egotism

n. conceit, self-centeredness, selfishness, exaggerated feelings of self-importance, vanity

Egotism is the doctrine that individual self-interest is the appropriate motive and valid end of all conscious action. Egotism manifests itself as excessive rationalization, denial, &/or narcissism, as well as the inordinate concern for oneself or a tendency to speak or write of oneself boastfully and at great length. Egotism may also be coupled with an inflated sense of one's own importance, at the denial of others. This conceit is a character trait describing a person who acts to gain values in an amount greater than that of the values he/she gives to others. Egotism is often accomplished by exploiting the altruism, irrationality and ignorance of others, as well as utilizing coercive force and/or fraud.
