The Problem in the Ancient World. Law universal and supreme over mankind (Sophocles, Antigone). Law arbitrary and varying from place to place (Herodotus). Nature and convention. The 'rightlessness' of the stranger in antiquity. The law was a 'law of citizens'. Admission of the foreigner to legal protection. Rome develops a law of the men of all nations (_ius gentium_), which reacts upon the law of citizens (_ius civile_), and ultimately coalesces with it. The law of nature. The break-up of the Ancient World; the Middle Ages. The invaders bring their own law with them. In the kingdoms which they founded each man had his 'personal law'. Local Law. Feudal Law. The beginnings of National Law: England, France, Germany. Roman Law in the Middle Ages. The Canon Law. The Modern World. The reception of Roman Law. State Sovereignty. The Modern Codes. Unity and diversity of law within the political unit. The world divided into territories of the English Common Law and lands where Roman Law conceptions prevail. Forces making for unity: the notion of a 'law of nature'; the pursuit of common ends. International law, private and public. CHAPTER VI. THE COMMON ELEMENTS IN EUROPEAN LITERATURE AND ART The question of the place of nationality in art and literature. It has little or no place in the Middle Ages. The mediaeval epic; its character. The mediaeval romance. Modern European art and literature transcends national conditions. The characteristics of the new European literature of the fourteenth century: Dante, Boccaccio, Chaucer. The drama of England and Spain in the sixteenth and seventeenth centuries. Painting and sculpture from the fourteenth to the seventeenth century. The classical mind, and the principle of good taste and common sense. The realism of Defoe and Hogarth, and the Spanish Picaresque novel. Sentimentalism in the eighteenth century. The poetry and painting of nature. The great revolution and the romantic movement. Great literature and art are not national but human. CHAPTER VII. SCIENCE AND PHILOSOPHY Western civilization possesses a certain unity (1) in the sense of unity of character, (2) in the fact that it has a common origin, ultimately in the Greco-Roman civilization but more immediately in mediaeval Christendom, and (3) in the sense that its parts have maintained a constant intercommunication of ideas. (4) The different qualities of German, French, and English thinkers have in large measure complemented one another, (5) and the history of science and of speculative philosophy is largely a history of the interaction of distinct national schools. (6) The same thing is true of political thought. (7) Thus the world of thought forms a commonwealth which is superior to all national differences and, in spite of the war, remains a foundation of a very genuine unity. CHAPTER VIII.
