Wretchedness induces despair. Pride produces presumption. The incarnation shows man the greatness of his wretchedness through the greatness of the re… - Blaise Pascal

One, knowing the duties of man and being ignorant of his impotence, is lost in presumption, and that the other, knowing the impotence and being ignorant of the duty, falls into laxity; whence it seems that since the one leads to truth, the other to error, there would be formed from their alliance a perfect system of morals. But instead of this peace, nothing but war and a general ruin would result from their union; for the one establishing certainty, the other doubt, the one the greatness of man, the other his weakness, they would destroy the truths as well as the falsehoods of each other. So that they cannot subsist alone because of their defects, nor unite because of their opposition, and thus they break and destroy each other to give place to the truth of the Gospel. This it is that harmonizes the contrarieties by a wholly divine act, and uniting all that is true and expelling all that is false, thus makes of them a truly celestial wisdom in which those opposites accord that were incompatible in human doctrines.

The heart has its reasons which reason knoweth not.

God wishes to move the will rather than the mind. Perfect clarity would help the mind and harm the will. Humble their pride.
