Contributions to Philosophy (Of the Event) (German: Beiträge zur Philosophie (Vom Ereignis)) is a work by German philosopher Martin Heidegger. Composed privately between 1936 and 1938, but not available to the public until it was published in Germany in 1989, the work is thought to reflect "the turn" (die Kehre) in Heidegger's thought after Being and Time (1927). It may be considered Heidegger’s second major work. However, it has been noted that there is far less consensus about this book than nearly any other piece of 20th-century philosophy.
