God, I have said, is the fulfiller, or the reality, of the human desires for happiness, perfection, and immortality. From this it may be inferred that to deprive man of God is to tear the heart out of his breast. But I contest the premises from which religion and theology deduce the necessity and existence of God, or of immortality, which is the same thing. I maintain that desires which are fulfilled only in the imagination, or from which the existence of an imaginary being is deduced, are imaginary desires, and not the real desires of the human heart; I maintain that the limitations which the religious imagination annuls in the idea of God or immortality, are necessary determinations of the human essence, which cannot be dissociated from it, and therefore no limitations at all, except precisely in man’s imagination.

Religion is the dream of the human mind. But even in dreams we do not find ourselves in emptiness or in heaven, but on earth, in the realm of reality; we only see real things in the entrancing splendor of imagination and caprice, instead of in the simple daylight of reality and necessity.

Hegel determines and presents only the most striking differences of various religions, philosophies, time and peoples, and in a progressive series of stages, but he ignores all that is common and identical in all of them. … His system knows only subordination and succession; coordination and coexistence are unknown to it.

A subject interests me and holds my attention only so long as it presents me with difficulties, only so long as I am at odds with it and have, as it were, to struggle with it; but once I have mastered it I hurry on to something else, to a new subject; for my interest is not confined to any particular field or subject; it extends to everything human. This does not mean that I am an intellectual miser or egoist, who amasses knowledge for himself alone; by no means! What I do and think for myself, I must also think and do for others. But I feel the need of instructing others in a subject only so long as, while instructing others, I am also instructing myself.

The secret of Hegel's dialectic lies ultimately in this alone, that it negates theology through philosophy in order then to negate philosophy through theology. Both the beginning and the end are constituted by theology; philosophy stands in the middle as the negation of the first positedness, but the negation of the negation is again theology. At first everything is overthrown, but then everything is reinstated in its old place, as in Descartes. The Hegelian philosophy is the last grand attempt to restore a lost and defunct Christianity through philosophy, and, of course, as is characteristic of the modern era, by identifying the negation of Christianity with Christianity itself.

What man calls Absolute Being, his God, is his own being. The power of the object over him is therefore the power of his own being. Thus, the power of the object of feeling is the power of feeling itself; the power of the object of reason is the power of reason itself; and the power of the object of will is the power of will itself.
