Habits support the intelligence just as a way of living leads to a way of life.
(In Io. Ev. XVIII, 7)
There is an origin and source of virtue. There is a root of wisdom. And, there is, so to speak, a region of changeless truth. If the soul leaves this region, it lives in darkness but, when it approaches this region, it is enlightened.
(En. in ps. 58, S 1, 18)
God wished to sow in every soul the seeds of intelligence and wisdom.
