The author refers to Paley's Moral Philosophy as an example of the perverting tendency of narrow and domineering interests in the domain of ethics. With many commendable points, there is, in that work, much ignoble truckling to the dominant and influential few, and a deal of shabby sophistry in defending abuses that the few were interested in upholding. As a farther answer to the second objection, he remarks, that it applies to every theory of ethics that supposes our duties to be set by the Deity. Christianity itself is defective, considered as a system of rules for tho guidance of human conduct. He then turns to the alternative of a Moral Sense. This involves two assumptions. First, Certain sentiments, or feelings of approbation or disapprobation, accompany our conceptions of certain human actions. These feelings are neither the result of our reflection on the tendencies of actions, nor the result of education; the sentiments would follow the conception, although we had neither adverted to the good or evil tendency of the actions, nor become aware of the opinions of others regarding them. This theory denies that the sentiments known to exist can be produced by education. We approve and disapprove of actions _we know not why_. The author adapts Paley's supposition of the savage, in order to express strongly what the moral sense implies. But we will confine ourselves to his reasonings. Is there, he asks, any evidence of our being gifted with such feelings? The very putting of such a question would seem a sufficient proof that we are not so endowed. There ought to be no more doubt about them, than about hunger or thirst. It is alleged in their favour that our judgments of rectitude and depravity are immediate and voluntary. The reply is that sentiments begotten by association are no less prompt and involuntary than our instincts. Our response to a money gain, or a money loss, is as prompt as our compliance with the primitive appetites of the system. We begin by loving knowledge as a means to ends; but, in time, the end is inseparably associated with the instrument. So a moral sentiment dictated by utility, if often exercised, would be rapid and direct in its operation. It is farther alleged, as a proof of the innate character of the moral judgments, that the moral sentiments of all men are precisely alike. The argument may be put thus:--No opinion or sentiment resulting from observation and induction is held or felt by all mankind: Observation and induction, as applied to the same subject, lead different men to different conclusions. Now, the judgments passed internally on the rectitude or pravity of actions, or the moral sentiments, are precisely alike with all men. Therefore, our moral sentiments are not the result of our inductions of the tendencies of actions; nor were they derived from others, and impressed by authority and example. Consequently, the moral sentiments are instinctive, or ultimate and inscrutable facts.
