 The academic context in which the discipline developed, however, has not prevented philosophers from engaging in social and political activities, and, especially, in debates concerning the history, culture and direction of the emerging nations. Philosophers have been important political figures since the early republic as well as leaders in the university reform processes that have taken place during the country’s modern history. During the period of military rule (1973–1990) several became important opponents of the regime. A concern for politics, in fact, has dominated the agenda of philosophers, including those who have denounced the encroachment of politics in the discipline.
