This chapter discusses Hans Blumenberg's first extensive discussion of the concept of the life-world, “Phenomenological Aspects on Life-World and Technization” (1963). The problem of technology is such a characteristic element of modern, contemporary thought, even though the problem of technology has not yet been clearly distinguished from the problems of technology. The century or so of what called itself philosophy of technology has produced a sense of obviousness of what in the case of technology was “the thing itself” — a sense that is already highly suspicious. According to Ernst Kapp, “all of human history, upon close scrutiny, ultimately resolves into the history of the invention of better tools.” Correspondingly, the term “technology” evokes a colorful series of images: devices, vehicles, propulsion motors, storage units, manual and automatic instruments, and so forth — in short, a universe of things that are at work all around us, whose complete classification has often been attempted to little success, whose unifying factor, which the concept “technology” signifies, seems impossible to grasp, and which is therefore rendered unquestionable in a nominalistic way. With the appropriate conceptual frugality, “technization” is then to be understood as the constant multiplication and condensation of this thing-world.
