Aestheticism, a modernist literary trend popular in Europe at the end of 19. Gauthie, a French romantic poet, put forward the slogan of "Art for Art's sake", claiming that art itself is an end, flaunting that literature and art are divorced from society, advocating pure aestheticism and pursuing abstract artistic effects. This view was fully reflected in the creation of Wilde and others, and was later systematized by British literary theorist Pater. The rise of aestheticism is a resistance to utilitarian philosophy, philistinism and vulgar style in capitalist society, and its ideological basis can be traced back to Kant's aesthetic thought. It pursues the formal beauty and expressive skills of art and creates various fields of artistic beauty such as grotesque, ugly, decadent and surly, thus expanding the scope and ability of artistic expression, and is an important part of decadent literature and art.
