Vico's position here and in later works is not that the Cartesian method is irrelevant, but that its application cannot be extended to the civic sphere. Instead of confining reason to a string of verifiable axioms, Vico suggests (along with the ancients) that appeals to "phronēsis" (φρόνησις or practical wisdom) must also be made, and likewise appeals to the various components of persuasion that comprise rhetoric. Vico would reproduce this argument consistently throughout his works, and would use it as a central of the "Scienza Nuova".
