[filed under theme 12. Knowledge Sources / B. Perception / 2. Qualities in Perception / d. Secondary qualities ]

A Reaction

Nice question. Minds must have experiences, and there has to be a 'way' or 'mode' for those experiences. A mind which directly grasped the primary quality of sphericity would seem to be visionary rather than sensual or experiential.
