The Catholic solution of our problem, of our unique vital problem, the problem of the immortality and eternal salvation of the soul, satisfies the will, and therefore satisfies life; but the attempt to rationalize it by means of a dogmatic theology fails to satisfy the reason. And reason has its exigencies as imperious as those of life. It is no use seeking to force ourselves to consider as super-rational what clearly appears to us to be contra-rational... Infallibility, a notion of Hellenic origin, is in its essence a rationalistic category.
