of naturalism were hostile to the doctrine of imitation. The trend away from the doctrine of imitation towards emotional naturalism finds revolutionary expression in the literary field in such a work as Young’s “Conjectures on Original Composition” (1759). Addison had asserted, as we have seen, the superiority of what is original in a man, of what comes to him spontaneously, over what he acquires by conscious effort and culture. Young, a personal friend of Addison’s, develops this contrast between the “natural” and the “artificial” to its extreme consequences. “Modern writers,” he says, “have a choice to make. … They may soar in the regions of liberty, or move in the soft fetters of easy imitation.” “An original may be said to be of a vegetable nature; it rises spontaneously from the vital root of genius; it grows, it is not made; imitations are often a sort of manufacture, wrought up by those mechanics, art and labor, out of preëxistent materials not their own.” “We may as well grow good by another’s virtue, or fat by another’s food, as famous by another’s thought.” One evidence that we are still living in the movement of which Young is one of the initiators is that his treatise will not only seem to most of us a very spirited piece of writing--that it certainly is--but doctrinally sound. And yet it is only one of those documents very frequent in literary history which lack intrinsic soundness, but which can be explained if not justified as a recoil from an opposite extreme. The unsoundness of Young’s work comes out clearly if one compares it with the treatise on the “Sublime” attributed to Longinus which is not a mere protest against a previous excess, but a permanently acceptable treatment of the same problem of genius and inspiration. Longinus exalts genius, but is at the same time regardful of culture and tradition, and even emphasizes the relation between inspiration and the imitation of models. Young insinuates, on the contrary, that one is aided in becoming a genius by being brainless and ignorant. “Some are pupils of nature only, nor go further to school.” “Many a genius probably there has been which could neither write nor read.” It follows almost inevitably from these premises that genius flourishes most in the primitive ages of society before originality has been crushed beneath the superincumbent weight of culture and critics have begun their pernicious activities. Young did not take this step himself, but it was promptly taken by others on the publication of the Ossianic poems (1762). Ossian is at once added to the list of great originals already enumerated by Addison--Homer, Pindar, the patriarchs of the Old Testament and Shakespeare (whom Young like the later romanticists opposes to Pope). “Poetry,” says Diderot, summing up a whole movement, “calls for something enormous, barbaric and savage.”
