PhilosophyPhilosophy (love of wisdom in ancient Greek) is a systematic study of general and fundamental questions concerning topics like existence, reason, knowledge, values, mind, and language. It is a rational and critical inquiry that reflects on its own methods and assumptions. Historically, many of the individual sciences, like physics and psychology, formed part of philosophy. But they are considered separate academic disciplines in the modern sense of the term.
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".
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.
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.
EmpathyEmpathy is the capacity to understand or feel what another person is experiencing from within their frame of reference, that is, the capacity to place oneself in another's position. Definitions of empathy encompass a broad range of social, cognitive, and emotional processes primarily concerned with understanding others (and others' emotions in particular). Types of empathy include cognitive empathy, emotional (or affective) empathy, somatic empathy, and spiritual empathy.
