Action guidance One important characteristic of many
normative moral theories such as consequentialism is the ability to produce practical moral judgements. At the very least, any moral theory needs to define the standpoint from which the goodness of the consequences are to be determined. What is primarily at stake here is the
responsibility of the agent.
The ideal observer One common tactic among consequentialists, particularly those committed to an
altruistic (selfless) account of consequentialism, is to employ an ideal, neutral observer from which moral judgements can be made.
John Rawls, a critic of utilitarianism, argues that utilitarianism, in common with other forms of consequentialism, relies on the perspective of such an
ideal observer. However, if this approach is naïvely adopted, then moral agents who, for example, recklessly fail to reflect on their situation, and act in a way that brings about terrible results, could be said to be acting in a morally justifiable way. Acting in a situation without first informing oneself of the circumstances of the situation can lead to even the most well-intended actions yielding miserable consequences. As a result, it could be argued that there is a moral imperative for agents to inform themselves as much as possible about a situation before judging the appropriate course of action. This imperative, of course, is derived from consequential thinking: a better-informed agent is able to bring about better consequences.
Acts and omissions Since pure consequentialism holds that an action is to be judged solely by its result, most consequentialist theories hold that a deliberate action is no different from a deliberate decision not to act. This contrasts with the "
acts and omissions doctrine", which is upheld by some medical ethicists and some religions: it asserts there is a significant moral distinction between acts and deliberate non-actions which lead to the same outcome. This contrast is brought out in issues such as
voluntary euthanasia.
Actualism and possibilism The normative status of an action depends on its consequences according to consequentialism. The consequences of the actions of an agent may include other actions by this agent.
Actualism and possibilism disagree on how later possible actions impact the normative status of the current action by the same agent. Actualists assert that it is only relevant what the agent
would actually do later for assessing the value of an alternative. Possibilists, on the other hand, hold that we should also take into account what the agent
could do, even if she would not do it. For example, assume that Gifre has the choice between two alternatives, eating a cookie or not eating anything. Having eaten the first cookie, Gifre could stop eating cookies, which is the best alternative. But after having tasted one cookie, Gifre would freely decide to continue eating cookies until the whole bag is finished, which would result in a terrible stomach ache and would be the worst alternative. Not eating any cookies at all, on the other hand, would be the second-best alternative. Now the question is: should Gifre eat the first cookie or not? Actualists are only concerned with the actual consequences. According to them, Gifre should not eat any cookies at all since it is better than the alternative leading to a stomach ache. Possibilists, however, contend that the best possible course of action involves eating the first cookie and this is therefore what Gifre should do. One counterintuitive consequence of actualism is that agents can avoid moral obligations simply by having an imperfect
moral character. Douglas W. Portmore has suggested that these and other problems of actualism and possibilism can be avoided by constraining what counts as a genuine alternative for the agent. On his view, it is a requirement that the agent has rational control over the event in question. For example, eating only one cookie and stopping afterward only is an option for Gifre if she has the rational capacity to repress her temptation to continue eating. If the temptation is irrepressible then this course of action is not considered to be an option and is therefore not relevant when assessing what the best alternative is. Portmore suggests that, given this adjustment, we should prefer a view very closely associated with
possibilism called
maximalism. These two approaches could be reconciled by acknowledging the tension between an agent's interests as an individual and as a member of various groups, and seeking to somehow optimize among all of these interests. For example, it may be meaningful to speak of an action as being good for someone as an individual, but bad for them as a citizen of their town.
Non-humans Many consequentialist theories may seem primarily concerned with human beings and their relationships with other human beings. However, some philosophers argue that we should not limit our ethical consideration to the interests of human beings alone.
Jeremy Bentham, who is regarded as the founder of
utilitarianism, argues that animals can experience pleasure and pain, thus demanding that 'non-human animals' should be a serious object of moral concern. More recently,
Peter Singer has argued that it is unreasonable that we do not give equal consideration to the interests of animals as to those of human beings when we choose the way we are to treat them. Such equal consideration does not necessarily imply identical treatment of humans and non-humans, any more than it necessarily implies identical treatment of all humans.
Value of consequences One way to divide various consequentialisms is by the types of consequences that are taken to matter most, that is, which consequences count as good states of affairs. According to
utilitarianism, a good action is one that results in an increase in
pleasure, and the best action is one that results in the most pleasure for the greatest number. Closely related is
eudaimonic consequentialism, according to which a full, flourishing life, which may or may not be the same as enjoying a great deal of pleasure, is the ultimate aim. Similarly, one might adopt an aesthetic consequentialism, in which the ultimate aim is to produce beauty. However, one might fix on non-psychological goods as the relevant effect. Thus, one might pursue an increase in
material equality or
political liberty instead of something like the more ephemeral "pleasure". Other theories adopt a package of several goods, all to be promoted equally. As the consequentialist approach contains an inherent assumption that the outcomes of a moral decision can be quantified in terms of "goodness" or "badness," or at least put
in order of increasing preference, it is an especially suited moral theory for a
probabilistic and
decision theoretical approach. ==Criticisms==
