Aristotle's ethical writings are among the most influential in the history of Western thought. Key to these writings is the idea that some people better understand how they should act in order to lead successful lives as part of their communities. Their knowledge is called practical wisdom (phronēsis). Some of what Aristotle says suggests that this kind of knowledge is intuitive or unreflective, but at other times it seems abstruse and theoretical. Aristotle's Practical Epistemology presents a novel interpretation of Aristotle's influential account of practical wisdom (phronēsis) by situating the topic within his broader theory of ethical knowledge. Interpreters have long struggled to make sense of the disparate features Aristotle seems to attribute to practical wisdom, particularly its role in bringing about individual choices and actions in the domain of ethical action, of theoretical wisdom (sophia) and craft (tekhnē). Dhananjay Jagannathan contends that these features can be united when we see that phronēsis is a distinctively practical form of understanding.
