The ἀγαθόν is met in a knowing-the-way-around (Auskenntnis) something where there is no question of τέχνη happening occasionally alongside a concern (Besorgen). Τέχνη belongs to the sense of concern (Sinn des Besorgens). “I am concerned about something.” It is said, thereby, that I know my way around within the context of that which I anticipate, that the what of concern is in sight, is explicitly there, that I know my way around in that which is conducive. The ἀγαθόν as such is encountered in τέχνη, specifically in such a way that it is explicit. That is an indication that, as ἀνθρώπινον ἀγαθόν, it deals with a τέχνη to which a concern belongs, which concern constitutes the being of human beings. It is an indication that we will find the ἀνθρώπινον ἀγαθόν in a characteristic knowing-the-way-around of living itself. Aristotle designates this τέχνη as πολιτική. Therein lies the fact that he sees the knowing-one’s-way-around of living (Sichauskennen des Lebens) itself as πολιτική, being-there as being-with-one-another (Miteinandersein). (GA18MT:49)

How are we to understand that for τέχνη an ἀρετή is possible? In the deliberation (Überlegen) of know-how (Sich-Auskennen) there are various degrees of development. Τέχνη can presume things and concede things. Trial and error (Probieren) are proper to it. Through τέχνη, one discovers whether something works or not. The more τέχνη risks failure, the more secure it will be in its procedure. It is precisely through failure that certitude is formed. It is precisely the one who is not ingrained in a definite technique, a set routine, but again and again starts anew and cuts through rigid procedure, who acquires the correct possibility of know-how, has at his disposal the proper kind of the ἀληθεύειν that corresponds to τέχνη, and acquires more and more of that kind of uncovering (Aufdeckens).
