We never know, believe me, when we have succeeded best. - Miguel de Unamuno

Proceeding from ourselves, from our own human consciousness, the only consciousness which we feel from within and in which feeling is identical with being, we attribute some sort of consciousness, more or less dim, to all living things, and even to the stones themselves, for they also live. And the evolution of organic beings is simply the struggle to realize fullness of consciousness through suffering, a continual aspiration to be others without ceasing to be themselves, to break and yet to preserve their proper limits.

We must needs believe with faith, whatever counsels reason may give us, that in the depths of our own bodies, in animals, in plants, in rocks, in everything that lives, in all the Universe, there is a spirit that strives to know itself, to acquire consciousness of itself, to be itself — for to be oneself is to know oneself — to be pure spirit; and since it can only achieve this by means of the body, by means of matter, it creates and makes use of matter at the same time that it remains a prisoner of it.

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.
