In the study of ethics and morality, selfishness is usually considered bad. In contrast, acts of selflessness are praised. Wider debate about it, however, such as in philosophy, psychology and economics, has shown that scholars have had many different opinions about its value and consequences. In most major religions, selfishness is considered an immoral or bad habit. In Christianity, it is associated with pride, often considered the worst of the Seven deadly sins. Aristotle condemned men who would only try to profit themselves; but he approved of those who would try to gain the praise from others that he deserved.
