Chapter Vi. Is on the Cases Where the Sense of Duty Should Be the Sole

motive of conduct; and on those where it ought to join with other motives. Allowing the importance of religion among human motives, he does not concur with the view that would make religious considerations the sole laudable motives of action. The sense of duty is not the only principle of our conduct; it is the ruling or governing one. It may be a question, however, on what occasions we are to proceed strictly by the sense of duty, and on what occasions give way to some other sentiment or affection. The author answers that in the actions prompted by benevolent affections, we are to follow out our sentiments as much as our sense of duty; and the contrary with the malevolent passions. As to the selfish passions, we are to follow duty in small matters, and self-interest in great. But the rules of duty predominate most in cases where they are determined with exactness, that is, in the virtue of Justice.
