The history of philosophical system is the picture gallery of reason. - Ludwig Feuerbach

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.

Hegel … proceeds abstractly from the pre-existence of the intellect. … He does not appeal to the intellect within us.

To prove cannot mean anything other than to bring the other person to my own conviction. The truth lies only in the unification of “I” and “You.” The Other of pure thought, however, is the sensuous intellect in general. In the field of philosophy, proof therefore consists only in the fact that the contradiction between sensuous intellect and pure thought is disposed, so that thought is true not only for itself but also for its opposite.
