Virtue (Latin virtus; Greek 
				
				άρετή) is moral excellence of a person. A virtue is a trait 
				valued as being good. The conceptual opposite of virtue is vice.
				
				According to its etymology the word virtue (Latin virtus) 
				signifies manliness or courage. Taken in its widest sense virtue 
				refers to excellence, just as vice, its contrary, denotes the 
				absence of such. In its strictest meaning, however, as used by 
				moral philosophers and theologians, virtue is an operative habit 
				essentially good, as distinguished from vice, an operative habit 
				essentially evil. The four cardinal (hinge) virtues are Justice, 
				Courage, Wisdom, and Moderation. These were enumerated by the 
				Greek philosophers. The three supernatural virtues of Faith, 
				Hope and (unselfish) Love are part of the tradition of Pauline 
				Christianity, Judaism and Islam.
				
				Virtue can also be meant in another way. Virtue can either have 
				normative or moral value; i.e. the virtue of a judge is to 
				justly convict criminals, the virtue of an excellent judge is to 
				specialize in justly convicting criminals (this is its normative 
				value) vs. the virtues of reason, prudence, chastity, etc. 
				(which have moral value).
				
				In the Greek it is more properly called 
				ηθικη
				
				άρετή
				(ēthikē aretē). It is "habitual 
				excellence". It is something practiced at all times. The virtue 
				of perseverance is needed for all and any virtue since it is a 
				habit of character and must be used continuously in order for 
				any person to maintain oneself in virtue.
