VIII. Are There Limits to Knowledge

In knowledge we are concerned with questions which arise for us through the fact that a world of percepts, conditioned by time, space, and our subjective organization, stands over against a world of concepts expressing the totality of the universe. Our task consists in the assimilation to one another of these two spheres, with both of which we are familiar. There is no room here for talking about limits of knowledge. It may be that, at a particular moment, this or that remains unexplained because, through chance obstacles, we are prevented from perceiving the things involved. What is not found today, however, may easily be found tomorrow. The limits due to these causes are only contingent, and must be overcome by the progress of perception and thought.
