Such is the force of natural temper, that these disappointments made little or no impression on me. I went down in 1749, and lived two years with my brother at his country-house, for my mother was now dead. I there composed the second part of my Essays, which I called Political Discourses, and also my Inquiry concerning the Principles of Morals, which is another part of my Treatise that I cast anew. Meanwhile, my bookseller A. Millar informed me, that my former publications (all but the unfortunate Treatise) were beginning to be the subject of conversation; that the sale of them was gradually increasing, and that new editions were demanded. Answers by Reverends, and Right Reverends, came out two or three in a year; and I found, by Dr Warburton's railing, that the books were beginning to be esteemed in good company. However, I had fixed a resolution, which I inflexibly maintained, never to reply to any body; and not being very irascible in my temper, I have easily kept myself clear of all literary squabbles. These symptoms of a rising reputation gave me encouragement, as I was ever more disposed to see the favourable than unfavourable side of things; a turn of mind which it is more happy to possess, than to be born to an estate of ten thousand a year. In 1751, I removed from the country to the town, the true scene for a man of letters. In 1752, were published at Edinburgh, where I then lived, my Political Discourses, the only work of mine that was successful on the first publication. It was well received abroad and at home. In the same year was published at London, my Inquiry concerning the Principles of Morals; which, in my own opinion (who ought not to judge on that subject), is of all my writings, historical, philosophical, or literary, incomparably the best. It came unnoticed and unobserved into the world.
