Modernity as a period of human history, but above all as social imaginary, has been one of the topics most widely studied by Canadian author Charles Taylor. The article explores the concept of "closed world structures" through which the author argues that modernity is located within a framework closed to transcendence, and that such a framework has been built on the philosophical thought as a result of some epistemological, ethical and anthropological positions. The contrast between that what is closed and open, the immanence and transcendence, are the key elements of understanding proposed by Taylor to form the map of modern and contemporary thought; and, thus, explains dynamics -such as secularity- and the cultural consequences of scientific and technological development.
