PHIL 21509/31509 Practical Rationality
Humans are said to be rational animals. What does rationality, understood as a capacity, consist in? And what is practical rationality, understood as a qualified way of thinking, feeling, and acting? – In this course we are going to consider a roughly Aristotelian framework for answering these and related questions. The place of reason in human nature is characterized by a complex teleology: its employment is both purpose and instrument. To make use of reason is, centrally, to infer, i.e. to think and act for reasons. The roles of reasons are various: they validate, justify, prompt and guide, explain … To act on a reason is, typically, to do something for the sake of some end. This is so, in particular, in the context of more or less technical reasoning. But the most basic and ultimate reasons, the ones by heeding which we act justly or unjustly and, more generally, well or badly, seem not to be of this form. How then do they enter the constitution of a good human life?
