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.

Early philosophy marks the transition from mythological explanations to rational discussion about the nature of reality. Pre-Socratic thinkers began exploring natural phenomena and the cosmos without relying on supernatural accounts. Socrates introduced the importance of self-examination and ethical inquiry, setting the stage for his students. Plato expanded these ideas through his theory of forms, proposing abstract realities behind everyday experiences. Aristotle systematized logic, ethics, and metaphysics, creating frameworks that still influence philosophical debates today.

Aristotle pioneered a systematic approach across several domains of philosophy. In logic, he developed the syllogism—a structured form of argument that outlines premises leading to conclusions—laying the groundwork for formal reasoning. In ethics, he articulated the concept of virtue as a balanced mean between extremes, emphasizing that moral virtue is achieved through habit and practical wisdom. His work in metaphysics explored the nature of being, substance, and causality, investigating what fundamentally constitutes reality. Collectively, these contributions provided a framework that deeply influenced subsequent philosophical inquiry.
