亞里士多德的實(shí)踐倫理學(xué)概念可以從亞里士多德在他的修辭學(xué)中闡明的實(shí)踐推理的論述中得到，這對(duì)我們理解實(shí)踐倫理學(xué)的本質(zhì)和局限性具有重要的意義。實(shí)踐倫理學(xué)這一概念的一個(gè)重要特征是，它對(duì)行為人形成和維持道德承諾的復(fù)雜方式作出反應(yīng)，這對(duì)應(yīng)用倫理學(xué)中有關(guān)倫理學(xué)方法的辯論具有重要意義。特別是，這一特性使我們能夠?qū)⒃庌q、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(fā)散的道德方法。因此，亞里士多德的實(shí)踐倫理學(xué)概念為實(shí)踐倫理學(xué)家建立穩(wěn)定的、現(xiàn)實(shí)的自我理解掃清了概念上的共同基礎(chǔ)。

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.
