It is impossible to exercise free will as long as we are operating from within the system. Free will requires consciousness, and our pervasive and deep-seated patterns of thought are unconscious; they are outside of our awareness and therefore outside of our control. While we remain in the system, we see the world through the eyes of carnism. And as long as we look through eyes other than our own, we will be living in accordance to a truth that is not of our own choosing. We must step outside the system to find our lost empathy and make choices that reflect what we truly feel and believe, rather than what we've been taught to feel and believe.
