Losing a belief in free will has not made me fatalistic-in fact, it has increased my feelings of freedom. My hopes, fears, and neuroses seem less personal and indelible. There is no telling how much I might change in the future. Just as one wouldn't draw a lasting conclusion about oneself on the basis of a brief experience of indigestion, one needn't do so on the basis of how one has thought or behaved for vast stretches of time in the past. A creative change of inputs to the system-learning new skills, forming new relationships, adopting new habits of attention-may radically transform one's life.
