Our contemporary history is to be seen in the grip of the event. Modern sciences live to the rhythm of the event and define “crucial experience” as an event that generates verifiable consequences. In metaphysics, following M. Heidegger, we consider that historicity is part of the human to-be-in-the-world. A philosophy of the event leads us to think about the singular and the succession.The event is also what will change the route of the individual: adversity, life’s trials, turning points in the existence that stand out in a biography.Either at the level of general history or of an individual subjectivity, the event is an act of language for the subject of a history within the scope of a contingent temporality. Any event could have not been. Unless we resort to a mystical thought of the “miracle”, every event is linked to a field of causality (-ies) that can be fictional.
