Faith is peace of heart arising from an almost boundless certainty, thus by its very nature falling outside the jurisdiction of doubt; human intelligence is made for transcendence, for otherwise it would be nothing more than an increase in animal intelligence. Apart from the content that completes it, faith is our disposition to know before knowing; indeed this disposition is already knowledge in that it is derived from innate wisdom, which it is precisely the function of the revealed content of faith to revive.

A man may have metaphysical certainty without having "faith", that is, without this certainty residing in his soul as a continuously active presence. But if metaphysical certainty suffices on doctrinal grounds, it is far from being sufficient on the spiritual plane, where it must be completed and brought to life by faith. Faith is nothing other than the adherence of our whole being to Truth, whether we have a direct intuition of this Truth or an indirect notion.

In the elementary sense of the word, faith is our assent to a truth that transcends us; but spiritually speaking, it is our assent, not to transcendent concepts, but to immanent realities, or to Reality as such; now this Reality is our very substance.

The fact that spiritual realism, or faith, pertains to the intelligence of the heart and not to that of the mind, enables one to understand that in spirituality, the moral qualification takes precedence over the intellectual qualification, and by far.

One cannot state too clearly that a doctrinal formulation is perfect, not because it exhausts the infinite Truth on the plane of logic, which is impossible, but because it realizes a mental form capable of communicating, to whoever is intellectually apt to receive it, a ray of that Truth, and thereby a virtuality of the total Truth. This explains why the traditional doctrines are always apparently naive, at least from the point of view of philosophers − that is to say, of men who do not understand that the goal and sufficient reason of wisdom do not lie on the plane of its formal affirmation; and that, by definition, there is no common measure and no continuity between thought, whose operations have no more than a symbolic value, and pure Truth, which is identical with That which "is" and thereby includes him who thinks.

The first of the virtues is veracity, for without truth we can do nothing. The second virtue is sincerity, which consists in drawing the consequences of what we know to be true, and which implies all the other virtues; for it is not enough to acknowledge the truth objectively, in thought, it must also be assumed subjectively, in acts, whether outward or inward. Truth excludes heedlessness and hypocrisy as much as error and lying.

What the virtues are to existential perfection, truths are to intellectual perfection; virtue is essentially simplicity, inward beauty, generosity, whereas truth, for its part, lies entirely in the discernment between the Real and the illusory or between the Absolute and the contingent.

We are surrounded by a world of tumult and incertitude; and there are sudden encounters with things that are surprising, incomprehensible, absurd or disappointing. But these things have no right to be problems for us, if only because every phenomenon has its causes, whether we know them or not. Whatever may be the phenomena and whatever their causes, there is always That Which Is; and That Which Is, lies beyond the world of tumult, contradictions, and disappointments. That Which Is can be troubled and diminished by nothing; It is Truth, Peace, and Beauty. Nothing can tarnish It, and no one can take It from us.

We must distinguish between natural life, which is centrifugal, and supernatural life, which is centripetal; the first pulls the soul away from God and drives it into the world, whereas the second draws the soul away from the world and leads it back to God. Natural or centrifugal life comprises one effect which is dispersion and another which is compression: the profane or worldly man loses himself in the multitude of things, on the one hand, and becomes hardened in his passional attachments, on the other hand. The supernatural life, on the contrary, comprises one effect which is dilation and another which is concentration: the spiritual man is dilated towards the Interior, on the one hand, and is united to the Unique on the other hand, the one being the function of the other.
