In this connection he more than once appeals to the doctrine of Fichte, one of the few writers whom he was willing to recognize as his teachers. "According to Fichte, there is a 'divine idea' pervading the visible universe; which visible universe is indeed but its symbol and sensible manifestation, having in itself no meaning, or even true existence independent of it. To the mass of men this divine idea of the world lies hidden; yet to discern it, to seize it, and live wholly in it, is the condition of all genuine virtue, knowledge, freedom; and the end, therefore, of all spiritual effort in every age. Literary men are the appointed interpreters of this divine idea; a perpetual priesthood, we might say, standing forth, generation after generation, as the dispensers and living types of God's everlasting wisdom, to show it in their writings and actions, in such particular form as their own particular times require it in. For each age, by the law of its nature, is different from every other age, and demands a different representation of the divine idea, the essence of which is the same in all; so that the literary man of one century is only by mediation and reinterpretation applicable to the wants of another." [Footnote: Ib., p. 69. There is a similar passage in the _Lectures on Heroes_ (Lec. v.), p. 145. In each case the reference is to Fichte's Lectures _Ueber das Wesen des Gelehrten_ (1805), especially to lectures i., ii., and x,; Fichte's Werke, vi. 350-371, 439-447.] The particular form of Fichte's teaching may still sound unfamiliar enough. But in substance it has had the deepest influence on the aims and methods of criticism; and, so far as England is concerned, this is mainly due to the genius of Carlyle. Compare the criticism of the last century with that of the present, and we at once see the change that has come over the temper and instincts of Englishmen in this matter.
