Suffering, or pain in a broad sense,See 'Terminology'. See also the entry 'Pleasure' in Stanford Encyclopedia of Philosophy, which begins with this paragraph: "Pleasure, in the inclusive usages most important in moral psychology, ethical theory, and the studies of mind, includes all joy and gladnessall our feeling good, or happy. It is often contrasted with similarly inclusive pain or suffering, which is similarly thought of as including all our feeling bad." It should be mentioned that most encyclopedias, like the one mentioned above and Britannica, do not have an article about suffering and describe pain in the physical sense only. may be an experience of unpleasantness or aversion, possibly associated with the perception of harm or threat of harm in an individual.For instance, Wayne Hudson in Historicizing Suffering, Chapter 14 of Perspectives on Human Suffering (Jeff Malpas and Norelle Lickiss, editors, Springer, 2012) : "According to the standard account suffering is a universal human experience described as a negative basic feeling or emotion that involves a subjective character of unpleasantness, aversion, harm or threat of harm to body or mind (Spelman 1997; Cassell 1991)." Suffering is the basic element that makes up the negative valence of affective phenomena. The opposite of suffering is pleasure or happiness.

Suffering is often categorized as physicalExamples of physical suffering: pain of various types, excessive heat, excessive cold, itching, hunger, thirst, nausea, air hunger, sleep deprivation. Other examples are given by L. W. Sumner, on p. 103 of Welfare, Happiness, and Ethics: "Think for a moment of the many physical symptoms which, when persistent, can make our lives miserable: nausea, hiccups, sneezing, dizziness, disorientation, loss of balance, itching, 'pins and needles', 'restless legs', tics, twitching, fatigue, difficulty in breathing, and so on." or mental.Mental suffering can also be called psychological or emotional (see Psychological pain). Examples of mental suffering: depression (mood) / hopelessness, grief, sadness / loneliness / heartbreak, disgust, irritation, anger, jealousy, envy, craving or yearning, frustration, anguish, angst, fear, anxiety / panic, shame / guilt, regret, embarrassment / humiliation, restlessness. It may come in all degrees of intensity, from mild to intolerable. Factors of duration and frequency of occurrence usually compound those of intensity. Attitudes toward suffering may vary widely, in the sufferer or other people, according to how much it is regarded as avoidable or unavoidable, useful or useless, deserved or undeserved.

Suffering occurs in the lives of sentient beings in numerous manners, often dramatically. As a result, many fields of human activity are concerned with some aspects of suffering. These aspects may include the nature of suffering, its processes, its origin and causes, its meaning and significance, its related personal, social, and cultural behaviors, its remedies, management, and uses.

Terminology The word suffering is sometimes used in the narrow sense of physical pain, but more often it refers to psychological pain, or more often yet it refers to pain in the broad sense, i.e. to any unpleasant feeling, emotion or sensation. The word pain usually refers to physical pain, but it is also a common synonym of suffering. The words pain and suffering are often used both together in different ways. For instance, they may be used as interchangeable synonyms. Or they may be used in 'contradistinction' to one another, as in "pain is physical, suffering is mental", or "pain is inevitable, suffering is optional". Or they may be used to define each other, as in "pain is physical suffering", or "suffering is severe physical or mental pain".

Qualifiers, such as physical, mental, emotional, and psychological, are often used to refer to certain types of pain or suffering. In particular, mental pain (or suffering) may be used in relationship with physical pain (or suffering) for distinguishing between two wide categories of pain or suffering. A first caveat concerning such a distinction is that it uses physical pain in a sense that normally includes not only the 'typical sensory experience of physical pain' but also other unpleasant bodily experiences including air hunger, hunger, vestibular suffering, nausea, sleep deprivation, and itching. A second caveat is that the terms physical or mental should not be taken too literally: physical pain or suffering, as a matter of fact, happens through conscious minds and involves emotional aspects, while mental pain or suffering happens through physical brains and, being an emotion, involves important physiological aspects.

The word unpleasantness, which some people use as a synonym of suffering or pain in the broad sense, may refer to the basic affective dimension of pain (its suffering aspect), usually in contrast with the sensory dimension, as for instance in this sentence: "Pain-unpleasantness is often, though not always, closely linked to both the intensity and unique qualities of the painful sensation."Donald D. Price, Central Neural Mechanisms that Interrelate Sensory and Affective Dimensions of Pain , ‘’Molecular Interventions’’ 2:392–403 (2002). Other current words that have a definition with some similarity to suffering include distress, unhappiness, misery, affliction, woe, ill, discomfort, displeasure, disagreeableness.

Philosophy

Ancient Greek philosophy Many of the Hellenistic philosophies addressed suffering.

In Cynicism suffering is alleviated by achieving mental clarity or lucidity (ἁτυφια: atyphia), developing self-sufficiency (αὐτάρκεια: autarky), equanimity, arete, love of humanity, parrhesia, and indifference to the vicissitudes of life (adiaphora).

For Pyrrhonism, suffering comes from dogmas (i.e. beliefs regarding non-evident matters), most particularly beliefs that certain things are either good or bad by nature. Suffering can be removed by developing epoche (suspension of judgment) regarding beliefs, which leads to ataraxia (mental tranquility).

Epicurus (contrary to common misperceptions of his doctrine) advocated that we should first seek to avoid suffering (aponia) and that the greatest pleasure lies in ataraxia, free from the worrisome pursuit or the unwelcome consequences of ephemeral pleasures. Epicureanism's version of Hedonism, as an ethical theory, claims that good and bad consist ultimately in pleasure and pain.

For Stoicism, the greatest good lies in reason and virtue, but the soul best reaches it through a kind of indifference (apatheia) to pleasure and pain: as a consequence, this doctrine has become identified with stern self-control in regard to suffering.

Modern philosophy

Jeremy Bentham developed hedonistic utilitarianism, a popular doctrine in ethics, politics, and economics. Bentham argued that the right act or policy was that which would cause "the greatest happiness of the greatest number". He suggested a procedure called hedonic or felicific calculus, for determining how much pleasure and pain would result from any action. John Stuart Mill improved and promoted the doctrine of hedonistic utilitarianism. Karl Popper, in The Open Society and Its Enemies, proposed a negative utilitarianism, which prioritizes the reduction of suffering over the enhancement of happiness when speaking of utility: "I believe that there is, from the ethical point of view, no symmetry between suffering and happiness, or between pain and pleasure. ... human suffering makes a direct moral appeal for help, while there is no similar call to increase the happiness of a man who is doing well anyway." David Pearce, for his part, advocates a utilitarianism that aims straightforwardly at the abolition of suffering through the use of biotechnology (see more details below in section Biology, neurology, psychology). Another aspect worthy of mention here is that many utilitarians since Bentham hold that the moral status of a being comes from its ability to feel pleasure and pain: therefore, moral agents should consider not only the interests of human beings but also those of (other) animals. Richard Ryder came to the same conclusion in his concepts of 'speciesism' and 'painism'. Peter Singer's writings, especially the book Animal Liberation, represent the leading edge of this kind of utilitarianism for animals as well as for people.

Another doctrine related to the relief of suffering is humanitarianism (see also humanitarian principles, humanitarian aid, and humane society). "Where humanitarian efforts seek a positive addition to the happiness of sentient beings, it is to make the unhappy happy rather than the happy happier. ... [Humanitarianism] is an ingredient in many social attitudes; in the modern world it has so penetrated into diverse movements ... that it can hardly be said to exist in itself."Crane Brinton, article Humanitarianism, Encyclopaedia of the Social Sciences, 1937

Pessimists hold this world to be mainly bad, or even the worst possible, plagued with, among other things, unbearable and unstoppable suffering. Some identify suffering as the nature of the world and conclude that it would be better if life did not exist at all. Arthur Schopenhauer recommends us to take refuge in things like art, philosophy, loss of the will to live, and tolerance toward 'fellow-sufferers'.

Friedrich Nietzsche, first influenced by Schopenhauer, developed afterward quite another attitude, arguing that the suffering of life is productive, exalting the will to power, despising weak compassion or pity, and recommending us to embrace willfully the 'eternal return' of the greatest sufferings.

Some philosophers have questioned whether suffering has a genuine positive counterpart. A phenomenological argument presented by Magnus Vinding claims that while positive experiences such as joy or excitement are real, they do not serve as opposites to suffering in either phenomenological or axiological terms.

Philosophy of pain is a philosophical speciality that focuses on physical pain and is, through that, relevant to suffering in general.

Religion Suffering plays an important role in a number of religions, regarding matters such as the following: consolation or relief; moral conduct (do no harm, help the afflicted, show compassion); spiritual advancement through life hardships or through self-imposed trials (mortification of the flesh, penance, asceticism); ultimate destiny (salvation, damnation, hell). Theodicy deals with the problem of evil, which is the difficulty of reconciling the existence of an omnipotent and benevolent god with the existence of evil. "Several attempts were made to preserve together both monotheism and God’s attributes from types of dualism (e. g. Gnosticism, Paulicianism, Catharism) and the idea of God’s reduced number of attributes, due to the tension between the existence of evil and the divine omnipotence and omnibenevolence." A quintessential form of evil, for many people, is extreme suffering, especially in innocent children, or in creatures destined to an eternity of torments (see problem of hell).

The 'Four Noble Truths' of Buddhism are about dukkha, a term often translated as suffering. They state the nature of suffering, its cause, its cessation, and the way leading to its cessation, the Noble Eightfold Path. Buddhism considers liberation from dukkha and the practice of compassion (karuna) as basic for leading a holy life and attaining nirvana.
