Martin Heidegger was born on September 26, 1889 in Messkirch, Germany . In 1903 he went to secondary school in Konstanz and then, in 1906, he moved to Freiburg . His interest in philosophy was born during his studies in Freiburg when, at the age of seventeen, he read Franz Brentano’s book On the Multiple Meaning of Being According to Aristotle .


In 1909, he became a Jesuit novice and then entered the University of Freiburg , where he studied theology but left the seminary in 1911 and did not continue his training for the priesthood. He studied philosophy , mathematics, and natural sciences . It was also at this time that Edmund Husserl first influenced him. He studied the Logical Investigations of Husserl and in 1913 he obtained a Ph.D. in philosophy with a dissertation on The Doctrine of Judgment in Psychologism under the direction of the neo-Kantian philosopher Heinrich Rickert .

Thought of Martin Heidegger

His thinking is based on the philosophy that fully determined the meaning of being , making man an entity full of privileges who should be asked about being, since he maintains a specific relationship with it. He opposed the modern philosophy that explained how people had to face a foreign world , because for him, the human being is defined by the relationship he maintains with the world that is more practical than theoretical.

Martin Heidegger focused on studying metaphysics and made great contributions in this regard because he would address the study of the entire history of this matter.
