This book concerns a metaphysical definition of artifacts, taken as a key term of the philosophy of technology. Due to the fact that classical determinations are not only insufficient explicating the term but also inapplicable to real artifacts, the work tries to develop a concept of "artifacts" using the thought of truth given by Martin Heidegger. In so far a hermeneutic interpretation of his oeuvre shows us, that truth actually is an object-generating happening. Thats why an analysis of forms of judgments allows the description of factic things. Assuming that there are theoretical judgments concerning technique - wherefore technique is an historically contingent kind of metaphysics - artifacts are given as geometrical universals, meaning terms, without being able to subsume thought-independend individuals, unless artifacts exceptionally are known as subjects of practical philosophy.
