The final part of our discussion declares that it will be the most serious, since it deals with human actions, which are of direct concern to everyone; no one is unfamiliar with or indifferent to such a topic. In fact, it is so natural for people to relate everything to action that they will always consider that part of any systematic discussion which concerns deeds to be the culmination of the whole work, at least to the extent that it is of interest to them, and will accordingly pay serious attention to this part, if to no other. – In the present context, the discussion that follows is what is generally referred to as practical philosophy, in contrast to the theoretical philosophy that has so far been our concern. But in my opinion, philosophy is always theoretical, since what is essential to it is that it treats and investigates its subject-matter (whatever that may be) in a purely contemplative manner, describing without prescribing. On the other hand, for it to become practical, guide action, shape character – these are long-standing demands, and mature insight should encourage us to give them up once and for all.
