Kant and Heıdegger on Phenomenon: a Crıtıcal Comparıson

The phenomenon is one of the ancient words in the history of western philosophy. It is used repeatedly in the works of Plato and Aristotle, and also is in Hume, Kant, Hegel, Husserl, Heidegger, and many other philosophers. In this essay, the main topic is comparing the sense of phenomenon in Kant and Heidegger. This is important because Kant's thoughts have caused fundamental changes in philosophy and as he claims he has created a Copernican Revolution in philosophy. It seems that his consideration of Phenomenon is, at least, one of the main elements of his Copernican Revolution, and, since he is one of the greatest modern philosophers, his understanding of the meaning of phenomenon has an essential relation to modern thought. The questions of this essay are: 1. what does phenomenon mean to Kant? And which consequences does it bring about? 2. What does phenomenon mean to Heidegger and how does he reject Kantian Phenomenon?
