Essentiality of things

Abstract

The choice of an observation level and an exemplar are the first two steps in the process which ultimately leads to the design of an artificial object. Nevertheless, the choice of an exemplar is not the final conclusive defining moment of what will be done. As soon as the problem of the delimitation of the exemplar—which we discussed in the previous section—is solved, we are faced with a new and decisive step. This moment could be defined as the choice, or the attribution, of an essential performance for the exemplar.
