Art is a diverse cultural activity centered on creative talent, but it has no universally agreed definition, with interpretations varying greatly across history and cultures. In the Western tradition, it originally covered painting, sculpture, and architecture, but now broadly includes performing arts, literature, music, and film, with the specific sense of fine art emerging in the early 17th century to separate aesthetic pursuits from crafts or sciences. The word derives from the Latin for "skill" or "craft," and its philosophical nature has been explored by thinkers like Plato, Aristotle, and Immanuel Kant within the field of aesthetics. Aristotle considered art to be mimetic (imitative), distinguishing forms like tragedy and comedy by their medium, object, and manner, while Plato famously questioned its rationality, even proposing to ban Homer's poetry in The Republic. Existing from prehistoric art to contemporary works, art has been a constant of human history, though some theorists argue the modern concept of "artistic works" does not fit well outside modern Western societies.
