Wesley’s stay in London was of short duration. On September 24, he left for Kingswood, where he spent a month in revising and preparing for the school the works following: Parochial Antiquities, by White Kennet, bishop of Peterborough; Grecian Antiquities, by Archbishop Potter; and Hebrew Antiquities, by Mr. Lewis. He also wrote, at this time, his “Short History of England,” and his “Short Roman History”; and nearly finished his abridgment of Cave’s Primitive Christianity, which he had begun about two years before. On October 24, he returned to London, and here, with the exception of short journeys to Windsor, Canterbury, and Leigh, he remained till the year was ended. His publications, during 1750, were as follows.— 1. “Desiderii Erasmi Colloquia Selecta. In Usum Juventutis Christianæ. Edidit Ecclesiæ Anglicanæ Presbyter.” 12mo, 85 pages. 2. “Phædri Fabulæ Selectæ. In Usum Juventutis Christianæ. Edidit Ecclesiæ Anglicanæ Presbyter.” 12mo, 35 pages. 3. “A Compendium of Logic.” 12mo, 33 pages. This was a translation of Dr. Henry Aldrich’s “Artis Logicæ Compendium. Oxon: 1691” [8vo]. “Logic,” says Wesley, “is the art of apprehending things clearly, judging truly, and reasoning conclusively. What is it, viewed in another light, but the art of learning and teaching; whether by convincing or persuading? What is there, then, in the whole compass of science, to be desired in comparison of it? It is good for this, at least (wherever it is understood), to make people talk less; by showing them both what is, and what is not, to the point; and how extremely hard it is to prove anything.”[105] It is well known, that Wesley himself was an adept in the art of logic. “For several years,” says he, “I was moderator in the disputations which were held six times a week at Lincoln College, in Oxford. I could not avoid acquiring hereby some degree of expertness in arguing; and especially in discerning and pointing out well covered and plausible fallacies. I have since found abundant reason to praise God for giving me this honest art. By this, when men have hedged me in by what they called demonstrations, I have been many times able to dash them in pieces; in spite of all its covers, to touch the very point where the fallacy lay; and it flew open in a moment.”[106] All the works, already mentioned, were chiefly designed for the use of Kingswood school. Those that follow were of a different kind.
