亞里士多德的實踐倫理學概念可以從亞里士多德在他的修辭學中闡明的實踐推理的論述中得到，這對我們理解實踐倫理學的本質和局限性具有重要的意義。實踐倫理學這一概念的一個重要特征是，它對行為人形成和維持道德承諾的復雜方式作出反應，這對應用倫理學中有關倫理學方法的辯論具有重要意義。特別是，這一特性使我們能夠將詭辯、敘事和原則主義理解為相互支持的道德探究模式，而不是相互排斥的、發散的道德方法。因此，亞里士多德的實踐倫理學概念為實踐倫理學家建立穩定的、現實的自我理解掃清了概念上的共同基礎。

An Aristotelian conception of practical ethics can be derived from the account of practical reasoning that Aristotle articulates in his Rhetoric and this has important implications for the way we understand the nature and limits of practical ethics. An important feature of this conception of practical ethics is its responsiveness to the complex ways in which agents form and maintain moral commitments, and this has important implications for the debate concerning methods of ethics in applied ethics. In particular, this feature enables us to understand casuistry, narrative, and principlism as mutually supportive modes of moral inquiry, rather than divergent and mutually exclusive methods of ethics. As a result, an Aristotelian conception of practical ethics clears the conceptual common ground upon which practical ethicists can forge a stable and realistic self-understanding.
