Oscar Wilde proposes that "Art for Art's sake" in his preface, where the aim of art is to reveal itself and conceal the artist. He defines the artist as free of ethical constraints and sees art as having no inherent moral or amoral quality. Wilde criticizes the notion that art should serve some teaching function, and argues that critics' disagreements show a work is complex and vital rather than a flaw. He sees beauty in finding meaning in beautiful things and making useless things one admires intensely.
