Abstract: Science and technology are the primary productive forces, which shows that the modern science and technology are the independent elements of productive forces and an important impetus for the social development. However, they are not decisive. The revolution of modern science and technology witnessed its beginning in America due to various objective factors, and it has radiated to other countries. It has brought various advantages to human beings as well as great challenges for human existence and development. In contemporary society, human beings are more dependent on science and technology than any other times. This makes us to form a critical, reasonable and reflective science and technology view more urgently than ever before.
