Coleridge's _Biographia Literaria_, in which the principal so-called Schelling plagiarisms are contained, was published in 1817, but it was not for a considerable time after that that the plagiarisms were discovered, or at least taken notice of. The first serious indictment came from no less an authority than De Quincey, whose interest in philosophical matters was as great as Coleridge's, and who published his views in an appreciative but gossipy article in _Tait's Magazine_ of September 1834. To commence with, he took up the question of the 'Hymn to Chamouni'; but since, in this matter, Coleridge afterwards admitted his indebtedness to a German poetess, Frederica Brun, it does not seem an important one. Nor, indeed, does De Quincey pretend to take exception to certain expressions in Coleridge's 'France' which are evidently borrowed from Milton, or to regard them as indicating more than a peculiar omission of quotation marks. But the really serious matter, one for which De Quincey cannot by any means account, is that in the _Biographia Literaria_ there occurs a dissertation on the doctrine of Knowing and Being which is an exact translation from an essay written by Schelling. De Quincey cannot indeed explain away the mystery, but he makes the best of it, pleading excuses such as we often hear adduced in cases of 'kleptomania' when they occur amongst the well-to-do, or so-called higher classes--_e.g._, the evident fact that there was no necessity so to steal, no motive for stealing, even though the theft had evidently been committed. Still, though the defence may be ingenious, and though we may go so far as to acknowledge that Coleridge had sufficient originality of mind to weave out theories of his own without borrowing from others, it must be confessed that under the aggravated circumstances the argument falls somewhat flat; and this was the impression made on many minds even at the time. The ball once set rolling, the dispute went on, and the next important incident was an article by Julius Hare in the _British Magazine_ of January 1835. This is a hot defence of the so-called 'Christian' philosopher, who is said to be influencing the best and most promising young men of the day, as against the assault of the 'English Opium-Eater'--'that ill-boding _alias_ of evil record.' As to De Quincey's somewhat unkind but entertaining stories, there is some reason in Hare's objections, seeing that they were told of one to whom the writer owned himself indebted. But when Hare tackles the plagiarisms themselves, and endeavours to defend them, his task is harder. Coleridge had indeed stated that his ideas were thought out and matured before he had seen a page of Schelling; but at the same time, in an earlier portion of his work, he made a somewhat ambiguous reference to his indebtedness to the German philosopher, and deprecated his being accused of intentioned plagiarism from his writings. Of course it may be said that a thief
