Martin Heidegger was a famous German philosopher who was known for his work in existentialism and phenomenology. Heidegger was born in 1889 and died in 1976. Heidegger is considered one of the most important philosophers of the 20th century, and he influenced many other philosophers such as Jean-Paul Sartre, Jacques Derrida and Michel Foucault.
Heidegger’s most significant contribution to philosophy is his focus on human existence as being thrown into an existing world without choice or control. He argued that people experience the world through their own unique perspective which is shaped by their individual past experiences and cultural position. This concept became known as “being-in-the-world” or “being there” (Dasein). Dasein does not have free will because it exists within a set of social structures that determine what it can do and how it thinks about things. For example, people often think about certain things because they conform to certain standards set by society or culture at large, rather than because there is any real reason for them to believe this way or another – they just do it because everybody else does it too.
Philosopher’s thought has often been characterized as being dark and terrifying. His most famous work is Being and Time (1927), which he wrote during his time teaching at Freiburg University.
