paragraph are founded only on conjecture and analogy."[120] Throughout his whole work the scarcity of materials forces Gibbon to the frequent use of conjecture, but I believe that for the most part his conjectures seem reasonable to the critics. Impressed with the correctness of his account of the Eastern empire a student of the subject once told me that Gibbon certainly possessed the power of wise divination. Gibbon's striving after precision and accuracy is shown in some marginal corrections he made in his own printed copy of "The Decline and Fall." On the first page in his first printed edition and as it now stands, he said, "To deduce the most important circumstances of its decline and fall: a revolution which will ever be remembered and is still felt by the nations of the earth." For this the following is substituted: "To prosecute the decline and fall of the empire of Rome: of whose language, religion, and laws the impression will be long preserved in our own and the neighboring countries of Europe." He thus explains the change: "Mr. Hume told me that, in correcting his history, he always labored to reduce superlatives and soften positives. Have Asia and Africa, from Japan to Morocco, any feeling or memory of the Roman Empire?" On page 6, Bury's edition, the text is, "The praises of Alexander, transmitted by a succession of poets and historians, had kindled a dangerous emulation in the mind of Trajan." We can imagine that Gibbon reflected, What evidence have I that Trajan had read these poets and historians? Therefore he made this change: "Late generations and far distant climates may impute their calamities to the immortal author of the Iliad. The spirit of Alexander was inflamed by the praises of Achilles; and succeeding heroes have been ambitious to tread in the footsteps of Alexander. Like him, the Emperor Trajan aspired to the conquest of the East."[121] The "advertisement" to the first octavo edition published in 1783 is an instance of Gibbon's truthfulness. He wrote, "Some alterations and improvements had presented themselves to my mind, but I was unwilling to injure or offend the purchasers of the preceding editions." Then he seems to reflect that this is not quite the whole truth and adds, "Perhaps I may stand excused if, amidst the avocations of a busy winter, I have preferred the pleasures of composition and study to the minute diligence of revising a former publication."[122]
