The Idea of the Work
The New Science is a philosophical inquiry into the common nature of nations. Vico presents it as a “new science” because it seeks rational principles underlying the histories, customs, languages, laws, and institutions of all peoples, rather than merely narrating events. The work opens with an “Idea of the Work” that sets out its ambitious scope: to unite philosophy, which seeks the true, with philology, which studies the certain facts of languages, customs, and history. Vico argues that neither discipline is sufficient alone. Philosophy without philology becomes abstract and ignores the concrete development of humanity; philology without philosophy becomes mere erudition and cannot discern the order beneath historical particulars.
The governing principle of the work is that the true and the made are convertible. Human beings can have genuine knowledge of the civil world because they have made it, whereas the natural world is fully knowable only to God, its maker. History is therefore not an opaque succession of contingencies but a human construction whose principles can be recovered. Vico also insists that human history is governed by Providence—not a miraculous interruption of natural causes, but an immanent order through which human passions, often selfish and violent, are directed toward the formation of social institutions. The book’s aim is thus a “rational civil theology” of divine Providence: a philosophical account of how nations arise, develop, and recur according to a shared pattern.
Book One: On the Establishment of Principles
Book One lays the foundations of the science. Vico proceeds through a series of axioms, definitions, and “elements” designed to establish the principles from which the history of nations can be understood. He criticizes modern natural-law theorists and social-contract philosophers for imagining the first humans as rational individuals who deliberately chose to form society. Such accounts, he argues, project the refined reason of civilized adults back onto a primitive condition. The earliest humans were not philosophers; they were governed by imagination, fear, and bodily needs.
Vico’s alternative begins with a reconstruction of the earliest human condition. After the dispersion of peoples, the first gentiles lived solitary, bestial, and mute lives. They were “giants” in the sense of rude, untamed beings, without settled society or articulate language. The fear aroused by lightning and other natural phenomena led them to imagine a superior power—Jove—and this fear became the origin of religion. Shame, marriage, and burial followed as the first foundations of human society. Vico treats religion, marriage, and burial as the three universal institutions or customs through which nations are founded. These are not arbitrary conventions but the basic ways in which human beings emerge from bestiality into civil life.
Book One also establishes the centrality of “common sense” (senso comune). Common sense is the shared judgment of a people, prior to reflective reasoning, that gives coherence to social life. It is the basis of the “common nature of nations” that the new science seeks to understand. Vico further distinguishes sacred history, the history of the Hebrews as preserved by revelation, from the history of the gentiles, which developed through the ordinary operations of Providence. This distinction allows him to treat biblical chronology and gentile history without simply collapsing one into the other.
The principles established here include the idea of an “ideal eternal history”: a pattern that all nations follow in their development. Vico identifies three ages—the age of gods, the age of heroes, and the age of men—and corresponding forms of nature, custom, language, law, and government. These distinctions are not yet fully worked out in Book One, but they are announced as the framework for the rest of the work.
Book Two: On Poetic Wisdom
Book Two, the longest and most original part of The New Science, develops the doctrine of “poetic wisdom.” Vico argues that the first humans were not primitive philosophers but “theological poets.” Their wisdom was expressed in myths, fables, symbols, and images rather than abstract concepts. Poetry, in this sense, is not a later literary ornament but the original language of humanity. The gods of the gentiles were created by the poetic imagination as projections of fear, need, and wonder. Myth is therefore a form of knowledge, not mere falsehood.
Vico explores poetic wisdom across a wide range of domains. He treats poetic metaphysics, poetic logic, poetic morals, poetic economy, poetic politics, poetic physics, poetic cosmography, poetic astronomy, poetic chronology, and poetic geography. In each case, the argument is that early human beings understood the world through imaginative universals rather than rational categories. Poetic logic works through metaphor, simile, and fable; the first “characters” were not allegorical inventions but imaginative generalizations. Achilles, for example, is not merely an individual hero but a poetic character representing the courage of the heroic age.
This section also describes the development of language. Vico distinguishes three kinds of language: divine language, expressed in mute religious ceremonies and hieroglyphic signs; heroic language, expressed in symbols, heraldry, and poetic figures; and vulgar language, the ordinary speech of later peoples. Corresponding to these are different forms of writing and different modes of understanding. The first nations were founded by theological poets who gave names to things, instituted ceremonies, and established the first families and cities.
Poetic economy concerns the formation of the household: the father, marriage, filial piety, and the domestication of the first giants. Poetic politics concerns the emergence of cities and the conflict between the first fathers and the plebeians who sought protection and rights. Vico’s account of early society is not idyllic; it is marked by dependence, fear, and struggle. The first heroic governments were aristocratic and patrician, with the fathers holding authority over clients and plebeians.
Book Three: On the Discovery of the True Homer
Book Three applies the doctrine of poetic wisdom to the Homeric poems. Vico’s “discovery” is that Homer, as traditionally imagined—a single, wise, reflective poet—cannot have composed the Iliad and the Odyssey. The poems reflect the customs, beliefs, and language of the heroic age, not the refined philosophy of a later individual. Their inconsistencies, their mixture of customs, and their dependence on oral transmission point to a collective authorship. Homer is thus a “universal character”: the Greek people themselves, or the heroic age of Greece, speaking through the poems.
This does not mean that the poems are worthless as history. On the contrary, Vico argues that they are a great treasury of the customs of early Greece. The Iliad and the Odyssey preserve the mentality of the heroic age: its gods, its warriors, its hospitality, its piracy, its funerals, and its forms of speech. The “true Homer” is found not as a particular man but as the poetic voice of a whole epoch. This section is a test case for Vico’s broader claim that myths and poems contain the history of nations in imaginative form.
Book Four: On the Course That the Nations Make
Book Four presents the “course” that nations run according to the ideal eternal history. Vico sets out the three ages in detail. The age of gods is characterized by divine government, theocratic law, and a language of sacred ceremonies. The age of heroes is characterized by aristocratic government, heroic law, and a language of symbols and heraldry. The age of men is characterized by human government, whether democratic or monarchic, and by ordinary language and rational law.
Vico correlates these ages with three natures: the poetic or divine nature, the heroic nature, and the human nature. He correlates them with three kinds of customs, three kinds of government, three kinds of law, three kinds of judgment, and three kinds of authority. The movement is from the family to the city, from theocracy to aristocracy to democracy and monarchy. Nations develop through internal conflicts—especially the struggle between patricians and plebeians—and through the gradual extension of rights and legal equality.
The course is not a simple progress toward perfection. Vico describes how nations can decline into corruption and “barbarism of reflection,” a condition in which people use reason cynically to pursue private advantage and destroy the social bonds that earlier ages held together. When a nation becomes fully corrupt, it may be conquered or may fall back into a new primitive condition, from which a new cycle begins. This is the transition to the “recurrence” treated in Book Five.
Book Five: On the Recurrence of Human Things During the Resurgence That the Nations Make
Book Five develops the idea of ricorso, the recurrence of human things. After nations pass through their course and fall into decadence, Providence does not abandon them. A new cycle begins, but not as an exact repetition of the past. The same ideal eternal history recurs under new conditions. Vico sees in the fall of Rome and the medieval resurgence of Europe an example of this recurrence: the return of feudal lordship, violent customs, and religious authority resembles the earlier heroic age. The “barbarism of reflection” that accompanies advanced civilization gives way to a new “barbarism of sense,” and society is rebuilt from primitive foundations.
This final book reaffirms the role of Providence. The recurrence of nations is not blind fate but the work of an order that uses human freedom, passion, and conflict to preserve the human race. Vico closes the work by reflecting on the eternal natural law that nations themselves make in their historical development. The new science thus ends with a vision of history as a rational whole: a civil world made by human beings, knowable through the principles of their common nature, and ordered by a Providence that works through the very passions and conflicts that seem to divide them.
At the level of method, the New Science joins philosophy with philology. Philosophy provides the universal principles of human nature; philology provides the certain evidence of languages, customs, laws, and monuments. The resulting “mental dictionary” is meant to show how different nations express the same basic human needs under different names and images. This method corrects the “conceit of nations,” which judges every people by its own antiquity, and the “conceit of scholars,” which judges early humanity by modern rational standards and so misunderstands poetry, myth, and ritual.
The book also treats the earliest institutions—religion, marriage, and burial—as the foundations through which peoples become nations. Its notion of common sense is social rather than abstract: it is the shared, unreflective judgment that precedes philosophical reflection and makes a community possible. By recovering this common sense from language, law, and custom, the work presents history as knowable from the inside, as the product of human minds, while refusing to make modern rationality the measure of all ages.
Its significance is therefore methodological and civil at once. It offers a science of the common nature of nations that is neither a mere chronicle nor an abstract system, and it shows how reason, imagination, and custom belong to a single historical development. The New Science thus makes the human world intelligible as a world humans have made—without denying that it exceeds any single maker’s intention.
