ABSTRACT
The typical factabout infant life is that it is unorganized, lacking in discrimination and orderly understanding and equally lacking in effective modes of behavior. As the individual matures, the elements of experience become organized into orderly forms. Consciousness becomes clear and definite. Behavior is well directed and efficient. The mental processes which appear under conditions of well-organized behavior are those which are ordinarily called “forms of knowledge.” Knowledge has two phases or aspects: content and arrangement, or form. Content comes from sensations and memories; arrangement, or form, comes from the patterns of central nervous association, which in turn direct behavior. Space and time are forms of experience. Colors, sounds, and tastes are contents.
