1, look at the light and color in the sky, look at the movement of flowers and plants, look at clouds and water waves. Which artist can fully express it? Therefore, nature is always the source of all beauty and the model of all art. The ultimate goal of art is nothing more than erasing the impermanent "impression of natural beauty" from this instantaneous change, and detaining it through the role of picture carving, thus making it universal and permanent.

Art expresses "movement", but photos cannot express "movement". Movement is the truth of nature, so Rodin said, "Photos are lies, and art is real".

We compare a photo with a famous painting. Although we think the scenery in the photo is vivid, it is not vivid. Unlike the natural scenery we saw directly at that time, it has vitality and activity. If we look at the scenery in the famous paintings again, although we can't fully show the phosgene clouds in nature, we can already feel the landscapes and lifelike figures, as if we had entered the real scene.

2. When we compare the walking person in a photo with the walking person carved by Rodin, we feel that the person in the photo has raised one foot, but it seems to be numb, while Rodin's stone carving is really walking there, as if it is going far.

Rodin's sculptures like to show people's various emotional actions, because emotional actions are the most direct expression of human nature. Rodin's sculptures include ugly Mo Mu, miserable life, laughter, crying, a supreme pure ideal, and animal desire rooted in human nature. What he sees is beauty.

Rodin's The Thinker, Balzac's Literature Lane at Night, and Kissing.
