 By the Han period, benevolence, righteousness, ritual propriety, wisdom and trustworthiness began to be considered as a complete set of human virtues, corresponding with other quintets of phenomena used to describe the natural world. Some texts described a level of moral perfection, as with the sages of antiquity, as unifying all these virtues. Prior to this, it is unclear whether the possession of a particular virtue entailed having all the others, although benevolence was sometimes used as a more general term for a combination of one or more of the other virtues (e.g., Analects 17.6). At other times, Confucius presented individual virtues as expressions of goodness in particular domains of life. Early Confucius dialogues are embedded in concrete situations, and so resist attempts to distill them into more abstract principles of morality. As a result, descriptions of the virtues are embedded in anecdotes about the exemplary individuals whose character traits the dialogues encourage their audience to develop. Confucius taught that the measure of a good action was whether it was an expression of the actor’s virtue, something his lessons share with those of philosophies like Aristotle’s that are generally described as “virtue ethics”. A modern evaluation of the teachings of Confucius as a “virtue ethics” is articulated in Bryan W. Van Norden’s Virtue Ethics and Consequentialism in Early Chinese Philosophy, which pays particular attention to analogies between the way of Confucius and Aristotle’s “good life”. The nature of the available source materials about Confucius, however, means that the diverse texts from early China lack the systematization of a work like Aristotle’s Nicomachean Ethics.
