Religion ultimately then rests upon the practical reason, and expresses some demand or want of the pure ego.
Fichte transformed this unity of the conscious self into a unity of all conscious selves, or a common consciousness; and this change enabled him to explain the unity of anything produced by the Ego by contending that it is not the different objects of different thinkers, but the one object of a pure Ego or consciousness common to them all.
The pure ego is inferred from the fact that the non-ego is realized only in the act of the ego in positing it.
And, therefore, finding on reflection any particular concrete factor contingent, we abstract the position from that which occupies it, and so reach the speculative notion of the pure Ego.
