 Contemporary Latin American philosophy begins in the twentieth century, around 1910, coinciding with the decline of positivism. By 1930, the remaining positivists in Latin America were usually regarded as museum pieces rather than proponents of a viable philosophy meriting serious attention. The contemporary, post-positivist period can be divided into three distinct sub-periods. The first—rebellion—is characterized by the backlash against positivism and the subsequent development of foundations for future philosophical movements (ca.1910–1940). The second—normalcy—is characterized by the achievement of a degree of institutionalization and normalization in the philosophical profession (1940–1960). The third period—maturity (ca. 1960 to the present)—is distinguished by the degree of professional and philosophical maturity attained by Latin American philosophers.
