In all this, Vico is not only a thorough revolutionary, but is quite conscious of being so: he knows himself to be in opposition to all previous theories on the subject. He says that his new principles of poetry "are wholly opposed to, and not merely different from, all which have been imagined from the time of Plato and his disciple Aristotle to Patrizzi, Scaliger and Castelvetro among the moderns; poetry is now discovered to have been the first language used by all nations alike, even the Hebrew."[30] In another passage he says that by his theories "is overthrown all that has ever been said of the origin of poetry, beginning from Plato and Aristotle, right down to our own Patrizzi, Scaliger and Castelvetro; and it is found that poetry arising through defect of human ratiocination is as sublime as any which owes its being to the later rise of philosophy and the arts of composition and criticism; indeed, that these later sources never gave rise to any poetry that could equal, far less surpass it."[31] In the Autobiography he boasts of having discovered "other principles of poetry than those found by Greeks and Latins and all others from those times down to the present day; on these are founded other views on mythology."[32] These ancient principles of poetry "laid down first by Plato and confirmed by Aristotle" had been the anticipation or prejudice which had misled all writers on poetic reason (among whom he cites Jacopo Mazzoni). Statements "even of most serious philosophers such as Patrizzi and others" upon the origin of song and verse are so inept that he "blushes even to mention them."[33] It is curious to see him annotating the _Ars Poetica_ of Horace, with a view to finding some plausible sense in it by applying the principles of the _Scienza nuova_.[34] It is probable that he was familiar with the writings of Muratori among contemporaries, for he quotes him by name, and of Gravina, who was a personal acquaintance; but if he read the _Perfetta Poesia_ and the _Forza della fantasia_ he could not have been satisfied by the treatment meted out to the faculty of imagination, so highly valued and respected by himself; and if Gravina influenced him at all it must have been by provoking him to contradiction. In this latter (if not directly in such French writers as Le Bossu) he may have met with the fallacy of regarding Homer as a repository of wisdom, a fallacy which he combated with vigour and pertinacity. In his estimation, among the gravest faults of the Cartesians was their inability to appreciate the world of imagination and poetry. Of his own times he complained they were "benumbed by analytical methods and by a philosophy which sought to deaden every faculty of soul which reached it through the body, especially that of imagination, now held to be mother of all human error": times "of a wisdom which freezes the generous soul of the best poetry," and prevents all understanding of it.[35]
