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.

Though I myself am an atheist, I openly profess religion in the sense just mentioned, that is, a nature religion. I hate the idealism that wrenches man out of nature; I am not ashamed of my dependency on nature; I openly confess that the workings of nature affect not only my surface, my skin, my body, but also my core, my innermost being, that the air I breathe in bright weather has a salutary effect not only on my lungs but also on my mind, that the light of the sun illumines not only my eyes but also my spirit and my heart. And I do not, like a Christian, believe that such dependency is contrary to my true being or hope to be delivered from it. I know further that I am a finite moral being, that I shall one day cease to be. But I find this very natural and am therefore perfectly reconciled to the thought.

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

Faith in a written revelation is a real, unfeigned, and so far respectable faith, only where it is believed that all in the sacred writings is significant, true, holy, divine. Where, on the contrary, the distinction is made between the human and divine, the relatively true and the absolutely true, the historical and the permanent, - where it is not held that all without distinction is unconditionally true; there the verdict of unbelief, that the Bible is no divine book, is already introduced into the interpretation of the Bible, - … it's title to the character of a divine revelation is denied. Unity, unconditionality, freedom from exceptions, immediate certitude, is alone the character of divinity. A book that imposes on me the necessity of discrimination, the necessity of criticism, in order to separate the divine from the human, the permanent from the temporary, is no longer a divine, certain, infallible book, - it is degraded[.]
