Pride is an inwardly directed emotion that carries two antithetical meanings. With a negative connotation pride refers to a foolishly and irrationally corrupt sense of one's personal value, status or accomplishments, used synonymously with hubris. With a positive connotation, pride refers to a humble and content sense of attachment toward one's own or another's choices and actions, or toward a whole group of people, and is a product of praise, independent self-reflection, and a fulfilled feeling of belonging.
Philosophers and social psychologists have noted that pride is a complex secondary emotion which requires the development of a sense of self and the mastery of relevant conceptual distinctions (e.g. that pride is distinct from happiness and joy) through language-based interaction with others.[2] Some social psychologists identify the nonverbal expression of pride as a means of sending a functional, automatically perceived signal of high social status.[3] In contrast, pride could also be defined as a lowly disagreement with the truth. One definition of pride in the former sense comes from St. Augustine: "the love of one's own excellence".[4] A similar definition comes from Meher Baba: "Pride is the specific feeling through which egoism manifests."[5]
Pride is sometimes viewed as corrupt or as a vice, sometimes as proper or as a virtue. While some philosophers such as Aristotle (and George Bernard Shaw) consider pride (but not hubris) a profound virtue, some world religions consider pride's fraudulent form a sin, such as is expressed in Proverbs 11:2 of the Old Testament. In Christianity, pride is one of the Seven Capital Sins. When viewed as a virtue, pride in one's abilities is known as virtuous pride, greatness of soul or magnanimity, but when viewed as a vice it is often known to be self-idolatry, sadistic contempt, vanity or vainglory. Pride can also manifest itself as a high opinion of one's nation (national pride) and ethnicity (ethnic pride)
