Ernst Cassirer (1874-1945) significantly influenced the strategic fundamental debates of philosophy in the last decades of modernity like few others. Cassirer, who expanded Neo-Kantianism with the approach of cultural science and ultimately arrived at an overarching philosophy of culture, is particularly known for his "Philosophy of Symbolic Forms." All human experience, which manifests in language, myth, religion, art, and science, is symbolically shaped. Forms of meaning mediate between the self and the world. This introduction presents the fundamental ideas and the life work of Cassirer in an understandable and reader-friendly brevity.
