Altruism /ˈæltruːɪzəm/ is a concern for the welfare of others. It is a traditional virtue in many cultures, and a core aspect of various religious traditions, though the concept of 'others' toward whom concern should be directed can vary among cultures and religions. Altruism is the opposite of selfishness.
Altruism can be distinguished from feelings of loyalty and duty. Altruism is a motivation to provide something of value to a party who must be anyone but the self, while duty focuses on a moral obligation towards a specific individual (for example, a god, a king), or collective (for example, a government). Some individuals may feel both altruism and duty, while others may not. Pure altruism consists of giving something of value (a reward or benefit) with no expectation of any compensation or benefits, either direct, or indirect (for instance from recognition of the giving).
The term altruism may also refer to an ethical doctrine that claims that individuals are morally obliged to benefit others. Used in this sense, it is the opposite of egoism.
