See Dissertation II. Of the Nature of Virtue appended to the Analogy. It may be interesting to notice a gradual change in Butler's view on this important point. In the first of his Sermons on Human Nature, published some years before the Analogy, be does not notice, any more than Shaftesbury and Hutcheson, any possible want of harmony between Conscience and Benevolence. A note to Sermon XII., however, seems to indicate a stage of transition between the view of the first Sermon and the view of the Dissertation.
