"Consciousness (conscientia) is participated knowledge, is co-feeling, and co-feeling is com-passion. Love personalizes all that it loves. Only by personalizing it can we fall in love with an idea. And when love is so great and so vital, so strong and so overflowing, that it loves everything, then it personalizes everything and discovers that the total All, that the Universe, is also a person possessing a Consciousness, a Consciousness which in its turn suffers, pities, and loves, and therefore is consciousness. And this Consciousness of the Universe, which a love, personalizing all that it loves, discovers, is what we call God."

"And if it is grievous to be doomed one day to cease to be, perhaps it would be more grievous still to go on being always oneself, and no more than oneself, without being able to be at the same time other, without being able to be at the same time everything else, without being able to be all."

"I have told you that... we know nothing save what we have first, in one way or another, desired; and it may even be added that we can know nothing well save what we love, save what we pity."

"I will not say that the more or less poetical and unphilosophical doctrines that I am about to set forth are those which make me live; but I will venture to say that it is my longing to live and to live for ever that inspires these doctrines within me. And if by means of them I succeed in strengthening and sustaining this same longing in another, perhaps when it is all but dead, then I shall have performed a man's work, and above all, I shall have lived. In a word, be it with reason or without reason or against reason, I am resolved not to die. And if, when at last I die out, I die altogether, then I shall not have died out of myself — that is, I shall not have yielded myself to death, but my human destiny shall have killed me. Unless I come to lose my head, or rather my heart, I will not abdicate from life — life will be wrested from me."

"For the truth is that our doctrines are usually only the justification a posteriori of our conduct, or else they are our way of trying to explain that conduct to ourselves."

"Yes, I know well that others before me have felt what I feel and express; that many others feel it today, although they keep silence about it. ...And I do not keep silence about it because it is for many the thing which must not be spoken, the abomination of abominations — infandum — and I believe that it is necessary now and again to speak the thing which must not be spoken. ...Even if it should lead only to irritating the devotees of progress, those who believe that truth is consolation, it would lead to not a little. To irritating them and making them say: "Poor fellow! if he would only use his intelligence to better purpose!... Someone perhaps will add that I do not know what I say, to which I shall reply that perhaps he may be right — and being right is such a little thing! — but that I feel what I say and I know what I feel and that suffices me. And that it is better to be lacking in reason than to have too much of it."

"I know that all this is dull reading, tiresome, perhaps tedious, but it is all necessary. And I must repeat once again that we have nothing to do with a transcendental police system or with the conversion of God into a great Judge or Policeman — that is to say, we are not concerned with heaven or hell considered as buttresses to shore up our poor earthly mortality, nor are we concerned with anything egoistic or personal. It is not I myself alone, it is the whole human race that is involved, it is the ultimate finality of all our civilization. I am but one, but all men are I's."

"I do not understand these men who tell me that the prospect of the yonder side of death has never tormented them, that the thought of their own annihilation never disquiets them. For my part I do not wish to make peace between my heart and my head, between my faith and my reason — I wish rather that there should be war between them."

"There may be a rationalist who has never wavered in his conviction of the mortality of the soul, and there may be a vitalist who has never wavered in his faith in immortality; but at the most this would prove that just as there are natural monstrosities, so there are those who are stupid as regards heart and feeling, however great their intelligence, and those who are stupid intellectually, however great their virtue. But, in normal cases, I cannot believe those who assure me that never, not in a fleeting moment, not in the hours of direst loneliness and grief, has this murmur of uncertainty breathed upon their consciousness."

"In the most secret chamber of the spirit of him who believes himself convinced that death puts an end to his personal consciousness, his memory, for ever, and all unknown to him perhaps, there lurks a shadow, a vague shadow, a shadow of uncertainty, and while he says within himself, "Well, let us live this life that passes away, for there is no other!" the silence of this secret chamber speaks to him and murmurs, "Who knows!... " These voices are like the humming of a mosquito when the south-west wind roars through the trees in the wood; we cannot distinguish this faint humming, yet nevertheless, merged in the clamor of the storm, it reaches the ear."

"To all this, someone is sure to object that life ought to subject itself to reason, to which we will reply that nobody ought to do what he is unable to do, and life cannot subject itself to reason. "Ought, therefore can," some Kantian will retort. To which we shall demur: "Cannot, therefore ought not." And life cannot submit itself to reason, because the end of life is living and not understanding."

"Philosophy and religion are enemies, and because they are enemies they have need of one another. There is no religion without some philosophical basis, no philosophy without roots in religion. … the attacks which are directed against religion from a presumed scientific or philosophical point of view are merely attacks from another but opposing religious point of view."

"To know something is to make this something that I know myself; but to avail myself of it, to dominate it, it has to remain distinct from myself."

"To believe in God is to yearn for His existence and, furthermore, it is to act as if He did exist."

"Feeling does not succeed in converting consolation into truth, nor does reason succeed in converting truth into consolation."

"La verdadera ciencia enseña, por encima de todo, a dudar y a ser ignorante. (True science teaches, above all, to doubt and be ignorant.)"

"Absolute relativism, which is neither more nor less than skepticism, in the most modern sense of the term, is the supreme triumph of the reasoning reason."

"El uso estropea y hasta destruye toda belleza. La función más noble de los objetos es la de ser contemplados."

"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."

"Science is a cemetery of dead ideas, even though life may issue from them."

"A terrible thing is intelligence. It tends to death as memory tends to stability. The living, the absolutely unstable, the absolutely individual, is strictly unintelligible. Logic tends to reduce everything to identities and genera, to each representation having no more than one self-same content in whatever place, time or relation it may occur to us. And there is nothing that remains for two successive moments of its existence. My idea of God is different each time that I conceive it. Identity, which is death, is the goal of the intellect. The mind seeks what is dead, for what is living escapes it; it seeks to congeal the flowing stream in blocks of ice; it seeks to arrest it. In order to analyze a body it is necessary to extenuate or destroy it. In order to understand anything it is necessary to kill it, to lay it out rigid in the mind."

"Neither is the longing for immortality saved, but rather dissolved and submerged, by agnosticism, or the doctrine of the unknowable. ...The unknowable, if it is something more than the merely hitherto unknown, is but a purely negative concept, a concept of limitation. And upon this foundation no human feeling can be built up."
