Is There a Causation of the Will?

The question is ultimately whether we will really realise the will is operating. If we do so, and fundamentally our belief in this is just our belief in causality itself, we must make the attempt to posit hypothetically the causality of the will as the only causality. Will can naturally only operate on will and not on matter, not on nerves for instance. In short, the hypothesis must be hazarded, whether will does not operate on will, wherever effects are recognised,. And whether all mechanical action, inasmuch as a power operates therein, is not just the power of will, the effect of will.
