WHAT IS BEAUTY might not be a real question that demands an answer because everyone can have the experience feeling of the aesthetic sense e of beauty everyone can have the experience feeling of the aesthetic sense of beauty; though not everyone has to know the definition of Beauty. What we want to ask is: What kind of effects or inferences can the experience felling of the aesthetic sense of beauty acts upon man's life? It can be affirmed that beautiful things must be the effects of the experience felling of the aesthetic sense; and they should fill man's life full. Otherwise, there will be contradictions brought out. Beauty is a kind of abundance; and Ugliness is a kind of deficiency. Had the abundance of Beauty brings out the deficiency of Ugliness, wouldn't it be contraction? Hence, Beauty is a kind of care for man's life. The experience felling of aesthetic sense of beauty cannot be considered uncertain, otherwise it probably is just a passion for the moment that which passed only left depression. Wouldn't that result in dropping a flaw of life? To care is exactly to be abundant for each other, and the core of care is Love, in which all whatever we see or fell is beauty. Therefore, Love and Beauty are precisely to become one. And the most apparent incarnation of the unity of Love and Beauty is Art.
