The comprehensive practice of basic education is very simple, and it comes as soon as you start writing. Theory needs to remember many complicated contents with your brain. For example, there are three main sources of western art theory.

1. Philosophers and aestheticians discuss art, involving the aesthetic tendency of the times, cultural motives, styles and schools, and so on.

2, the discussion of the artist The discussion of the artist directly starts from the personal creation, and the words are directly practical. On the other hand, the artist's narrative often contains personal emotional factors and exclusion factors, and the uncertainty of the artist's way of thinking makes it difficult to solve the problem. In addition, the study of technique treatment by artists of past dynasties is also a content.

3. The research of art historians on the phenomenon of art history is divided into two aspects: pure art history research and art phenomenon research based on certain disciplines such as philosophy and psychology. The former is becoming more and more specialized in modern times. The latter has many contents, such as Freud's research on painting based on psychoanalysis and Susan Langer's research on emotion based on psychology.
