The true and only reality then, in the world of nations, is the course of their history: and the principle which regulates this course is Providence. From this point of view the New Science may be defined as a "rational civil theology of the divine providence." Bacon, among his historical sciences, had named a _Historia Nemeseos_ (history of Divine Retribution). What for Bacon was little more than a mere name was for Vico a clearly stated problem and a developed theory. Philosophers, according to him, when they did not ignore Providence entirely, as materialists and determinists, considered it solely in the sphere of natural law, calling metaphysic by the name of "natural theology," and supporting the identification of God with the natural order observed in the motions of bodies, such as the spheres and the elements, and with the final cause which was seen to exist over and above the other natural causes. As against all this it was important to work out the doctrine of Providence "in the economy of matters civil." It was observed by some of his earliest commentators, and the observation has been frequently repeated since, that Vico used the word "providence" indifferently in a subjective and an objective sense: sometimes to indicate the human belief in a provident deity controlling their doctrine, sometimes to denote the actual operation of this providence. The double or triple meaning of a single word in Vico's terminology is a thing which by now need cause no astonishment. We have often already been obliged to take pains to distinguish his homonyms and unite his synonyms. Hence we may at once recognise that one meaning of "Providence" for Vico might be and indeed is the belief in Providence, man's idea of God, first in the form of myth and later in the pure and rational form of philosophy. The Gentile nations of antiquity, he says, "began their metaphysical poetic wisdom by contemplating God in the attribute of his providence," upon which rested augury and divination. Without this idea, then, wisdom, the consciousness of the infinite, cannot take shape within man, nor can morality, the fear of and respect for the higher power which governs the affairs of men, arise. But in this sense of the word a further discussion of providence is unnecessary, after what we have said on the subjects of mythology and of the relation between morality and religion. We therefore pass at once to Providence in its second sense, the real and strict conception of it; and here it seems advisable to leave Vico for a moment and to clear up certain points of doctrine.
