This objection does not seem to be well taken. When we say, that the will is the cause of any thing, we do not really mean that the will itself is the cause of it; for the will itself does not act: it is not an agent, it is merely the power of an agent. It is that power by which the mind acts. Hence, when the will is said to cause a thing, the language must either have no intelligible meaning, or it must be understood to mean, that the mind causes it by an exercise of its power of willing. But to say that the mind causes a thing by an exercise of its power of willing, is to say that it causes it by an act of the will or a volition; which brings us to the assumption of Edwards. Hence, if the language that "the will causes its own volitions" means any thing, it must mean what Edwards supposes it does. That is, if the will causes its volition, or rather, if the mind in the act of willing causes them, then they must be caused by volitions or acts of the will. It is said, that "we do not know _how_ any cause acts." This is very true, when properly understood; but in the true sense of this maxim, Edwards has not undertaken to explain how a cause acts; nor has he made any assumption as to how it acts. The _term_ cause has a variety of meanings; and it is frequently applied with extreme vagueness and want of precision. What is the cause of an effect?--of the motion of the hand, for example? It is the mind, says one; it is the will, says another; it is a volition, replies a third. Now here are three distinct things,--the mind, the will, and the volition; and yet each is said to be the cause of the same identical effect. This diversity of expression may do very well in popular discourse, but it must be laid aside whenever philosophical precision is required. What is then, really and properly speaking, the cause of the motion in question? It is neither the mind, nor the will; for these might both exist, and yet no such effect result from them. A mind, or a will, that lies still and does not act, is the cause of no effect. If we would speak with philosophical precision, then, we should say that the act of the mind is the cause of the effect in question. The idea of a cause, in the strict and proper sense of the term, is that from which the effect immediately and necessarily flows. Now the motion of the hand is not necessarily connected with the mind itself; for if the mind were to lie still and not act, no such effect would follow. It is with the act of the mind that the effect in question is connected as with its efficient cause. It is the act of the mind which implies the motion of the hand, and that is implied by it; and hence, it is the act of the mind, or the volition, that is properly said to be the cause of such motion. For cause and effect, are said to imply each other.
