This dissertation is a study of the relation between Aristotle’s ethics and the crafts (or technai). My thesis is that Aristotle’s argument is at key points shaped by models proper to the crafts, this shaping being deeper than is generally acknowledged, and philosophically more problematic. Despite this, I conclude that the arguments I examine can, if revised, be upheld. The plan of the dissertation is as follows – Preface: The relation of my study to the extant secondary literature; Introduction: The (...) pre-Platonic concept of technē, as evidenced in Greek philosophical and literary sources, in particular the early Hippocratic corpus; Chapter one: The Platonic concept of technē, followed by an investigation of whether Plato affirms a virtue-technē in the Protagoras and Republic; Chapter two: Aristotle’s concept of technē, followed by scrutiny of his arguments in NE VI.5 against a virtue-technē, and of his analyses of slavery and deliberation; Chapter three: An exposition of Aristotle’s function argument, followed by a dominantist interpretation of it, and an explanation of dominantism as in part a technē-influenced doctrine; Chapter four: An examination of Aristotle’s ethical mean and its problems, with a diagnosis of these in terms of influence by the Philebus, and by paradigms derived from the crafts; Chapter five: Argument that Aristotle’s theory of habituation suffers from two significant opacities, these being a function of influence both by the Republic, and by models of craft-learning; Conclusion: Response to key objection; Aristotle’s ethics revised, defended.
