Illustrating the centrality of skill within ancient ethics, including Socrates’ search for expertise in virtue, the Republic’s ‘craft of justice’, Aristotle’s delineation of the politike techne, the Stoics’ ‘art of life’ and ancient Chinese ethics, this collection shows how skill has been an ethical touchstone from the beginning of philosophical thought. Divided into six sections – on Plato, Aristotle, the Stoics, Mencius and Xunzi, the Mohists and Zhuangzi, and comparative perspectives – world-leading philosophers explore the significance of skill according to traditional figures, as well as lesser-known philosophers such as Carneades and Antipater, and texts such as the Zhuangzi. In doing so, the seventeen contributors illustrate how skill, expertise and ‘know how’ are essential to and foundational within ancient ethical thought. As the first collection to foreground skill as central to ancient Greek, Roman and Chinese ethics, this is an essential resource for anyone interested in the value of cross-cultural philosophy today.
