## TL;DR

Aesthetics is the philosophical study of beauty, art, and taste. Key questions: What makes something beautiful? Is beauty objective or subjective? What is art? Kant: beauty is 'purposiveness without purpose' — judged disinterestedly (without personal stake). Hume: 'Beauty is no quality in things themselves: it exists merely in the mind.'

## Core Explanation

Kant: the beautiful produces 'free play' of imagination and understanding, pleasing universally (subjective universal). Sublime: awe-inspiring (starry sky), overwhelms but from safe distance. Duchamp's Fountain (1917): urinal as art — challenged aesthetics entirely. 'Artworld' theory (Danto, 1964): Art is whatever the artworld accepts as art. Institutional theory (Dickie): art is artifact presented to artworld public. 'Beauty is truth, truth beauty' (Keats).
