In the book "Art", Clive Bell presents a revolutionary theory in the history of aesthetics, as he seeks to understand what a work of art is and what distinguishes it. Bell addresses the fundamental question of whether it is possible to construct an objective theory of art, despite the subjective nature of aesthetic experience. The author presents the concept of "aesthetic emotion" and "significant form" as basic tools for evaluating works of art, and distances artistic judgment from external influences such as political, social, or cultural conditions. The book is considered a revolutionary step in the transition from a philosophy of art based on simulation to a philosophy based on creation, which opens the way for defining a "metaphysical hypothesis" as a subjective criterion for a work of art, making the experience of art independent and self-contained.
