Although recognizing in a vague way the existence of genuine disinterested impulses, he dilates eloquently, and often, on the deliciousness of benevolence, and of all virtuous feelings and conduct.
The First Book of Paley's 'Moral and Political Philosophy' is entitled 'PRELIMINARY CONSIDERATIONS' it is in fact an unmethodical account of various fundamental points of the subject. He begins by defining Moral Philosophy as '_that science which teaches men their duty, and the reasons of it_. The ordinary rules are defective and may mislead, unless aided by a scientific investigation. These ordinary rules are the Law of Honour, the Law of the Land, and the Scriptures.
He commences with the Law of Honour, which he views in its narrow sense, as applied to people of rank and fashion. This is of course a very limited code.
The Law of the Land also must omit many duties, properly compulsory, as piety, benevolence, &c. It must also leave unpunished many vices, as luxury, prodigality, partiality. It must confine itself to offences strictly definable.
The Scriptures lay down general rules, which have to be applied by the exercise of reason and judgment. Moreover, they pre-suppose the principles of natural justice, and supply new sanctions and greater certainty. Accordingly, they do not dispense with a scientific view of morals.
[The correct arrangement of the common rules would have been (1) the Law of the Land, (2) the Laws of Society generally, and (3) the Scriptures. The Law of Honour is merely one application of the comprehensive agency of society in punishing men, by excommunication, for what it prohibits.]
Then follows his famous chapter on the MORAL SENSE.
It is by way of giving an effective statement of the point in dispute that he quotes the anecdote of Caius Toranius, as an extreme instance of filial ingratitude, and supposes it to be put to the wild boy caught in the woods of Hanover, with the view of ascertaining whether he would feel the sentiment of disapprobation as we do. Those that affirm an innate moral sense, must answer in the affirmative; those that deny it, in the negative.
He then recites the arguments on both sides.
For the moral sense, it is contended, that we approve examples of generosity, gratitude, fidelity, &c., on the instant, without deliberation and without being conscious of any assignable reason; and that this approbation is uniform and universal, the same sorts of conduct being approved or disapproved in all ages and countries; which circumstances point to the operation of an instinct, or a moral sense.
