The history of philosophy traces the evolution of thought from ancient times to the present. Philosophers have questioned existence, ethics, logic, and knowledge, adapting ideas through different eras. Ancient philosophers like Plato and Aristotle laid the groundwork for metaphysical and epistemological inquiry. Medieval thinkers, influenced by religion, merged classical ideas with theological traditions. The modern period saw a shift toward individual reason and scientific inquiry during the Enlightenment, leading to diverse schools of thought. In contemporary philosophy, debates continue across ethics, language, mind, and society, building on this long, interconnected tradition.

After the Modern period, philosophy entered the Contemporary era. This phase built on earlier ideas while engaging with new issues in ethics, language, mind, and society, marking an evolution in thought that continues today.

Postmodern philosophy emerged in the latter half of the 20th century as a critical response to modern ideas. While contemporary philosophy is a broad category, postmodernism specifically challenges the notions of objective truth, universal narratives, and grand theories. It emphasizes pluralism, relativism, and skepticism towards meta-narratives, influencing debates in ethics, language, culture, and power structures.

Key figures include Jean-François Lyotard, known for his critique of metanarratives; Jacques Derrida, who pioneered deconstruction; Michel Foucault, who reexamined power and knowledge relations; and Jean Baudrillard, who explored concepts like simulacra and hyperreality. These thinkers, among others, significantly shaped postmodern thought.
