20th Century Philosophy is characterized by diverse movements and ideas that emerged in response to modernity, science, and existential concerns. Key figures include Ludwig Wittgenstein, who explored language and meaning, and Martin Heidegger, who examined existence and being. This period also saw the rise of existentialism, emphasizing individual experience and freedom, with philosophers like Jean-Paul Sartre and Simone de Beauvoir. Additionally, analytic philosophy gained prominence, focusing on clarity and logical analysis, with contributors such as Bertrand Russell and Willard Van Orman Quine. Meanwhile, postmodernism challenged established narratives and truths, with thinkers like Michel Foucault and Jacques Derrida questioning the nature of knowledge and power.
