Hans Jonas 's responsibility ethics is an important achievement of modern technology criticism and ethical theory innovation. The maturity of Jonas's ethical thought has gone through three main stages, namely, the critique of modern technology, the reflection of traditional ethics and the construction of the " Future-oriented " Responsibility Ethics. Jonas's criticism of modern technology not only has a strong epochal character but also carries on the spirit of social criticism since Marx. His insight into the traditional ethics theory and the ethical characteristics of the technical age constituted the background of the Responsibility ethics. Jonas's responsibility ethics is not only the return of "responsibility" spirit in ethics but also the dimension of "Future", which is the characteristic of his theory. Through criticism, reflection and construction, Jonas formed this kind of asymmetrical ethics thought of "Future-oriented" Responsibility and faced the challenge of modern technology.
