obscurity of our investigations; bright moments sometimes illuminate our path like lightning. But what is to be expected of heads of which even the wisest is every night the scene of the strangest and most senseless dreams, and which has to take up its meditations again on awakening from these? Clearly a consciousness which is subject to such great limitations is little suited for solving the riddle of the world; and such an endeavour would necessarily appear strange and pitiful to a being of a higher order whose intellect had not time as its form, and whose thinking had thus true completeness and unity. Indeed it is really wonderful that we are not completely confused by the very heterogeneous mixture of ideas and fragments of thought of every kind which are constantly crossing each other in our minds, but are yet always able to see our way again and make everything agree together. Clearly there must exist a simpler thread upon which everything ranges itself together: but what is this? Memory alone is not sufficient, for it has essential limitations of which I shall speak shortly, and besides this, it is exceedingly imperfect and untrustworthy. The logical ego or even the transcendental synthetic unity of apperception are expressions and explanations which will not easily serve to make the matter comprehensible; they will rather suggest to many:
"'Tis true your beard is curly, yet it will not draw you the bolt."
Kant's proposition, "The I think must accompany all our ideas," is insufficient; for the "I" is an unknown quantity, i.e., it is itself a secret. That which gives unity and connection to consciousness in that it runs through all its ideas, and is thus its substratum, its permanent supporter, cannot itself be conditioned by consciousness, therefore cannot be an idea. Rather it must be the prius of consciousness, and the root of the tree of which that is the fruit. This, I say, is the will. It alone is unchangeable and absolutely identical, and has brought
