interrelated aspects of self: the material self (all those aspects of material existence in which we feel a strong sense of ownership, our bodies, our families, our possessions), the social self (our felt social relations), and the spiritual self (our feelings of our own subjectivity)". In 1956 psychologist and social philosopher Erich Fromm proposed that loving oneself is different from being arrogant, conceited or egocentric, meaning that instead caring about oneself and taking responsibility for oneself. Fromm proposed a re-evaluation of self-love in more positive sense, arguing that in order to be able to truly love another person, a person first needs to love oneself in the way of respecting oneself and knowing oneself (e.g. being realistic and honest about one's strengths and weaknesses). In the 1960s, Erik H. Erikson similarly wrote of a post-narcissistic appreciation of the value of the ego, while Carl Rogers saw one result of successful therapy as the regaining of a quiet sense of pleasure in being one's own self. Self-love or self-worth was defined in 2003 by Aiden Gregg and Constantine Sedikides as "referring to a person's subjective appraisal of himself or herself as intrinsically positive or negative". Mental health Lack of self-love increases risk of suicide according to the American Association of Suicidology. The association conducted a study in 2008 which researched the impact of low self-esteem and lack of self-love and its relation to suicidal tendencies and attempts. They defined self-love as being "beliefs about oneself (self-based self-esteem) and beliefs about how other people regard oneself (other-based self-esteem)". It concluded that "depression, hopelessness, and low self-esteem are implications of vulnerability factors for suicide ideation" and that "these findings suggest that even in the context of depression and hopelessness, low self-esteem may add to the risk for suicide ideation". Promotion History Self-love was first promoted by the Beat Generation of the 1950s and in the early years of the Hippie era of the 1960s. After witnessing the devastating consequences of World War II and having troops still fighting in the Vietnam War, western (especially North American) societies began promoting "peace and love" to help generate positive energy and to promote the preservation of dissipating environmental factors, such as the emergence of oil pipelines and the recognition of pollution caused by the greenhouse effect. These deteriorating living conditions caused worldwide protests that primarily focused on ending the war, but secondarily promoted a positive environment
