That which you call your soul or spirit is your consciousness, and that which you call 'free will' is your mind's freedom to think or not, the only will you have, your only freedom, the choice that controls all the choices you make and determines your life and your character.
Ayn RandOur dearest one. Fear nothing of the forest. There is no danger in solitude. We have no need of our brothers. Let us forget their good and our evil, let us forget all things save that we are together and that there is joy as a bond between us. Give us your hand. Look ahead. It is our own world, Golden One, a strange, unknown world, but our own.
Ayn RandPsychologically, the choice "to think or not" is the choice "to focus or not." Existentially, the choice "to focus or not" is the choice "to be conscious or not." Metaphysically, the choice "to be conscious or not" is the choice of life or death.
