Pride is defined by Merriam-Webster as "reasonable self-esteem" or "confidence and satisfaction in oneself". Oxford defines it as "the quality of having an excessively high opinion of oneself or one's own importance." This may be related to one's own abilities or achievements, positive characteristics of friends or family, or one's country. Richard Taylor defined pride as "the justified love of oneself", as opposed to false pride or narcissism. Similarly, St. Augustine defined it as "the love of one's own excellence", and Meher Baba called it "the specific feeling through which egoism manifests."
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. Some social psychologists identify the nonverbal expression of pride as a means of sending a functional, automatically perceived signal of high social status.
Pride is sometimes viewed as corrupt or as a vice, sometimes as proper or as a virtue. With a positive connotation, pride refers to a 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.
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.
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 Hebrew Bible. In Judaism, pride is called the root of all evil. When viewed as a virtue, pride in one's abilities is known as virtuous pride, the greatness of soul or magnanimity, but when viewed as a vice it is often known to be self-idolatry, sadistic contempt, vanity or vainglory.
