Evaluating Martin Heidegger is complicated by his support for the National Socialists. Here was a man close to noted Jewish thinkers — yet he embraced the Nazi movement. Some evil people have a few “good” values, while some good people end up associated with serious evil.

Revising Never Ends, Nor Should It…

Do not use this site as a study guide. The Existential Primer is a “living” academic project, unlike a static text. This primer is only a shallow introduction to the thinkers profiled. The incomplete nature of this website might result in misunderstanding the profiled individuals. These pages are revised often because scholarship is never ending. Consult any citations included because within them is where you will find the experts. Read their works!

NOTE: Citations are not in MLA or APA format to prevent “borrowing” from The Existential Primer. Full lists of citations appear at the end of each page. Present tense is used when referencing a published work, while past tense is favored on these pages because the major figures are… dead. Inline citations take the form (Author p. page) with no year.

Some lives go full-circle, and Martin Heidegger’s life began and ended in the Black Forest. Born 26 September 1889 in Messkirch, he would later return to the Black Forest to escape his legacy as a Nazi sympathizer.

Martin Heidegger was a student of, and assistant to, Edmund Husserl, whom he succeeded in 1928 as professor of philosophy at Freiburg. Heidegger began his rise in the academic establishment as a phenomenologist, under the guidance of Husserl. In fact, Heidegger’s classic work, Being and Time was published in the 1927 Yearbook for Phenomenolgy and Philosophical Research.Heidegger

One of Heidegger’s students was Jean-Paul Sartre, later the most prominent French Existentialist. Sadly, history drove the two men apart, as Heidegger remained in Germany under the National Socialists, even joining the Nazi Party.

Many students of philosophy have difficulty separating Heidegger’s brilliance and use of curiously-mystic language from his support of Adolph Hitler and the National Socialists from 1933 through 1945. It must be understood that Heidegger, like all philosophers, was not immune to the events around him. This observation is a contradiction of the idea that all men are responsible for their actions, regardless of outside influences.

Heidegger, who in Sein und Zeit had spoken much of resolutely facing death, joined the Nazis after Hitler came to power and, as Rektor of his university, delivered an inaugural address which, fortunately for him, is not widely read. If, as he now says, he soon abandoned Nazism, it is the more remarkable that his resolve was kept so quiet that even today many remain unconvinced.
- Existentialism; Kaufmann, p. 47

Professor Richard Wolin and other researches now believe Heidegger was dedicated to the National Socialist Party, indifferent to how Hitler ruled Germany.

Though [Richard] Wolin’s grievance with Derrida is not at issue in “Heidegger’s Children,” one can’t help feeling that, indirectly, it is being reprised. The heart of the controversy was Wolin’s accusation that Derrida had tailored his “far-fetched and illogical” opinions about Heidegger’s Nazism to dodge an important question: by embracing the legendary German thinker’s philosophy, had Derrida and other radical postmodern leftists accepted the core of Heidegger’s dubious politics as well?

The Germany in which Heidegger lived was a country in a constant state of war and division. Only a few years before his birth, modern Germany was formed out of formerly feuding regions. Germany is a country with few natural borders, leading its leaders to believe that the best way to maintain Germany was a strong military. These military forces often collided.

Heidegger came to desire a state ruled by an elite group of soldier-philosophers. He came to distrust the public tastes, modernity, and democratic institutions. The National Socialists matched his vision of a new, powerful central government. What one must wonder is how Heidegger reconciled his relationships with students of Jewish descent with the Nazi concentration camps.

Before Heidegger became the Nazi rector of the University of Freidburg in 1933, he served as teacher and sage to four gifted students of assimilated German Jewish backgrounds. Hannah Arendt, who at 18 began a three-year love affair with Heidegger, achieved fame as a political thinker. Herbeert Marcuse, denounced by the Pope in the late 1960s, became a philosophical guru for the New Left. Hans Jonas matured into a pioneering theorist of environmentalism, serving as a touchstone for the German Green Party. And Karl Lowith became a distinguished scholar of modern historical consciousness.

One reason that Heidegger may not have opposed the Nazi conquests of World War II was the long-standing German distrust of the French. Napoleon I had conquered Germany. As a result, many Germans still consider the French culture a threat the German heritage. Later in life, many Germans would view the Soviet Union in the same light. Until his death, Germany was still an important site of the Cold War between Communism and Western democracies.

Heidegger is known to have referred to the “inner truth and greatness” of the Nazis long after the fall of the Third Reich. German superiority and nationalistic pride obscured Heidegger’s views of history.

What makes Heidegger curious as a founder of existentialism is that he strongly objected to being considered one of The Existentialists, which would place him in company with Sartre and Camus. These men, French communists, were not the sort that Heidegger wanted anyone to link to him.

Martin Heidegger began as a recognized authority in the phenomenological movement and became an existentialist with theistic leanings. Heidegger based his philosophy upon the “hermeneutics of existence” — or the science of existence. The “scientific” method was that of phenomenological reduction.

Kierkegaard accepted the paradox of being defining itself. As a scientist, Heidegger could not accept this paradox. According to Heidegger, a concept must be defined without using itself as reference. The difficulty of definition was confronted by defining “Being” as a collection of concepts.


According to Heidegger's writings, human being -- as opposed to human beings -- is comprised of four components: concern, being-toward-death, existence, and moods. Dasein is the act of "being there" in essence. Without being something, there is no existence.

Concern, or Sorge, is the ability to care about the self, in relation to phenomena. Being-toward-death, or Sein zum Tode, represents the finite nature of life. This belief that death defines life complements Søren Kierkegaard's thought that God does not exist, but is real. Existence, or Existenz, represents knowing one is and is changing. Finally, moods, or Stimmungen, are reactions to other beings, further allowing one to define the self.

Dasein requires choices and resulting actions to define the self. These choices allow for an almost unlimited combination of the components of being. Each choice represents a pivotal point in the individuals life -- every choice, even the seemingly minor ones, contribute to the larger definition of self. Choices occur in relation to a timeline, universal and personal. These points in time became the topic of Heidegger's Being and Time.

Existence and Essence

As with Kierkegaard and Sartre, Heidegger believed the existence of a physical body preceded the essence of self. At some point in the development process, a being becomes aware that it exists. This pivotal point in time is when essence begins to form; the individual decides to acknowledge and embrace an essence at this moment.

Because man in the only known being in which essence and existence do not appear simultaneously, man is a unique creature on this planet. All things man creates have essence, or definition, before they exist. In other words, an individual thinks about a creation and its purpose before the creation exists.

Dasien Sorge

Dasien Sorge was Heidegger's term for concern and caring about the self and its existence. When confronted with the world and other beings, the individual feels anxiety and dread. The world appears complex and unsafe -- which it is. As a result, the human being, Dasien, must care for itself as no one else can or will.

Taking care of the self is a sign that the individual recognizes dangers in the universe. Recognizing threats demonstrates an understanding of the physical self. It is reasonable to conclude that concern with the physical self precedes the awareness of concern for the emotional self. While a child might instinctively want human contact, it only understands the need for food and other basic physical needs.

Classes of Dasein Existence

Being-there, Dasein, can be expressed in several fashions. The five modes of Dasein described by Heidegger are: authenticity, inauthenticity, everydayness, averageness, and publicness. Authentic being represents a choice of self and achievement. All other modes represent a failing to embrace the individuality available to all people.

Inauthenticity results from business, preoccupation, excitement, and other external forces. An inauthentic being is working to fit the definitions of others. Averageness takes hold when the individual no longer attempts to achieve and accepts a loss of differentiation. Everydayness represents a person no longer changing or making choices, but the individual might still be different from others. Many with achievement become everyday when they no longer attempt to excel.

Publicness is the complete loss of self for a public image. The individual conforms to preconceptions and opinions. Unlike the celebrity with one achievement, this individual repeats the same achievement over and over, thereby withdrawing from independence. An example would be an artist with one style of expression, repeated with minor variations to please others. By avoiding the new, the different, the individual ceases to create and define a self.

Sein zum Tode: Toward Death

The only proof that an individual understands existence is the understanding and acceptance of death. While a child can understand the physical need for food, the known consequences of not eating are limited to hunger and illness. Death is a complex concept, beyond the grasp of an immature existence.

The moment one accepts death is the point when essence is brought into focus. Knowing that life is finite reinforces the importance of all further decisions. Poor choices result in the "Existential Guilt" of failure. For the existentialist, the worst of natural sins is a failure to define the self using free will. Guilt cannot be avoided, however, because all individuals fail to take some action, to make some choices.

Desire to Be

Though life is filled with dread that the universe is not safe and guilt that life is every complete, the human being has a desire to exist and define the self. The pursuit of authenticity is constant, for the existentialist. While it cannot be perfected, as we coexist with other beings, individuals must work to define themselves.

Individuals make decisions knowing that others might try to change the universe around them. Business is unavoidable, as is a public role in the society. Only the most dedicated existential being can rise above these challenges to define the self, without regard to others.
