Starting from the base of conceptual development—from the concepts that
identify perceptual concretes—the process of cognition moves in two
interacting directions: toward more extensive and more intensive knowledge,
toward wider integrations and more precise differentiations. Following the
process and in accordance with cognitive evidence, earlier-formed concepts are
integrated into wider ones or subdivided into narrower ones.
