Contributions of artists vs. scientists

Science and art are two main streams of knowledge accumulated from ancient times by human beings. They have their own characteristics and provide to the society their contributions, which benefit the world in which we live. Some people think that the contributions of scientists are higher than the artists. Before I give my opinion, I want to see the two sides first.  

Science is defined mostly as the knowledge related to the natural world. I think most of its domains are involved in the material things, such as food, housing, clothing, transport, etc. It is usually easy for people to feel the existence and progress of science, because it is usually taking place around us and becoming more manifest. In past, science has leaded us to make great advance in our life, and I believe in future, it will continue to improve the world we live now. 

Art is more related to our spiritual world. It has long history, too. It has nearly developed coincided with the science. Art help us to know clear about ourselves and it can help us get rid of negative mood, which may restrain our work effectiveness. Many people admit that art can nourish their mind and make their spiritual outlook better. In this respect, art is a good complement to science.  

Through above statements, I can hardly tell which one is more valued in terms of the contribution to the society. Because they are both imperative for us to build the world. The history of human has prove this. So I do not think it is wise and safe to say that one of them is more important than the other one. As far as I am concerned, I think they both weigh heavily with regard to the contributions to the society.
