in all their profound divergencies and contradictions the modes of feeling and thought proper to various times. The great effort which had to be made, and actually was made by Vico, in order to penetrate through modern intellectualism and recapture the point of view of primitive psychology, is expressed in his language about the "grave difficulties" entailed by his "labour of fully twenty-five years" in the attempt to "stoop from these civilised natures of ours to those absolutely wild and savage minds, which we cannot picture to ourselves at all, and can only understand with great toil." It is expressed again, rather differently, by his insistence on the impossibility, now that, even with the common people, the mind of man is too completely separated from the senses, accustomed to the free use of abstract terms, sharpened by the art of writing, and spiritualised so to speak by the employment of numbers,--the impossibility of entering into the chaotic fancy of primitive man, whose mind was the very reverse of abstract, acute or spiritual; but rather sunk in the senses, blunted by passion, and buried in the body: and of grasping such ideas as that of the "sympathy of nature." This necessary effort--a painful one, but successful--was another reason for his feeling that his science was "new." He says indeed that this study of the ideal form and the historic period of certitude was entirely lacking to Greek philosophy as a whole. Plato had attempted it in the _Cratylus,_ but unsuccessfully, because he knew nothing of the language of the first legislators, the heroic poets, and was deceived by the altered and modernised forms under which the laws existed in his time after continual revision at Athens. Among the moderns, J. C. Scaliger, Francisco Sanchez and Gaspar Schopp had fallen into a similar mistake when they attempted to explain language by the principles of logic, and indeed of Aristotelian logic, in spite of its having arisen centuries after language itself. Grotius, Selden, Puffendorf and the other writers on natural rights also studied human nature as civilised by religion and law; so that in retracing the course of history they began in the middle: that is to say, they confined themselves to the intellect, ignoring the imagination, and to the will under moral restraint, passing over the undisciplined passions. Vico himself, while he had shown his interest in this problem by undertaking to investigate the "most ancient wisdom of Italy," was yet led astray in his study by following the lead of the author of the _Cratylus._ In its philosophical aspect, the New Science might, owing to this prominence given to the study of the individualising forms, above all the imagination (since the doctrine that primitive man is a poet and thinks in poetic images is in Vico's words the "master key" of the work) be called, without undue paradox, a philosophy of Mind with special attention to the Philosophy of Imagination or Aesthetic.
