The discovery that the rising sun is not new every morning, but always the same, was one of the most fertile astronomical discoveries. Even to-day the identification of a small planet or a comet is not always a matter of course. Now if we were to regard equality as a relation between that which the names 'a' and 'b' designate, it would seem that a = b could not differ from a = a (i.e. provided a = b is true). A relation would thereby be expressed of a thing to itself, and indeed one in which each thing stands to itself but to no other thing.

“It is plain, of course, that any proof of this depends upon the validity of the doctrine of a priori cognition; only by our proved possession of such cognition can there be any evidence that we are self-active realities. It is in this reference noteworthy, therefore, that Lange, as defender of agnosticism, sees he cannot afford to admit the theory upon which alone cognition strictly a priori can be established.”

Context: There is a spiritual obligation, there is a task to be done. It is not, however, something as simple as following a set of somebody else's rules. The noetic enterprise is a primary obligation toward being. Our salvation is linked to it. Not everyone has to read alchemical texts or study superconducting biomolecules to make the transition. Most people make it naively by thinking clearly about the present at hand, but we intellectuals are trapped in a world of too much information. Innocence is gone for us. We cannot expect to cross the rainbow bridge through a good act of contrition; that will not be sufficient.
We have to understand. Whitehead said, "Understanding is the apperception of pattern as such"; to fear death is to misunderstand life. Cognitive activity is the defining act of humanness. Language, thought, analysis, art, dance, poetry, mythmaking: these are the things that point the way toward the realm of the eschaton. We humans may be released into a realm of pure self-engineering. The imagination is everything. This was Blake's perception. This is where we came from. This is where we are going. And it is only to be approached through cognitive activity.
