Dugald Stewart (1753-1828), philosophe écossais. L.A.S., Kinneil House (Bo'ness), 20 mai 1820, 3p in-4. Longue lettre en anglais à un autre philosophe écossais, William Hamilton (1788-1856), qui publiera d'ailleurs les oeuvres de Stewart en 1854-1855. « My dear Sir William, You will oblige me much if you will take the trouble to enquire whether the Advocates Library possesses a Book with the following title : Clavis Universalis : or a new inquiry after truth. Being a demonstration of the non-existence, or Impossibilité of an external world. Bu Arthur Collier, Rector of Langford Magna, near Sarum (London, printed for Robert Gosling, at the Mitre and Crown, against St. Dunstan's Chruch in Fleetstreet 1713) . I had an opportunity of reading this book (which I understand is now extremely rare) when I was last in England ; but I should wish to have it again in my possession for a few days. From a passage in T. Reid's Essays on The Intellectual Powers, p.173 4th edit., it appears that there is a copy of it in the Library of the University of Glasgow. If it is not to be found in any of the public Librairies at Edimburgh, will you have the goodness to mention it to any of the Glasgow professors who may be in town at present & who, I doubt not, will be kind enough to favor me with a [mot illisible] loan of it. It si remarkable that the name of Collier (who seems to have been a most ingenious man) is not to be found in any [mot illisible] biographical dictionaries ; nor gave I ever been able to procure the slightest information concerning him. If you have met, or should hereafter met, in the course of your reading, with any particulars relating to himself or his printings, you will do me a favour of communicating them. All this may be done at your [mot illisible], as I am in no particular hurry at present. I am ancious tu hear, if you have yet received the letters you expected from Oxford. They appear to me of great consequence at the present moment. I hope tu hear from you or to see you soon. In the mean time, I remain, with the most cordial wishes for your success, my dear sir William, yours most truly, Dugald Stewart. Our accounts from Switzerland by this days past, are much more comfortable ». Cachet de cire, adresse sur la quatrième page, petit manque en marge dû au cachet. Belle lettre. [184]
