But, secondly, I conceive that the question does not stop here, because certain ideas have been annexed to these terms of liberty and necessity, both by the learned and by common men, which have nothing at all to do with the affirmation or denial of the simple connexion between cause and effect. What I shall therefore attempt will be to point out a few instances of the misapplication of the term to prove a necessity not included in the certainty of the event, and to disprove liberty in a sense in which it does not interfere with that certainty, or with philosophical necessity: that is, I shall attempt to show in what sense, in conformity with the general law to which all things are by their nature subject, man is an agent, a free agent, a moral and accountable agent; that is, deserving of reward and punishment, praise and blame, &c. Now by an agent I mean any thing that acts or has a power to operate, that is, to produce effects; by a free agent I mean one that is not hindered from acting; by a moral and accountable agent I mean one that acts from will, and is influenced by motives; by reward and punishment I mean what every one does; by praise and blame I mean our approbation or disapprobation of any agent that is conscious of our sentiments towards him, or that is capable of reflecting on his own conduct, and of being affected by what others think of it. If by an agent be meant the beginner of action, or one that produces an effect of itself, there can be no such thing; but if by an agent be meant one that contributes to an effect, there is such a thing as an agent; and the more any thing contributes to an effect and determines it to be this or that, the more it is an agent. If by freedom be meant a freedom from causes, or necessity in the abstract, there can be no freedom in this sense, but there may be and is a freedom from certain causes and from certain kinds and degrees of necessity; that is, from physical causes, or compulsion, and from absolute, unconditional necessity. If all things are equally necessary, that do not spring out of nothing, then indeed the distinction between liberty and necessity must be in all cases absurd. Again, by free-will I do not mean the power or liberty to act without motives, but with motives. The mind cannot act without an occasion or ground for acting, but this does not shew that it is no agent at all, or that it is not a free agent; that is, that its action is restrained or hindered by the action of anything else. The intellectual and voluntary powers are free, just as the corporeal are, namely, when they are free to produce certain effects, which, if excited, they can produce, as the body is free when it can move in consequence of the mind’s direction; it is no longer free when though the same reason exists for its moving, it is hindered by something else from obeying the impulse. In short, liberty is this: the power in any agent in given circumstances to operate in a certain manner, if left to
