Means
Suffering, or pain in a broad sense, is an individual's basic affective experience of unpleasantness and aversion associated with harm or threat of harm. Suffering may be qualified as physical or mental. It may come in all degrees of intensity, from mild to intolerable. Factors of duration and frequency of occurrence usually compound that of intensity. In addition to such factors, people's attitudes toward suffering may take into account how much it is, in their opinion, avoidable or unavoidable, useful or useless, deserved or undeserved.
Suffering occurs commonly in the lives of sentient beings, in diverse manners, and often dramatically. As a result, many fields of human activity are concerned, from their own points of view, 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 mental or emotional pain, or more often yet 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 mental, emotional, psychological, and spiritual, are often used for referring 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 such as itching or nausea. 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.
Unpleasantness is another synonym of suffering or pain in the broad sense. More technically, the term is used in physical pain science for referring to the basic affective dimension of pain (its suffering aspect per se), usually in contrast with the sensory dimension, as for instance in this sentence from Professor Donald Price: “Pain-unpleasantness is often, though not always, closely linked to both the intensity and unique qualities of the painful sensation.” Words that are roughly synonymic with suffering, in addition to pain and unpleasantness, include distress, sorrow, unhappiness, misery, affliction, woe, ill, discomfort, displeasure, disagreeableness.
Philosophy
Hedonism, as an ethical theory, claims that good and bad consist ultimately in pleasure and pain. Many hedonists, in accordance with Epicurus, emphasize avoiding suffering over pursuing pleasure, because they find that the greatest happiness lies in a tranquil state (ataraxia) free from pain and from the worrisome pursuit or unwelcome consequences of pleasure. 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.
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 an 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 developed such a view 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."
Pessimism holds this world to be the worst possible, plagued with worsening and unstoppable suffering. 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, exalting the will to power, despising weak compassion or pity, and recommending us to embrace willfully the 'eternal return' of the greatest sufferings.
Philosophy of pain is a philosophical specialty that focuses on physical pain as a sensation. Through that topic, it may also pertain to suffering in general.
