Hume Studies

276 THE WILL AS IMPRESSION Hume writes, in the Treatise: Let no one, therefore, put an invidious construction on my words, by saying simply, that I assert the necessity of human actions, and place them on the same footing with the operations of senseless matter. I do not ascribe to the will that unintelligible necessity, which is suppos'd to lie in matter. But I ascribe to matter, that intelligible quality, call it necessity or not, which the most rigorous orthodoxy does or must allow to belong to the will. I^ change, therefore, nothing in the receiv'd systems, with regard to the will, but only with regard to material objects. It is surely false that Hume changed "nothing in the receiv'd systems, with regard to the will." In one such "receiv'd system," that of Thomas Aquinas, the concept of will or volition is presented as internally related to two further concepts: that of the "final cause" or goal of the action, and that of "practical intellect," a form of cognition which is productive of its object. Will is always the will to something, a goal to be reached or a product to be produced. Thus will and final cause are concepts which presuppose one another. The mark, however, of the fact that someone wills to do something, i.e., that s/he in fact has some goal, is precisely that that agent knows, non-inductively and without observation, what s/he is doing or will do. The basis of this knowledge is neither evidence nor proof, but rather what Aristotle called "the practical syllogism." We will ask below what it means to describe the relationships among will, final cause, and practical knowledge as 'internal.' 277 The question to be explored here is this: what in fact becomes of the 'receiv'd concept of will' when one contends, in the empiricist spirit common to both Locke and Hume, that all of our knowledge about matters of fact is based on observation and induction? The answer to this question will turn out to be that, in the absence of a notion of "practical knowledge," the concept of final cause becomes unintelligible (since the final cause is precisely the object of practical knowledge); and thus the notion of will must be reconstrued, for Hume as an impression. As an impression it is a brute given, one that is furthermore mute (or lacking in propositional content). Hume views volition as an event, that object of inner experience which is the (Humean) cause of our voluntary actions. In what follows I shall first of all sketch Thomas Aquinas' view of the will (section I), following this with a discussion of the important hybrid view in Locke's Essay, where older notions of volition are presented within an incompatible epistemological framework. In section III we look at Hume's sharp response to Locke, and in section IV at his own doctrine of the will as impression. In the final section I attempt to distinguish two strands of causality in Hume's philosophy of human action, drawing at the same time a moral for the contemporary dispute about reasons and causes. One of the most fully developed of the "receiv'd systems with regard to the will" was that of St. Thomas Aquinas, who combined Neo-Platonist, Patristic, and Aristotelian sources into an 2 impressive and influential synthesis. Thomas' 278 doctrine on the will is guided by a Grand Analogy, one inspired by the Creation story in Genesis. He writes, at the beginning of the second main part of his Summa : Man is made to God's image, and since this implies . . . that he is intelligent and free to judge and master of himself, so then, now that we have agreed [in part one of the Summa] that God is the exemplar cause of things and that they issue from his power through his will, we go on to look at this image, that is to say, at man as the source of actions which are his own and fall under his responsibility and control. The analogy is this: God, the Divine Craf tsperson, is to the Creation as human agents are to their...
