WORKS OF VICO Vico's earliest extant work is the poem entitled _Feelings of one in despair,_ composed certainly before the author's twenty-fifth year at Vatolla in the Cilento, where he lived for nine years as a tutor at the Casa Rocca, printed by Gonzatti at Venice and dated 1693. This was followed by verses and speeches of a merely rhetorical character. The philosophical characteristics are accentuated in the six speeches read by Vico at Naples University, 1699-1707, not printed by him, and rediscovered and published by Galasso (Naples, Morano, 1869). In these speeches, though some tendencies of his thought show themselves, his philosophy is still the traditional system, not without some traces of Cartesianism. Vico's opposition to Cartesianism and formal adoption of his own views are announced for the first time in the inaugural lecture for the year 1708, entitled _De nostri temporis studiorum ratione,_ published next year by the author himself (Naples, Mosca, 1709). A long digression (§§ 12-15) contains a sketch of the history of Roman jurisprudence, his first essay in the historical studies which led later on to the _Diritto universale_ and the two _Scienze Nuove._
