These three volumes would be so generally interesting, so exceedingly entertaining, that you might bid fair for a sale of the work at large. Then let the fourth volume take up the history of metaphysics, theology, medicine, alchemy, common, canon, and Roman law, from Alfred to Henry VII.; in other words, a history of the dark ages in Great Britain. The fifth volume--carry on metaphysics and ethics to the present day in the first half; the second half, comprise the theology of all the reformers. In the fourth volume there would be a grand article on the philosophy of the theology of the Roman Catholic religion. In this (fifth volume), under different names,--Hooker, Baxter, Biddle, and Fox,--the spirit of the theology of all the other parts of Christianity. The sixth and seventh volumes must comprise all the articles you can get, on all the separate arts and sciences that have been treated of in books since the Reformation; and, by this time, the book, if it answered at all, would have gained so high a reputation, that you need not fear having whom you liked to write the different articles--medicine, surgery, chemistry, etc., etc., navigation, travellers, voyagers, etc., etc. If I go into Scotland, shall I engage Walter Scott to write the history of Scottish poets? Tell me, however, what you think of the plan. It would have one prodigious advantage: whatever accident stopped the work, would only prevent the future good, not mar the past; each volume would be a great and valuable work "per se". Then each volume would awaken a new interest, a new set of readers, who would buy the past volumes of course; then it would allow you ample time and opportunities for the slavery of the catalogue volumes, which should be at the same time an index to the work, which would be, in very truth, a pandect of knowledge, alive and swarming with human life, feeling, incident. By the bye, what a strange abuse has been made of the word encyclopaedia! It signifies, properly, grammar, logic, rhetoric, and ethics and metaphysics, which last, explaining the ultimate principles of grammar--log., rhet., and eth.--formed a circle of knowledge. * * * To call a huge unconnected miscellany of the "omne scibile", in an arrangement determined by the accident of initial letters, an encyclopaedia, is the impudent ignorance of your Presbyterian bookmakers. Good night!
