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.
