Martin Heidegger was born in 1889 in the southwest side of Germany. When he was a child, he was prepared to become a priest but that changed when he went to high school. He first got interested in philosophy when he read Franz Brentano’s book called “On the Manifold Meaning of Being according to Aristotle”. With that it started his long life quest of finding the meaning of being. In 1923, Heidegger was appointed associate professor at Marburg University. There is where his teaching career blossomed. His students testified to the originality of his insight and the intensity of his philosophical questioning. Soon after he expanded his lectures and taught history of philosophy, time, logic, phenomenology, Plato, Aristotle, Aquinas, Kant, and Leibniz. Heidegger most famous book that influence many people was “Being and Time”.
The book “Being and Time” talks about every thing what Heidegger belive metaphysic is. Metaphysics thinks about beings as beings. As a root of a tree, it sends all the nourishment and strength into the trunk and it’s branches. The root branches out in the soil to let the tree grow out of the ground and thus to leave it. The tree of philosophy grows out of the soil which metaphysics is rooted. Metaphysics speaks continually and in the most various way of Being. It operates was a prior conception of Being. Metaphysics doesn’t induce Being itself to speak, doesn’t recall Being in its truth, nor does it recall truth as unconcealedness, and doesn’t recall the nature of unconcealedness. To metaphysics the nature of truth always appears in derivative form of the truth of knowledge and the truth of proposition which forms our knowledge. Metaphysics thinks of Being by only representing beings as beings. Meaning that all beings as a whole, although it speaks of Being. It refers Being and means beings as beings. In the language of metaphysics the word “existence” is a synonym of “being there”. They both refer to the reality of anything that is real, from God to a grain of sand. The word “existence” is used solely for the being of man. Once it is understood rightly, the essence of being there can be recalled. Being itself manifests and conceals itself, yield itself, and withdraws. The truth of Being does not exhaust itself in being there, nor can it by any means be identified with it after the metaphysical proposition that all objectivity is as such also subjectivity.
To me if I had to read the book I think I would just want to blow my brains out. “Beings as beings” kind of confusing and the book will probably mention it like a hundred times. That’s really all I can say other than Heidegger lived a good life and even though he was involved in both World Wars, he still kept believing in his philosophy.
