"The real sin — perhaps it is a sin against the Holy Ghost for which there is no remission — is the sin of heresy, the sin of thinking for oneself. The saying has been heard before now, here in Spain, that to be a liberal — that is, a heretic — is worse than being an assassin, a thief, or an adulterer. The gravest sin is not to obey the Church, whose infallibility protects us from reason."

“Faith feels itself secure neither with universal consent, nor with tradition, nor with authority. It seeks support of its enemy, reason.”

“There are, in fact, people who appear to think only with the brain, or with whatever may be the specific thinking organ; while others think with all the body and all the soul, with the blood, with the marrow of the bones, with the heart, with the lungs, with the belly, with the life. And the people who think only with the brain develop into definition-mongers; they become the professionals of thought.”

“Just as eunuchs will never know aesthetics as applied to the selection of beautiful women, so neither will pure rationalists ever know ethics, nor will they ever succeed in defining happiness, for happiness is a thing that is lived and felt, not a thing that is reasoned or defined.”

“And the upshot of all this," so I have been told more than once and by more than one person, "will be simply that all you will succeed in doing will be to drive people to the wildest Catholicism." And I have been accused of being a reactionary and even a Jesuit. Be it so! ...I know very well it is madness to seek to turn the waters of the river back to their source, and that it is only the ignorant who seek to find in the past a remedy for their present ills; but I know too that anyone who fights for any ideal whatever, although his ideal may seem to lie in the past, is driving the world on to the future, and that the only reactionaries are those who find themselves at home in the present. Every supposed restoration of the past is a creation of the future, and if the past which it is sought to restore is a dream, something imperfectly known, so much the better.”

“In books of psychology written from the spiritualist point of view, it is customary to begin the discussion of the existence of the soul as a simple substance, separable from the body, after this style: There is in me a principle which thinks, wills and feels... Now this implies a begging of the question. For it is far from being an immediate truth that there is in me such a principle; the immediate truth is that I think, will and feel. And I — the I that thinks, wills and feels — am immediately my living body with the states of consciousness which it sustains. It is my living body that thinks, wills and feels.”

“And thus the soul pities God and feels itself pitied by him; loves Him and feels loved by Him, sheltering its misery in the bosom of the eternal and infinite misery, which, in eternalizing itself and infinitizing itself, is the supreme happiness itself.”
