[I really don't have much clue what to do with this preface. The plan for the preface is as follows. Every now and then I will just throw it away and write another. Hopefully, sometime, I will write one that I like, and then keep it.]
This is the first of two volumes in which I hope to give a first account of a philosophical point of view which I call Positive Philosophy. In this preface I describe the scope of the enterprise and the way in which it is divided across the two volumes, by reference to the divisions in the philosophy of Aristotle.
To a first approximation the first volume is concerned with theoretical philosophy, the second with practical philosophy. Of these, theoretical philosophy is concerned with knowledge, with logic, mathematics and empirical science, and practical philosophy with action, with ethics, politics and economics.
These two categories, the theoretical and the practical, appear in Aristotle, but are not exhaustive of his work. Two other divisions are the organon, which consists of Aristotle's writings on or related to logic, conceived rather more broadly than today, and productive science, which involve arts and crafts, or more generally, how to make or do things. In this two-fold division of positive philosophy, the first volume, theoretical philosophy, includes also logic. In addition to this augmented theoretical philosophy, and the second volume on practical philosophy there is an important element of what Aristotle might have thought productive philosophy, concerned with a kind of production which I think of primarily as engineering, albeit primarily software engineering.
