Abstract
Since ancient times philosophy has dealt with the relation between technology and man. Nowadays this is especially true in the context of the philosophy of technology. Technology is interpreted as an anthropological constant to construct an environment in which man can survive. Acting in the field of technology is to act rationally with a purpose, i.e., in the framework of a means-end relation, and it is employed for coping with experiences (Widerfahrnisse) by means of using tools. Like technology, language can be reconstructed as a symbolic form and thus as a technological means, as a tool so that the employment of metaphors can also be described as an employment of tools. Using technology has effects on man as well as on his self-image. Thus, philosophy of technology creates different ideas of man, which have to become subject to ethical discourses
