As beings in the world, we feel (regardless of what the actual case might be) that this existence is open-ended: options exist, and different paths could be materialized or realized.
Maybe what we feel as free will is the possibilities themselves, appearing from inside a conscious being? In mind and imagination, we have the quality of pure and truly free potential. If there is an agent there (whether it exists in itself, is constructed, or is only a name), one we can call spirit, there are many paths it can take, and many options are available to it.
At the same time, it feels like we are trapped in the material world of pure necessity. This is why the notion of determinism resonates in our reasoning, the feeling that we can’t do otherwise, that we are prisoners and observers of our destiny. Only one path appears to materialize, out of necessity. Only one world is and will be real.
Are all sensations and freedom the potentiality itself, trapped inside the necessity of the body and the world? It might be the one eternal being expressing or playing itself throughout the various instances of pure potential. Still, a deeper question remains: why would the eternal being want to play? Is it out of free will or out of necessity?
