The principle that _all the ideas, operations, and faculties of the mind may be traced to, and ultimately accounted for, from simple sensation_, is all that remains of Mr. Locke’s celebrated Essay, and that to which it owes its present rank among philosophical productions. His various attempts to modify this principle, or reconcile it to common notions have been gradually exploded, and have given place, one by one, to the more severe and logical deductions of Hobbes from the same general principle. Mr. Locke took the faculties of the mind as he found them in himself and others, and instead of levelling the structure, was contented to place it on a new foundation. By this compromise with prudence and candour, he prepared the way for the introduction of the principle, which being once established, very soon overturned all the trite opinions, and vulgar prejudices, which had been improperly associated with it. There was in fact, no place for them in the new system. I confess it strikes some degree of awe into the mind, and makes it feel, that fame, even the best, is not a substantial thing, but the uncertain shadow of real excellence, when we reflect that the immortal renown, which attends the name of Locke as the great luminary of the age in which he lived, is but a dim and borrowed lustre from the writings of one, whom he himself calls, and who has been universally considered as ‘a justly decried author.’ The sentence of the poet is as applicable here as it ever was— ‘Fame is no plant that grows on mortal soil, Nor in the glistering foil Set off to the world, nor in broad rumour lies; But lives and spreads aloft by those pure eyes, And perfect witness of all-judging Jove!’
