 Thus, to reiterate again, the three linguistic forms of substantive, adjective, and verb are required to express thought’s apprehension of (independent) objects, (dependent) properties, and relations (respectively). And for such formative purposes, syntax is critical, not sound. This is because “thought cannot directly make use of sensations, feelings, moods, simple or complex images, as materials for its structure” (Micro, I, p. 622).
