Self-denial (also called self-abnegation and self-sacrifice) refers to altruistic abstinence – the willingness to forgo personal pleasures or undergo personal trials in the pursuit of the increased good of another. Various religions and cultures take differing views of self-denial, some considering it a positive trait and others considering it a negative one. According to some Protestants, self-denial is considered a superhuman virtue only obtainable through Jesus. Some critics of self-denial suggest that self-denial can lead to self-hatred and claim that the self-denial practiced in Judaism has created self-hating Jews.
Religion and self-denial
Self-denial can constitute an important element of religious practice in various belief systems. An examplification is the self-denial advocated by several Christian confessions where it is believed to be a mean of reaching happiness and a deeper religious understanding, sometimes described as 'becoming a true follower of Christ'. The foundation of self-denial in the Christian context is based the recognition of a higher God-given will, which the Christian practicer choose to adhere to, and prioritize over his or her own will or desires. This can in daily life be expressed by renounciation of certain physically pleasureable, yet from a religious stand-point inappropriate activities, sometimes referred to as 'desires of the flesh', which e.g. could entail certain sexual practices and overindulgant eating or drinking. In the Christian faith Jesus is often mentioned as an positive example of self-denial, both in relation to the deeds performed during his life, as well as the sacrifice attributed to his death.
Based on sex
Self-denial in women is linked to cultural definitions of femininity which women have internalized to such an extent that self-abnegation had become basic to women's experience. Judith Plaskow observed this and argued that it was more linked to women then men because they were to follow this Christian virtue because of their detriment. Women are seen in a domestic perspective and self-denial puts all things women were once exposed to the side so they can be committed to their marriage and family. The way women are portrayed hasn't changed much throughout the years because the patriarchal perspective continues to be present. Through self-denial women have to sacrifice their interests and goals to satisfy not only family, but many times social norms. They are not allowed to be independent but more so are trapped to be the individual they are expected to be. However, in men, this is different. Masculinity is linked to self-denial when put in a male perspective. Men's self-denial is both a source of men's existential alienation and part of the infrastructure of men's power. When men go through self-denial it is interpreted as self-improvement as put by the book Manliness in which they emphasize self-denial as a comparison to the image of the goal of Superman in "What does not kill me makes me stronger.""
There is evidence brief periods of fasting, a denial of food, can be beneficial to health in certain situations. Self denial is sometimes related to inhibitory control and emotional self-regulation, the positives of which are dealt with in those articles.
Others argue self-denial involves avoidance and holding back of happiness and pleasurable experiences from oneself that is only damaging to other people. Some argue it is a form of micro-suicide because it is threatening to an individual's physical health, emotional well-being, or personal goals.
