The New Science, agreeably to the various meanings of the terms philosophy and philology and of the relation between them, consists of three groups of investigations, philosophical, historical and empirical. Altogether it contains a philosophy of mind, a history, or group of histories, and a social science. To the first named belong the ideas expressed in various axioms or aphorisms scattered up and down the work, on imagination and the imaginative universal, on the intellect and the logical universal, on myth, religion, the moral judgment, force and law, certitude and truth, the passions, providence, and all the other determinations affecting the course or development of the thought or mind of man. To the second, namely history, belong the sketch of a universal history of primitive peoples from the time of the Flood, and of the origins of the various civilisations: the description of the ancient barbaric or heroic society in Greece and especially in Rome, with regard to religion, customs, law, language and political constitution: the study of primitive poetry, concentrating upon the determination of the genesis and character of the Homeric poems: the history of the social struggles between the patricians and plebeians and the origin of democracy, also studied chiefly in Rome: and the description of the return of barbarism or the Middle Ages, also studied in all aspects of life and compared with primitive barbaric society. Finally, to empirical science belongs the attempt to establish a uniform course of national history, dealing with the succession both of political forms and of other correlative manifestations of life both theoretical and practical, and the series of types successively drawn by Vico of the patriciate, the plebs, feudalism, the patriarchal family, symbolic law, metaphorical language, hieroglyphic writing and so forth.
