Priestley is for having men refer all the good in the universe to God as the author of it, and all the evil that takes place to man or to second causes. I cannot think that this is sound philosophy nor practical wisdom. The necessarians have evidently borrowed their notions of agency and second causes from the advocates for liberty: for taking up the same unfounded assumption of the libertarians, that action is the absolute beginning of motion, and that any thing short of this is no action at all, and finding that the will was not a cause in the absurd sense supposed by their adversaries, they have concluded that it was no cause at all; not considering whether a cause might not be more properly defined that which produces an effect in consistency with other things than that which produces it independently of them. Action then in any sense of the word is the same as co-operation. It may be asked, whether this account does not destroy the distinction between active and passive. I answer that it does, if by active be meant unconnected action, and by passive connected action; but not else. That is, if by action be understood the positive determinate tendency or the additional impulse to the production of any effect, and by passiveness an indifference in any agent to this or that motion, except as it is acted upon by, and transmits the efficacy of other causes, this distinction will remain as broad and palpable as ever. Any thing is so far active as it modifies and re-acts upon the original impulse; it is passive in as far as it neither adds to, nor takes from that original impulse, but merely has a power of receiving and continuing it. This I take to be the practical and philosophical meaning of the terms. This distinction therefore, applies equally to matter and mind. The explosion of gunpowder cannot be attributed entirely or principally to the spark which ignites it, because the effect is increased a thousand-fold by the inherent qualities of the gunpowder. The motion communicated by one body to another in void space is considered as the mere passive result of the former, because the effect in the second agent is simply the continuation of what it was in the first. So it is in the mind. Motives do not act upon it simply or absolutely; but according to the dictates of the understanding or the bias of the will. At one time we yield to any idle inclination that happens to prevail, and at others resist to the utmost the strongest motives. That is, the mind is itself an agent, one chief determining cause of our volitions. It is on the view taken by the mind of motives, on our disposition to attend to or neglect them, to compare and weigh them, that their effect depends. But the necessarians have always delighted to illustrate the operations of the mind in volition by referring to the impulse communicated by one billiard-ball to another, or to different weights in a pair of scales. Both which
