To theology, ... only what it holds sacred is true, whereas to philosophy, only what holds true is sacred.

I would rather be a devil in alliance with truth, than an angel in alliance with falsehood.

If therefore my work is negative, irreligious, atheistic, let it be remembered that atheism — at least in the sense of this work — is the secret of religion itself; that religion itself, not indeed on the surface, but fundamentally, not in intention or according to its own supposition, but in its heart, in its essence, believes in nothing else than the truth and divinity of human nature.

Christianity set itself the goal of fulfilling man’s unattainable desires, but for that very reason ignored his attainable desires. By promising man eternal life, it deprived him of temporal life, by teaching him to trust in God’s help it took away his trust in his own powers; by giving him faith in a better life in heaven, it destroyed his faith in a better life on earth and his striving to attain such a life. Christianity gave man what his imagination desires, but for that very reason failed to give him what he really and truly desires.

Faith does not limit itself by the idea of a world, a universe, a necessity.

Faith in the power of prayer … is … faith in miraculous power; and faith in miracles is … the essence of faith in general. … [F]aith is nothing else than confidence in the reality of the subjective in opposition to the limitations or laws of Nature and reason, … The specific object of faith, therefore, is miracle; … To faith nothing is impossible, and miracle only gives actuality to this omnipotence of faith[.]

The power of thought is the light of knowledge, the power of will is the energy of character, the power of heart is love. Reason, love and power of will are perfections of man.

The task of the modern era was the realization and humanization of God – the transformation and dissolution of theology into anthropology.

As we expand our knowledge of good books, we shrink the circle of men whose company we appreciate.

[T]he present age, which prefers the sign to the thing signified, the copy to the original[.]

In reality, where everything passes on naturally, the copy follows the original, the image the thing which it represents, the thought its object, but on the supernatural, miraculous ground of theology, the original follows the copy, the thing its own likeness."it is strange" says St. Augustine, "But nevertheless true, that this world could not exist if it was not known to God." That means the world is known and thought before it exists; nay it exists only because it was thought of. The existence is a consequence of the knowledge or of the act of thinking, the original a consequence of the copy, the object a consequence of its likeness.

[L]et it be remembered that atheism … is the secret of religion … ; religion … in its heart, in its essence, believes in nothing else than the truth and divinity of human nature.

I do not regard the limits of the past and present as the limits of humanity of the future

[This philosophy] … is antagonistic to minds perverted and crippled by a superhuman

How can the feeling man resist feeling, the loving one love? Who has not experienced the overwhelming power of melody? And what else is melody but the power of feeling? Music is the language of feeling; … feeling communicates itself. … Is it man that possesses love, or is it not … love that possesses man? When love impels a man to suffer death even joyfully for the beloved one, is this death-conquering power his own individual power, or is it not rather the power of love?

The notion that the fulfilment of prayer has been determined from eternity, that it was originally included in the plan of creation, is the empty, absurd fiction of a mechanical mode of thought, which is in absolute contradiction with the nature of religion. Whether God decides on the fulfilment of my prayer now, on the immediate occasion of my offering it, or whether he did decide on it long ago, is the same thing.

Faith in Providence is faith in one's own worth, … [H]ence also false humility, religious arrogance, which, it is true, does not rely on itself, but only because it commits the care of itself to the blessed God. God … wills that I shall be blest; but that is my will also: … God's love for me [is] nothing else than my own self-love deified.

[T]he understanding or the reason is the necessary being. … [I]f there were no reason, no consciousness, all would be nothing; existence would be equivalent to non-existence. Consciousness first founds the distinction between existence and non-existence. In consciousness is first revealed the value of existence, the value of nature.

Consciousness consists in a being becoming objective to itself; … it is nothing apart, nothing distinct from the being which is conscious of itself.

Wherever morality is based on theology, wherever right is made dependent on divine authority, the most immoral, unjust, infamous things can be justified and established.

The Jewish people trusted themself to do nothing except that what was commanded by God; they were without will even in external things; the authority of religion extended itself even to their food. The Christian religion, on the other hand, in all external things made humankind dependent on itself, i.e. placed in it what Judaism placed out of itself. … Thus do things change. What yesterday was still religion is no longer such to-day; and what to-day is atheism, to-morrow will be religion.

Certainly my work is negative, destructive; but … only in relation to the unhuman, not to the human[.]

[This philosophy] does not … regard the pen as the only fit organ for the revelation of truth, but the eye and ear, the hand and foot

[T]here is no distinction between the predicates of the divine and human nature, and, consequently, no distinction between the divine and human subject … [T]he predicates are not accidents, but express the essence of the subject … [T]he essence of religion … conceives and affirms a profoundly human relation as divine relations[.]

I by no means say … God is nothing, the Trinity is nothing, the Word of God is nothing, … . I only show that they are not that which the illusions of theology make them[.]

[T]hese days illusion only is scared, truth profane. … [S]acredness is held to be enhanced in proportion as truth decreases and illusion increases, so that the highest degree of illusion comes to highest degree of sacredness. Religion has disappeared, … for it has been substituted … the appearance of religion[.]

[D]oubt, the principle of theoretic freedom, appears to me a crime. … [T]he highest crime is doubt in God, or the doubt that God exists. … [T]hat which I do not trust myself to doubt, … without feeling disturbed in my soul, without incurring guilt; that is no matter of theory, but a matter of conscience[.]

[I]f God as a subject is the determined, while the quality, the predicate, is determining, then in truth the rank of the godhead is due not to the subject, but to the predicate.

But certainly for the present age, which prefers the sign to the thing signified, the copy to the original, representation to reality, the appearance to the essence... illusion only is sacred, truth profane. Nay, sacredness is held to be enhanced in proportion as truth decreases and illusion increases, so that the highest degree of illusion comes to be the highest degree of sacredness.

The essence of faith … is the idea that that which man wishes actually is: he wishes to be immortal, therefore he is immortal; he wishes for the existence of a being who can do everything which is impossible to Nature and reason, therefore such a being exists[.]

[I]n love, man declares himself unsatisfied in his individuality taken by itself, he postulates the existence of another as a need of the heart; … the life which he has through love to be the truly human life, … The individual is defective, imperfect, weak, needy; but love is strong, perfect, contented, free from wants, self-sufficing, infinite; … friendship is a means of virtue, and more: it is … dependent however on participation. … [I]t cannot be based on perfect similarity; on the contrary, it requires diversity, for friendship rests on a desire for self-contemplation. One friend obtains through the other what he does not himself possess. … However faulty a man may be, it is a proof that there is a germ of good in him if he has worthy men for his friends. If I cannot be myself perfect, I yet at least love virtue, perfection in others.
