3 categories of knowledge
     There are three kinds of perception. The first is faith, the second is reason, and the third kind of perception is experience.
     You use these kinds of perception as “tools” when you create and develop your “painting.” Faith starts the picture by determining what is central. Reason applies your faith to the different parts of life. Experience checks your picture against the real picture.
     These three kinds of perception create three categories of knowledge, roughly equivalent to religion, philosophy, and science. These kinds of knowledge relate, build on each other, and often seem to overlap.
