In
philosophy,
temporality is traditionally the linear progression of past, present, and future. However, some modern-century philosophers have interpreted temporality in ways other than this linear manner. Examples would be
McTaggart's
The Unreality of Time,
Husserl's analysis of internal time consciousness,
Martin Heidegger's
Being and Time (1927),
George Herbert Mead's Philosophy of the Present (1932), and
Jacques Derrida's criticisms of Husserl's analysis, as well as
Nietzsche's
eternal return of the same, though this latter pertains more to
historicity, to which temporality gives rise. In social sciences, temporality is also studied with respect to human's perception of time and the social organization of time. The perception of time undergoes significant change in the three hundred years between the Middle Ages and Modernity.
