Abstract
A Criticism of Poiëtical Reason. Remarks on Epistemological Philosophy of Technological Shaping. According to Aristoteles human reason can be divided into three independent properties: ϑεωρια,πραξισ, and πoιησισ. The latter is required for the technological construction of actuality. Scrutinizing to the conception of μιμησισ it can be figured out that technological acting intends a representation of truth, not an imitation of nature. The concept of nature developed by sciences of modern times is discussed in its lawful disposition. To give some features of an epistemological philosophy of technological shaping first the difference between technological rules and laws of nature is examined. Second, three attributes of technological sciences in distinction to natural sciences are described. Finally, some shaping rules used by engineering sciences are presented. These rules need an epistemological investigation put through other wise than the philosophy of science.
