On Henry Bergson’s reflection on laughter, It specifies that there are three unavoidable conditions for understanding it. The first is that it is a human gaze, because nothing is funny, in nature, nothing invites us to a discreet smile or an exaggerated outburst. We are the humans who we bring a humorous vision to neutral reality, essential characteristic of our species. The third condition of the philosopher is a consequence of the first and establishes that laughter is always group: it implies a complicity with other people who laugh. That is, the concept of humor depends on the societies. The joke is interpreted based on time and history.
