 I consider the determination of the will as an effect. This effect must have a cause which had the power to produce it; and the cause must be either the person himself, whose will it is, or some other being…. If the person was the cause of that determination of his own will, he was free in that action, and it is justly imputed to him, whether it be good or bad. But, if another being was the cause of this determination, either producing it immediately, or by means and instruments under his direction, then the determination is the act and deed of that being, and is solely imputed to him. (1788 [1969] IV.i, 265)
