If the Will is not free, the idea of Liberty is wholly inapplicable to any phenomenon in existence whatever. Yet this idea is in the mind. The action of the Will in conformity to it is just as conceivable as its action in conformity to the idea of Necessity. It remains with the Necessitarian to account for the existence of this idea in the human mind, in consistency with his own theory. Here the following considerations present themselves demanding special attention.
1. The idea of Liberty, like that of Necessity, is a simple, and not a complex idea. This all will admit.
2. It could not have come into the mind from observation or reflection because all phenomena, external and internal, all the objects of observation and reflection, are, according to the doctrine of Necessity, not free, but necessary.
3. It could not have originated, as necessary ideas do, as the logical antecedents of the truths given by observation and reflection. For example, the idea of space, time, substance, and cause, are given in the Intelligence, as the logical antecedents of the ideas of body, succession, phenomena, and events, all of which are truths derived from observation or reflection. Now the idea of Liberty, if the doctrine of Necessity is true, cannot have arisen in this way because all the objects of observation and reflection are, according to this doctrine, necessary, and therefore their logical antecedents must be. How shall we account, in consistency with this theory, for the existence of this idea in the mind? It came not from perception external, nor internal, nor as the logical antecedent or consequent of any truth thus perceived. Now if we admit the doctrine of Liberty as a truth of universal consciousness, we can give a philosophical account of the existence of the idea of Liberty in all minds. If we deny this doctrine, and consequently affirm that of Necessity, we may safely challenge any theologian or philosopher to give such an account of the existence of that idea in the mind. For all ideas, in the mind, do and must come from observation or reflection, or as the logical antecedents or consequents of ideas thus obtained. We have here an event without a cause, if the doctrine of Necessity is true.
4. All simple ideas, with the exception of that of Liberty, have realities within or around us, corresponding to them. If the doctrine of Necessity is true, we have one solitary idea of this character, that of Liberty, to which no reality corresponds. Whence this solitary intruder in the human mind?
The existence of this idea in the mind is proof demonstrative, that a reality corresponding to it does and must exist, and as this reality is found nowhere but in the Will, there it must be found. Almost all Necessitarians are, in philosophy, the disciples of Locke. With him, they maintain, that all ideas in the mind come from observation and reflection. Yet they maintain that there is in the mind one idea, that of Liberty, which never could thus have originated; because, according to their theory, no objects corresponding do or can exist, either as realities, or as the objects of observation or reflection. We have again an event without a cause, if the doctrine of Liberty is not true.
5. The relation of the ideas of Liberty and Necessity to those of obligation, merit and demerit, &c., next demand our attention. If the doctrine of Necessity is true, the idea of Liberty is, as we have seen, a chimera. With it the idea of obligation can have no connection or alliance; but must rest exclusively upon that of Necessity. Now, how happens it, that no man holding the doctrine of Liberty was ever known to deny that of obligation, or of merit and demerit? How happens it, that the validity of neither of these ideas has ever, in any age or nation, been denied, except on the avowed authority of the doctrine of Necessity? Sceptics of the class who deny moral obligation, are universally avowed Necessitarians. We may safely challenge the world to produce a single exception to this statement. We may challenge the world to produce an individual in ancient or modern times who holds the doctrine of Liberty, and denies moral obligation, or an individual who denies moral obligation on any other ground than that of Necessity. Now, how can this fact be accounted for, that the ideas of obligation, merit and demerit, &c., universally attach themselves to a chimera, the idea of Liberty, and stand in such irreconcilable hostility to the only idea by which, as Necessitarians will have it, their validity is affirmed?
6. Finally, If the doctrine of Necessity is true, the phenomena of the Intelligence, Sensibility, and the Will, are given in Consciousness as alike necessary. The idea of Liberty, then, if it does exist in the mind, would not be likely to attach itself to either of these classes of phenomena; and if to either, it would be just as likely to attach itself to one class as to another. Now, how shall we account for the fact, that this idea always attaches itself to one of these classes of phenomena, those of the Will, and never to either of the others? How is it that all men agree in holding, that, in the circumstances of their occurrence, the phenomena of the Intelligence and Sensibility cannot but be what they are, while those of the Will may be otherwise than they are? Why, if this chimera, the idea of Liberty, attaches itself to either of these classes, does it not sometimes attach itself to the phenomena of the Intelligence or Sensibility, as well as to those of the Will? Here, once again, we have an event without a cause, a distinction without a difference, if the doctrine of Necessity is true. The facts before us can be accounted for only on the supposition, that the phenomena of the Intelligence and Sensibility are given in Consciousness as necessary, while those of the Will are given as free.

IV. We will now, in the fourth place, raise the inquiry, an inquiry very appropriate in its place, and having an important bearing upon our present investigations, whether the doctrine of the Will, above established, is the doctrine pre-supposed in the Bible? The following considerations will enable us to give a decisive answer to this inquiry.
