Ernst Cassirer

Ernst Alfred Cassirer was a prominent German philosopher and historian of philosophy. He was a leading figure in 20th-century philosophical idealism. This school of thought explores how human consciousness and ideas shape our reality. Cassirer spent his life investigating how humans interpret the world through various lenses. He sought to connect the logical structures of science with the creative structures of culture. His work remains significant for its attempt to understand the human spirit.

Cassirer’s intellectual development followed a specific path through several academic disciplines. He began his studies in Jurisprudence at the University of Berlin and Leipzig. He also studied Germanic Philology, Literary History, and Philosophy at Heidelberg. Later, he focused on Philosophy and Psychology at the Ludwig-Maximilians-Universität München. His doctoral training took place at the University of Marburg. There, he studied under Hermann Cohen and Paul Natorp. He also studied Mathematics with Friedrich Schottky. This diverse training allowed him to bridge the gap between science and the humanities.

One of Cassirer’s most influential theories was his concept of the "symbolic animal." In his work, *Philosophy of Symbolic Forms* (1923–1929), he argued that humans are unique. While animals rely on instinct and direct sensory perception, humans use symbols. These symbols include natural language, myth, art, and mathematics. Cassirer believed that these symbolic systems create a universe of meaning for us. He suggested that science and mathematics grew from language. Similarly, he believed religion and art grew from the foundations of myth.

Cassirer’s academic career was marked by significant roles and major shifts. In 1899, he published a dissertation on René Descartes's analysis of science. In 1906, he completed his habilitation at the University of Berlin. He worked for many years at the Friedrich Wilhelm University in Berlin. In 1919, he was elected to the philosophy chair at the University of Hamburg. He lectured there until 1933, where he supervised doctoral students like Leo Strauss. His career was interrupted by the rise of the Nazi regime. Because he was Jewish, he left Germany in March 1933.

Following his departure from Germany, Cassirer lived a nomadic academic life. He taught at the University of Oxford and the University of Gothenburg. He eventually moved to the United States to find stability. In 1941, he served as a visiting professor at Yale University. From 1943 until his death in 1945, he lectured at Columbia University in New York City. Cassirer died of a heart attack in April 1945. His funeral service at Columbia was conducted by the student Arthur Hertzberg.

Cassirer also engaged in deep debates regarding the nature of truth and reason. In 1929, he participated in the famous Cassirer–Heidegger debate in Davos. He argued against the relativism of Martin Heidegger. Cassirer believed that truths found in moral and exact sciences have universal validity. He also wrote extensively on the philosophy of science. In *Einstein's Theory of Relativity* (1921), he defended neo-Kantian views of knowledge. He also explored quantum mechanics in his 1936 book, *Determinism and Indeterminism in Modern Physics*.

In his final years, Cassirer turned his attention to the dangers of irrationality. His posthumous work, *The Myth of the State* (1946), examined the intellectual roots of Nazi Germany. He analyzed how fascist propaganda used myth to bypass rational logic. He saw this as a surrender to the "irrationality of myth." Cassirer believed that reason and the Enlightenment were tools for human liberation. He argued that a society must check the power of myth with superior rational forces. His work serves as a warning about the loss of logical thought in politics.
