This document outlines the four stages in the apprehension of concepts: external perception, internal perception, abstraction, and judgment. External perception results in a percept, internal perception forms an image, abstraction derives a concept, and judgment produces a proposition. These stages describe the process of conceptualization from initial sensory input to a reasoned understanding.
