Abstract
It may be that Kant manifested a profound understanding of modern empirical science in his observation that we have now placed nature on the witness stand and are compelling her to answer the questions we think fit to propose. This, I am convinced, is not the approach best suited to bring out the deepest insights and systematic teachings of another philosopher. On the contrary, it would seem that one can make sense out of another man's thought only by coming to know how that person sees the problem, and what he regards as an adequate solution to it. If this is correct, one of our first objectives should be to see how Weiss sees the problem of knowledge and what he regards as the requirements for an adequate account of human knowledge.
