Virtue, in short, is a desire for honourable things. Aristotle defined the virtue as habits of acting or dispositions to act in certain ways. In China the term Dé is probably the closest modern English equivalent that means ‘virtue’ in the sense of ‘personal character,’ ‘inner strength,’ ‘virtuosity,’ or ‘integrity.’ Chinese character Dé, written as 德, is composed of the radical彳followed by the number ‘fourteen’ or shí sì (十四) over ‘one’ or yī (一) ‘heart / mind’ or xīn (心). The simple meaning is that one has to have a big heart for fourteen people.
