‘As I consider’, wrote Smith to his London publishers in March 1788, ‘my tenure of this life as extremely precarious, and am very uncertain whether I shall live to finish several other works which I have projected and in which I have made some progress, the best thing, I think, I can do is to leave those I have already published in the best and most perfect state behind me.’ In the same letter, cited above, he notes that the additions and corrections for the new edition of The Theory of Moral Sentiments will be sent in three months. But as we see in the next letter also cited above, which was sent to Cadell a year later, Smith has discarded his initial plan to insert, after the fifth part, ‘a compleat new sixth part containing a practical system of Morality, under the title of the Character of Virtue.’ He only suggests, as to his change of mind, that ‘the subject has grown upon me.’
