The Sacred and The Profane: The Nature of Religion by Mircea Eliade
In the "Sacred and the Profane", Mircea Eliade describes two fundamentally different modes of experience: the traditional and the modern. Traditional man or "homo religious" is open to experiencing the world as sacred. Modern man however, is closed to these kinds of experiences. For him the world is experienced only as profane. It is the burden of the book to show in what these fundamentally opposed experiences consist. Traditional man often expresses this opposition as real vs. unreal or pseudoreal and he seeks as much as possible to live his life within the sacred, to saturate himself in reality.According to Eliade the sacred becomes known to man because it manifests itself as different from the profane world. This manifestation of the sacred Eliade calls "hierophany". For Eliade this is a fundamental concept in the study of the sacred and his book returns to it again and again.
