Taking TV art as an example, National Geographic Channel enables people to learn a lot of scientific and cultural knowledge unconsciously while enjoying the beautiful pictures of TV. For natural phenomena as big as celestial bodies and as small as cells, art also has aesthetic cognitive function.

The aesthetic cognitive function of art mainly means that people can have a deeper understanding of nature, society, history and life through art appreciation activities.

Art can often profoundly reveal the true meaning and connotation of society, history and life, better reflect the depth and breadth of social life, and often bring unforgettable knowledge of social life to people through vivid and touching artistic images. For example, Engels talked about Balzac's social novel Human Comedy.

Is there a standard for judging works of art?

If we want to be serious, the standard of judgment is not the art itself, but the people.

If you don't need to be so serious, art can have standards or no standards. It develops with the changes of the times and people's needs.

I often comment on a word, a calligraphy work, especially the works of contemporary people, and sometimes I also comment on a calligraphy art. Of course, this is called calligraphy art to distinguish it from previous calligraphy works.

Everyone's aesthetic standards are different, and everyone has their own beauty in their hearts.
