context_page_description: Utilitarianism is a family of normative ethical theories that promotes actions that maximize happiness and well-being for all affected individuals. Although different varieties of utilitarianism admit different characterizations, the basic idea behind all of them is to in some sense maximize utility, which is often defined in terms of well-being or related concepts. For instance, Jeremy Bentham, the founder of utilitarianism, described utility as "that property in any object, whereby it tends to produce benefit, advantage, pleasure, good, or happiness...[or] to prevent the happening of mischief, pain, evil, or unhappiness to the party whose interest is considered."
  Utilitarianism is a version of consequentialism, which states that the consequences of any action are the only standard of right and wrong. Unlike other forms of consequentialism, such as egoism and altruism, utilitarianism considers the interests of all humans equally. Proponents of utilitarianism have disagreed on a number of points, such as whether actions should be chosen based on their likely results, or whether agents should conform to rules that maximize utility.
context_section_description: In An Introduction to the Principles of Morals and Legislation Bentham wrote "the question is not, Can they reason? nor, Can they talk? but, Can they suffer?" Mill's distinction between higher and lower pleasures might suggest that he gave more status to humans. However, in his essay "Whewell on Moral Philosophy", Mill defends Bentham's position, calling it a 'noble anticipation', and writing: "Granted that any practice causes more pain to animals than it gives pleasure to man; is that practice moral or immoral? And if, exactly in proportion as human beings raise their heads out of the slough of selfishness, they do not with one voice answer 'immoral', let the morality of the principle of utility be for ever condemned."
  Henry Sidgwick also considers the implications of utilitarianism for nonhuman animals. He writes: "We have next to consider who the 'all' are, whose happiness is to be taken into account. Are we to extend our concern to all the beings capable of pleasure and pain whose feelings are affected by our conduct? or are we to confine our view to human happiness? The former view is the one adopted by Bentham and Mill, and (I believe) by the Utilitarian school generally: and is obviously most in accordance with the universality that is characteristic of their principle ... it seems arbitrary and unreasonable to exclude from the end, as so conceived, any pleasure of any sentient being."
  Among contemporary utilitarian philosophers, Peter Singer is especially known for arguing that the well-being of all sentient beings ought to be given equal consideration. Singer suggests that rights are conferred according to the level of a creature's self-awareness, regardless of their species. He adds that humans tend to be speciesist (discriminatory against non-humans) in ethical matters, and argues that, on utilitarianism, speciesism cannot be justified as there is no rational distinction that can be made between the suffering of humans and the suffering of nonhuman animals; all suffering ought to be reduced. Singer writes: "The racist violates the principle of equality by giving greater weight to the interests of members of his own race, when there is a clash between their interests and the interests of those of another race. Similarly the speciesist allows the interests of his own species to override the greater interests of members of other species. The pattern is the same in each case ... Most human beings are speciesists."
  In his 1990 edition of Animal Liberation, Peter Singer said that he no longer ate oysters and mussels, because although the creatures might not suffer, there was a possibility they may and it was easy to avoid eating them in any case.
  This view still might be contrasted with deep ecology, which holds that an intrinsic value is attached to all forms of life and nature, whether currently assumed to be sentient or not. According to utilitarianism, the forms of life that are unable to experience anything akin to either enjoyment or discomfort are denied moral status, because it is impossible to increase the happiness or reduce the suffering of something that cannot feel happiness or suffer. Singer writes:
  The capacity for suffering and enjoying things is a prerequisite for having interests at all, a condition that must be satisfied before we can speak of interests in any meaningful way. It would be nonsense to say that it was not in the interests of a stone to be kicked along the road by a schoolboy. A stone does not have interests because it cannot suffer. Nothing that we can do to it could possibly make any difference to its welfare. A mouse, on the other hand, does have an interest in not being tormented, because it will suffer if it is. If a being suffers, there can be no moral justification for refusing to take that suffering into consideration. No matter what the nature of the being, the principle of equality requires that its suffering be counted equally with the like suffering—in so far as rough comparisons can be made—of any other being. If a being is not capable of suffering, or of experiencing enj
