Love is a condition or phenomenon of emotional primacy, or absolute value. Love generally includes an emotion of intense attraction to either another person, a place, or thing; and may also include the aspect of caring for or finding identification with those objects, including self-love. Love can describe an intense feeling of affection, an emotion or an emotional state. In ordinary use, it usually refers to interpersonal love, an experience usually felt by a person for another person. Love is commonly considered impossible to define.

The concept of love, however, is subject to debate. Some deny the existence of love, calling it a recently invented abstraction. Moreover, approximately 13 percent of cultures reportedly have no word for love.[1] Others maintain that love exists but is indefinable; being a quantity which is spiritual, metaphysical, or philosophical in nature. Love is one of the most common themes in art. An unfinished debate about the authenticity of love as other-regard began with Friedrich Nietzsche's charge that love is merely an ideology constructed by the weak to mask "resentment" about their lack of power. Critics of Nietzsche's view find gratuitous his assumptions that self-interest and the "will to power" overshadow all other concerns.
