Having reached, in his review of the course of history, his own time, a time of civilisation spread over all nations, Vico gives a rapid description of the contemporary world and then says no more: perhaps unsatisfied, at any rate uncertain or cautious. As he was not led to embark upon the New Science by the direct call of political problems,1 at least in the ordinary meaning of the phrase, he never descends from the contemplations of the New Science to: the practical life, even in the form which it most usually takes with a philosopher, a work or short treatise criticising laws and institutions or suggesting improvements. Even when he does dimly conceive the idea of a "practical aspect" of his science, he never supposes that so far as he is concerned it could ever exist except "within the academies." Practical philosophy "within the academies," that is to say, within the sphere of culture, is however still practical and political; and it is assuredly not the least important branch of politics. And a historian or philosopher can never entirely avoid it, though he can emphasise it more or less and develop it more or less fully. Vico does emphasise and develop it freely. The first expression of his scientific life was precisely an examination of modern methods of study and education as compared with those of the ancients: an examination which after various attempts and uncertainties in his first discoveries, took form in his University inaugural lecture of 1708, _De nostri temporis studiorum ratione._ In the following years, engaged as he was upon the New Science, he gave no further public demonstration of his discontent with the prevailing tendency of studies; but he expressed his feelings on the subject all the more often and all the more strongly in private letters, and did not wish to pass over the question in his autobiography. We need not then infer his polemical attitude from hints and chance phrases of his chief work; since he has himself more than once converted these hints into explicit statements and these chance phrases into leading propositions.
