Abstract

In this paper practical reasoning is understood in the Aristotelian sense as reasoning leading to action or to an intention to do something. Georg Henrik von Wright and a number of other philosophers have tried to assimilate certain forms of such reasoning to deductive reasoning. Many examples of practical reasoning, including some examples given by Aristotle, do not fit a deductive or quasi‐deductive model. It is argued that instances of good practical reasoning often resemble abductive rather than deductive or inductive reasoning, and that the principles governing abduction, including the Principle of Economy, are applicable to practical reasoning.
