Martin Heidegger in the context of "Heraclitus"

German philosophy, meaning philosophy in the German language or philosophy by German people, in its diversity, is fundamental for both the analytic and continental traditions. It covers figures such as Gottfried Wilhelm Leibniz, Immanuel Kant, Georg Wilhelm Friedrich Hegel, Karl Marx, Friedrich Nietzsche, Martin Heidegger, Ludwig Wittgenstein, the Vienna Circle, and the Frankfurt School, who now count among the most famous and studied philosophers of all time. They are central to major philosophical movements such as rationalism, German idealism, Romanticism, dialectical materialism, existentialism, phenomenology, hermeneutics, logical positivism, and critical theory. The Danish philosopher Søren Kierkegaard is often also included in surveys of German philosophy due to his extensive engagement with German thinkers.

Praxis is the process by which a theory, lesson, or skill is enacted, embodied, realized, applied, or put into practice. "Praxis" may also refer to the act of engaging, applying, exercising, realizing, or practising ideas. This has been a recurrent topic in the field of philosophy, discussed in the writings of Plato, Aristotle, St. Augustine, Francis Bacon, Immanuel Kant, Søren Kierkegaard, Ludwig von Mises, Karl Marx, Antonio Gramsci, Martin Heidegger, Hannah Arendt, Jean-Paul Sartre, Paulo Freire, Murray Rothbard, and many others. It has meaning in the political, educational, spiritual and medical realms.

Existentialism is a family of philosophical views and inquiry that explore the human individual's struggle to lead an authentic life despite the apparent absurdity or incomprehensibility of existence. In examining meaning, purpose, and value, existentialist thought often includes concepts such as existential crises, angst, courage, and freedom.

Existentialism is associated with several 19th- and 20th-century European philosophers who shared an emphasis on the human subject, despite often profound differences in thought. Among the 19th-century figures now associated with existentialism are philosophers Søren Kierkegaard and Friedrich Nietzsche, as well as novelist Fyodor Dostoevsky, all of whom critiqued rationalism and concerned themselves with the problem of meaning. The word existentialism, however, was not coined until the mid 20th century, during which it became most associated with contemporaneous philosophers Jean-Paul Sartre, Martin Heidegger, Simone de Beauvoir, Karl Jaspers, Gabriel Marcel, Paul Tillich, and more controversially Albert Camus.

Jacques Derrida (/dɛrɪˈdɑː/; French: [ʒak dɛʁida]; born Jackie Élie Derrida; 15 July 1930 – 9 October 2004) was a French philosopher. He developed the philosophy of deconstruction, which he utilized in a number of his texts, and which was developed through close readings of the linguistics of Ferdinand de Saussure and Husserlian and Heideggerian phenomenology. He is one of the major figures associated with post-structuralism and postmodern philosophy although he distanced himself from post-structuralism and disavowed the word "postmodernity".

During his career, Derrida published over 40 books, together with hundreds of essays and public presentations. He has had a significant influence on the humanities and social sciences, including philosophy, literature, law, anthropology, historiography, applied linguistics, sociolinguistics, psychoanalysis, music, architecture, and political theory.

Luce Irigaray (born 3 May 1930) is a Belgian-born French feminist, philosopher, linguist, psycholinguist, psychoanalyst, and cultural theorist who examines the uses and misuses of language in relation to women. She is considered one of the founders of French difference feminism.

Irigaray's first and most well known book, published in 1974, was Speculum of the Other Woman (1974), which analyzes the texts of Freud, Hegel, Plato, Aristotle, Descartes, and Kant through the lens of phallocentrism. Irigaray is the author of works analyzing many thinkers, including This Sex Which Is Not One (1977), which discusses Lacan's work as well as political economy; Elemental Passions (1982) can be read as a response to Merleau‐Ponty's article “The Intertwining—The Chiasm” in The Visible and the Invisible, and in The Forgetting of Air in Martin Heidegger (1999), Irigaray critiques Heidegger's emphasis on the element of earth as the ground of life and speech and his "oblivion" or forgetting of air.

Henry Corbin (14 April 1903 – 7 October 1978) was a French philosopher, theologian, and Iranologist, professor of Islamic studies at the École pratique des hautes études. He was influential in extending the modern study of traditional Islamic philosophy from early falsafa to later and "mystical" figures such as Suhrawardi, Ibn Arabi, and Mulla Sadra Shirazi. With works such as Histoire de la philosophie islamique (1964), he challenged the common European view that philosophy in the Islamic world declined after Averroes and Avicenna.

Born into a Catholic family, he converted to Protestantism between 1927 and 1930. He received a Catholic education, obtaining a certificate in Scholastic philosophy from the Catholic Institute of Paris at age 19. Three years later he took his "license de philosophie" under the Thomist thinker Étienne Gilson. He studied modern philosophy, including hermeneutics and phenomenology, becoming the first French translator of Martin Heidegger. On 13 October 1929, Louis Massignon (director of Islamic studies at the Sorbonne) introduced him to Suhrawardi, the 12th-century Persian Muslim thinker. In a late interview, Corbin said: "through my meeting with Suhrawardi, my spiritual destiny ... was sealed. Platonism, expressed in terms of the Zoroastrian angelology of ancient Persia, illuminated the path that I was seeking." He thus dedicated himself to understanding Iranian Islam, which he believed esoterically expressed older perennial insights related to Zoroastrianism and Platonism.
