Vico is indeed a revolutionary, a pioneer. He knows very well that he is in direct opposition to all that has been thought before about poetry. "My new principles of poetry upset all that first Plato and then Aristotle have said about the origin of poetry, all that has been said by the Patrizzi, by the Scaligers, and by the Castelvetri. I have discovered that It was through lack of human reason that poetry was born so sublime that neither the Arts, nor the Poetics, nor the Critiques could cause another equal to it to be born, I say equal, and not superior." He goes as far as to express shame at having to report the stupidities of great philosophers upon the origin of song and verse. He shows his dislike for the Cartesian philosophy and its tendency to dry up the imagination "by denying all the faculties of the soul which come to it from the body," and talks of his own time as of one "which freezes all the generous quality of the best poetry and thus precludes it from being understood." As regards grammatical forms, Vico may be described as an adherent of the great reaction of the Renaissance against scholastic verbalism and formalism. This reaction brought back as a value the experience of feeling, and afterwards with Romanticism gave its right place to the imagination. Vico, in his _Scienza nuova_, may be said to have been the first to draw attention to the imagination. Although he makes many luminous remarks on history and the development of poetry among the Greeks, his work is not really a history, but a science of the spirit or of the ideal. It is not the ethical, logical, or economic moment of humanity which interests him, but the _imaginative_ moment. _He discovered the creative imagination_, and it may almost be said of the _Scienza nuova_ of Vico that it is Aesthetic, the discovery of a new world, of a new mode of knowledge. This was the contribution of the genius of Vico to the progress of humanity: he showed Aesthetic to be an autonomous activity. It remained to distinguish the science of the spirit from history, the modifications of the human spirit from the historic vicissitudes of peoples, Aesthetic from Homeric civilization. But although Goethe, Herder, and Wolf were acquainted with the _Scienza nuova_, the importance of this wonderful book did not at first dawn upon the world. Wolf, in his prolegomena to Homer, thought that he was dealing merely with an ingenious speculator on Homeric themes. He did not realize that the intellectual stature of Vico far surpassed that of the most able philologists.
