The Republic of Letters was the sum of a number of Enlightenment ideals: an egalitarian realm governed by knowledge that could act across political boundaries and rival state power. It was a forum that supported "free public examination of questions regarding religion or legislation". Immanuel Kant considered written communication essential to his conception of the public sphere; once everyone was a part of the "reading public", then society could be said to be enlightened. The people who participated in the Republic of Letters, such as Diderot and Voltaire, are frequently known today as important Enlightenment figures. Indeed, the men who wrote Diderot's Encyclopedie arguably formed a microcosm of the larger "republic".
What did Immanuel Kant consider essential to his conception of the public sphere?
written communication

Although theoretically a collegial body operating through consensus building, Gaddafi dominated the RCC, although some of the others attempted to constrain what they saw as his excesses.

Control of labour and inter-group conflict is characteristic of corporate-level or 'tribal' groups, headed by a charismatic individual; whether a 'big man' or a proto-chief, functioning as a lineage-group head. Whether a non-hierarchical system of organization existed is debatable, and there is no evidence that explicitly suggests that Neolithic societies functioned under any dominating class or individual, as was the case in the chiefdoms of the European Early Bronze Age. Theories to explain the apparent implied egalitarianism of Neolithic (and Paleolithic) societies have arisen, notably the Marxist concept of primitive communism.
What type of disagreement existed in tribal groups that were controlled by charismatic leaders?
inter-group conflict
