Modern western aesthetics, contrary to the traditional philosophical methods of the past, moves towards psychological aesthetics and scientific aesthetics. Psychological aesthetics uses scientific methods to study human aesthetic psychology, focusing on the subject; scientific aesthetics uses scientific methods to analyze the structure and function of aesthetic objects, focusing on the object. But no matter which method is adopted, they think that the endless philosophical speculative discussion on the nature of beauty (the definition of beauty) is of little significance. This shows that. ['Modern western aesthetics believes that philosophical thinking of traditional aesthetics is meaningless and scientific.', 'Psychological aesthetics studies human aesthetic psychology, focusing on the study of the subject and content of aesthetic objects.', 'Scientific aesthetics focuses on the study of aesthetic objects, that is, the scientific analysis of the structure and function of aesthetic objects.', 'The philosophical discussion on the essence of beauty should be abandoned.']
