NarcissismNarcissism is a self-centered personality style characterized as having an excessive preoccupation with oneself and one's own needs, often at the expense of others. Narcissism exists on a continuum that ranges from normal to abnormal personality expression. While there exist normal, healthy levels of narcissism in humans, there are also more extreme levels of narcissism, being seen particularly in people who are self-absorbed, or people who have a pathological mental illness like narcissistic personality disorder (NPD).
SelfishnessSelfishness is being concerned excessively or exclusively, for oneself or one's own advantage, pleasure, or welfare, regardless of others. Selfishness is the opposite of altruism or selflessness; and has also been contrasted (as by C. S. Lewis) with self-centeredness. The implications of selfishness have inspired divergent views within religious, philosophical, psychological, economic, and evolutionary contexts.
EgoismEgoism is a philosophy concerned with the role of the self, or , as the motivation and goal of one's own action. Different theories of egoism encompass a range of disparate ideas and can generally be categorized into descriptive or normative forms. That is, they may be interested in either describing that people do act in self-interest or prescribing that they should. Other definitions of egoism may instead emphasise action according to one's will rather than one's self-interest, and furthermore posit that this is a truer sense of egoism.
Self-loveSelf-love, defined as "love of self" or "regard for one's own happiness or advantage", has been conceptualized both as a basic human necessity and as a moral flaw, akin to vanity and selfishness, synonymous with amour-propre, conceitedness, egotism, narcissism, et al. However, throughout this century self-love has adopted a more positive connotation through pride parades, Self-Respect Movement, self-love protests, the hippie era, the modern feminist movement (3rd & 4th wave), as well as the increase in mental health awareness that promotes self-love as intrinsic to self-help and support groups working to prevent substance abuse and suicide.
Ethical egoismIn ethical philosophy, ethical egoism is the normative position that moral agents ought to act in their own self-interest. It differs from psychological egoism, which claims that people can only act in their self-interest. Ethical egoism also differs from rational egoism, which holds that it is rational to act in one's self-interest. Ethical egoism holds, therefore, that actions whose consequences will benefit the doer are ethical. Ethical egoism contrasts with ethical altruism, which holds that moral agents have an obligation to help others.
AltruismAltruism is the principle and practice of concern for the well-being and/or happiness of other humans or animals. While objects of altruistic concern vary, it is an important moral value in many cultures and religions. It may be considered a synonym of selflessness, the opposite of selfishness. The word altruism was popularized (and possibly coined) by the French philosopher Auguste Comte in French, as altruisme, for an antonym of egoism. He derived it from the Italian altrui, which in turn was derived from Latin alteri, meaning "other people" or "somebody else".
Self-esteemSelf-esteem is confidence in one's own worth, abilities or morals. Self-esteem encompasses beliefs about oneself (for example, "I am loved", "I am worthy") as well as emotional states, such as triumph, despair, pride, and shame. Smith and Mackie (2007) defined it by saying "The self-concept is what we think about the self; self-esteem, is the positive or negative evaluations of the self, as in how we feel about it (see Self).
Narcissistic personality disorderNarcissistic personality disorder (NPD) is a personality disorder that involves self-loathing, a fragile self-esteem and compensatory self-importance. It is also associated with primitive defence mechanisms and a superiority complex that protect the individual psychologically. The conduct of one's life is often disingenuous in the patient population and the avoidance of the appearance of inferiority (dependence) is common. Research has pointed that agreeableness is exceedingly low translating to lack of empathy and altruism.
