The Social Contract by Jean-Jacques Rousseau

As long as several men in assembly regard themselves as a single body, they have only a single will which is concerned with their common preservation and general well-being. In this case, all the springs of the State are vigorous and simple and its rules clear and luminous; there are no embroilments or conflicts of interests; the common good is everywhere clearly apparent, and only good sense is needed to perceive it. Peace, unity and equality are the enemies of political subtleties. Men who are upright and simple are difficult to deceive because of their simplicity; lures and ingenious pretexts fail to impose upon them, and they are not even subtle enough to be dupes. When, among the happiest people in the world, bands of peasants are seen regulating affairs of State under an oak, and always acting wisely, can we help scorning the ingenious methods of other nations, which make themselves illustrious and wretched with so much art and mystery?

A State so governed needs very few laws; and, as it becomes necessary to issue new ones, the necessity is universally seen. The first man to propose them merely says what all have already felt, and there is no question of factions or intrigues or eloquence in order to secure the passage into law of what everyone has already decided to do, as soon as he is sure that the rest will act with him.
