Phenomenology is the study of structures of conscious experience. It asks not what exists, but what it is like to experience what exists. Edmund Husserl founded the movement in the early 20th century, arguing that philosophy should return to the things themselves, to the lived world of experience. He developed the method of epoché, or bracketing, in which the phenomenologist suspends judgment about whether the world exists in order to describe how it appears. Martin Heidegger, Husserl's student, shifted the focus to being-in-the-world, arguing that we are always already engaged with the world, not detached observers. Maurice Merleau-Ponty emphasized the body as the medium of experience. Jean-Paul Sartre applied phenomenology to freedom, imagination, and emotion.

Phenomenology has influenced psychology, psychiatry, sociology, architecture, and cognitive science. It is not a single doctrine but a method and a tradition. It insists that experience is not just data to be explained but a dimension of reality to be described. Its central insight is that consciousness is always consciousness of something. It is intentional. It is directed toward objects, and those objects are given in specific ways. Phenomenology studies those ways.

Key phenomenologists

• Husserl. Founder, developed the method of bracketing.
• Heidegger. Being-in-the-world, authenticity, anxiety.
• Merleau-Ponty. The lived body, perception, ambiguity.
• Sartre. Freedom, imagination, bad faith.

Phenomenology is not introspection. It is a rigorous description of the structures of experience, not a report of personal feelings.
