temporality

Temporality refers to the existence and experience of time—the ordering, duration, and flow of events. It is a central concept in philosophy, physics, cognitive science, and the humanities, shaping how individuals remember the past, anticipate the future, and organize daily life. Different disciplines study temporality from complementary angles, ranging from the structure of time in nature to subjective time perception and calendrical systems.

Philosophical discussions distinguish between temporal structure and temporal ontology. Classic debates include the distinction between A-series time, which attributes past, present, and future to events, and B-series time, which orders events by relations such as earlier than or later than. The presentist view holds that only the present is real, while eternalism asserts that past, present, and future are equally real. Other positions include the growing block theory, where the past and present exist, but the future does not.

In physics, time is a dimension that combines with space in the spacetime of relativity. Einstein's theories show that time is relative to an observer's motion and gravitational field, leading to phenomena such as time dilation and the non-absolute simultaneity of events. The direction of time is often linked to thermodynamic entropy, producing an arrow of time from past to future.

Psychological temporality studies how humans experience durations, pace of events, and temporal attention. Time perception can vary with attention, emotion, and context, and is influenced by cultural practices such as scheduling, calendars, and time zones.

Temporality thus connects physical, cognitive, and social dimensions of time, providing a framework for understanding change, memory, causality, and the organization of human life across different scales.
