Now, you receive all your ideas; therefore you receive your wish, you wish therefore necessarily. The word "liberty" does not therefore belong in any way to your will....The will, therefore, is not a faculty that one can call free. A free will is an expression absolutely void of sense, and what the scholastics have called will of indifference, that is to say willing without cause, is a chimera unworthy of being combated.
