Romanticism, then, although it has its epochs, [257] is in its essential characteristics rather a spirit which shows itself at all times, in various degrees, in individual workmen and their work, and the amount of which criticism has to estimate in them taken one by one, than the peculiarity of a time or a school. Depending on the varying proportion of curiosity and the desire of beauty, natural tendencies of the artistic spirit at all times, it must always be partly a matter of individual temperament. The eighteenth century in England has been regarded as almost exclusively a classical period; yet William Blake, a type of so much which breaks through what are conventionally thought the influences of that century, is still a noticeable phenomenon in it, and the reaction in favour of naturalism in poetry begins in that century, early. There are, thus, the born romanticists and the born classicists. There are the born classicists who start with form, to whose minds the comeliness of the old, immemorial, well-recognised types in art and literature, have revealed themselves impressively; who will entertain no matter which will not go easily and flexibly into them; whose work aspires only to be a variation upon, or study from, the older masters. "'Tis art's decline, my son!" they are always saying, to the progressive element in their own generation; to those who care for that which in fifty years' time every one will be caring for. On the other hand, there are the born romanticists, who start with an original, [258] untried matter, still in fusion; who conceive this vividly, and hold by it as the essence of their work; who, by the very vividness and heat of their conception, purge away, sooner or later, all that is not organically appropriate to it, till the whole effect adjusts itself in clear, orderly, proportionate form; which form, after a very little time, becomes classical in its turn.
