The idea that society may be studied in a standardized and objective manner, with scholarly rules and methodology, is comparatively recent. While there is evidence of early sociology in medieval Islam, and while philosophers such as Confucius had long since theorised on topics such as social roles, the scientific analysis of "Man" is peculiar to the intellectual break away from the Age of Enlightenment and toward the discourses of Modernity. Social sciences came forth from the moral philosophy of the time and was influenced by the Age of Revolutions, such as the Industrial revolution and the French revolution. The beginnings of the social sciences in the 18th century are reflected in the grand encyclopedia of Diderot, with articles from Rousseau and other pioneers.
