T 3.3.6.3

Were it proper in such a subject to bribe the readers assent, or employ any thing but solid argument, we are here abundantly supplied with topics to engage the affections. All lovers of virtue (and such we all are in speculation, however we may degenerate in practice) must certainly be pleas'd to see moral distinctions deriv'd from so noble a source, which gives us a just notion both of the generosity and capacity of humanour nature. It requires but very little knowledge of human affairs to perceive, that a sense of morals is a principle inherent in the soul, and one of the most powerful that enters into the composition. But this sense must certainly acquire new force, when reflecting on itself, it approves of those principles, from whence it is deriv'd, and finds nothing but what is great and good in its rise and origin. Those who resolve the sense of morals into original instincts of the human mind, may defend the cause of virtue with sufficient authority; but want the advantage, which those possess, who account for that sense by an extensive sympathy with mankind. According to theirthe latter system, not only virtue must be approv'd of, but also the sense of virtue: And not only that sense, but also the principles, from whence it is deriv'd. So that nothing is presented on any side, but what is laudable and good.
