Our minds grasp only that which is objective in form. What concerns us most, though, is subjective in form. This fundamental agony of being is the root of the best and worst religion.
An object is that which exists side-by-side among other entities.
A subject is one who participates in a whole that wholly includes and exceeds himself.
A person: a subject and object, who relates as an object or subject to objects and subjects.
Both the objective and the subjective are violently reducible to the the terms of the other. One can inhabit a radically subjective world of extensionless phenomena. One can also inhabit a radically objective world as a being with emergent consciousness. Why, though?
