And whatever increases, decreases, limits, or extends the mind's power of action, also increases, decreases, limits, or extends the body's power of action.
In the realm of science, all attempts to find any evidence of supernatural beings, of metaphysical concepts, as God, immortality, infinity, etc have thus far failed, and if we are honest, we must confess that in science there exists no God, no immortality, no soul or mind, as distinct from the body.
