from the right ways to truth and to rely too much on abstractions. Thus it provides a middle ground of truth which cannot be reached without Grace … A scientific man develops a specific method of research, a kind of intuition in disclosing truth and true ways to this disclosure. This, in turn, being supported by virtues of the mind returning to the heart … communicates to the works of this mind such properties as successfulness, solidity, and fruitfulness.
