requisite to look out for some other Theory, that may be satisfactory; and I dare venture to affirm, that none such will ever be found, as long as we suppose Reason to be the sole Source of Morals. To prove this, it will be proper to weigh the five following Considerations.
I. 'Tis easy for a false Hypothesis to maintain some Appearance of Truth, while it keeps altogether in Generals, makes use of undefin'd Terms, and employs Comparisons, instead of Instances. This is particularly remarkable in that Philosophy, which ascribes the Discernment of all moral Distinctions to Reason alone without the Concurrence of Sentiment. 'Tis impossible, in any particular Instance, that this Hypothesis can so much as be render'd intelligible; whatever specious Figure it may make in general Declamations and Discourses. Examine the Crime of Ingratitude, for Instance; which has Place, wherever we observe Good-will, exprest and known, along with Good-offices perform'd, on the one Side, and a Return of Ill-will or Indifference, with Ill-offices or Neglect, on the other: Anatomize all these Circumstances, and examine, by your Reason alone, wherein consists the Demerit or Blame: You never will come to any Issue or Conclusion.
