Yet we are not mere slaves to this situation, since we go to work on our current situation by glimpsing possibilities in it that we can try to actualize (future). Finally, every moment of factical life is a profound tension between what is given to us and how we confront it (present).
Life (n.) is a kind of unrest, forever torn between two poles of reality. Life is movement, or “motility.”
