In ethical philosophy, consequentialism is a class of normative, teleological ethical theories that holds that the consequences of one's conduct are the ultimate basis for judgement about the rightness or wrongness of that conduct. Thus, from a consequentialist standpoint, a morally right act is one that will produce a good outcome. Consequentialism, along with eudaimonism, falls under the broader category of teleological ethics, a group of views which claim that the moral value of any act consists in its tendency to produce things of intrinsic value. Consequentialists hold in general that an act is right if and only if the act will produce, will probably produce, or is intended to produce, a greater balance of good over evil than any available alternative. Different consequentialist theories differ in how they define moral goods, with chief candidates including pleasure, the absence of pain, the satisfaction of one's preferences, and broader notions of the "general good".
Hedonism refers to the prioritization of pleasure in one's lifestyle, actions, or thoughts. The term can include a number of theories or practices across philosophy, art, and psychology, encompassing both sensory pleasure and more intellectual or personal pursuits, but can also be used in everyday parlance as a pejorative for the egoistic pursuit of short-term gratification at the expense of others.
Robert Nozick was an American philosopher. He held the Joseph Pellegrino University Professorship at Harvard University, and was president of the American Philosophical Association. He is best known for his books Anarchy, State, and Utopia (1974), a libertarian answer to John Rawls' A Theory of Justice (1971), in which Nozick also presented his own theory of utopia as one in which people can freely choose the rules of the society they enter into, and Philosophical Explanations (1981), which included his counterfactual theory of knowledge. His other work involved ethics, decision theory, philosophy of mind, metaphysics and epistemology. His final work before his death, Invariances (2001), introduced his theory of evolutionary cosmology, by which he argues invariances, and hence objectivity itself, emerged through evolution across possible worlds.
In ethical philosophy, utilitarianism is a family of normative ethical theories that prescribe actions that maximize happiness and well-being for the affected individuals. In other words, utilitarian ideas encourage actions that ensure the greatest good for the greatest number.
Derek Antony Parfit was a British philosopher who specialised in personal identity, rationality, and ethics. He is widely considered one of the most important and influential moral philosophers of the late 20th and early 21st centuries.
The original position (OP), often referred to as the veil of ignorance, is a thought experiment used for reasoning about the principles that should structure a society based on mutual dependence. The phrases original position and veil of ignorance were coined by the American philosopher John Rawls, but the thought experiment itself was developed by William Vickrey and John Harsanyi in earlier writings.
In ethics, welfarism is a theory that well-being, what is good for someone or what makes a life worth living, is the only thing that has intrinsic value. In its most general sense, it can be defined as descriptive theory about what has value, but some philosophers also understand welfarism as a moral theory, that what one should do is ultimately determined by considerations of well-being. The right action, policy or rule is the one leading to the maximal amount of well-being. In this sense, it is often seen as a type of consequentialism, and can take the form of utilitarianism.
Reasons and Persons is a 1984 book by the philosopher Derek Parfit, in which the author discusses ethics, rationality and personal identity.
The mere addition paradox is a problem in ethics identified by Derek Parfit and discussed in his book Reasons and Persons (1984). The paradox identifies the mutual incompatibility of four intuitively compelling assertions about the relative value of populations. Parfit’s original formulation of the repugnant conclusion is that “For any perfectly equal population with very high positive welfare, there is a population with very low positive welfare which is better, other things being equal.”
Rule utilitarianism is a form of utilitarianism that says an action is right as it conforms to a rule that leads to the greatest good, or that "the rightness or wrongness of a particular action is a function of the correctness of the rule of which it is an instance". Philosophers Richard Brandt and Brad Hooker are major proponents of such an approach.
The experience machine or pleasure machine is a thought experiment put forward by philosopher Robert Nozick in his 1974 book Anarchy, State, and Utopia. It is an attempt to refute ethical hedonism by imagining a choice between everyday reality and an apparently preferable simulated reality.
Act utilitarianism is a utilitarian theory of ethics that states that a person's act is morally right if and only if it produces the best possible results in that specific situation. Classical utilitarians, including Jeremy Bentham, John Stuart Mill, and Henry Sidgwick, define happiness as pleasure and the absence of pain.
Average and total utilitarianism are variants of utilitarianism that seek to maximize the average or total amount of utility; following Henry Sidgwick's question, "Is it total or average happiness that we seek to make a maximum?". They are theories of population ethics, a philosophical field that deals with problems arising when our actions affect the number or identity of individuals born in the future.
Population ethics is the philosophical study of the ethical problems arising when our actions affect who is born and how many people are born in the future. An important area within population ethics is population axiology, which is "the study of the conditions under which one state of affairs is better than another, when the states of affairs in question may differ over the numbers and the identities of the persons who ever live."
Prioritarianism, or the priority view, is a perspective within ethics and political philosophy stating that "social welfare orderings should give explicit priority to the worse off". Prioritarianism resembles utilitarianism, and is likewise a form of aggregative consequentialism.
The philosophy of happiness is the philosophical concern with the existence, nature, and attainment of happiness. Some philosophers believe happiness can be understood as the moral goal of life or as an aspect of chance; indeed, in most European languages the term happiness is synonymous with luck. Thus, philosophers usually explicate on happiness as either a state of mind, or a life that goes well for the person leading it. Given the pragmatic concern for the attainment of happiness, research in psychology has guided many modern day philosophers in developing their theories.
Negative utilitarianism is a form of negative consequentialism that can be described as the view that people should minimize the total amount of aggregate suffering, or that they should minimize suffering and then, secondarily, maximize the total amount of happiness. It can be considered as a version of utilitarianism that gives greater priority to reducing suffering than to increasing pleasure. This differs from classical utilitarianism, which does not claim that reducing suffering is intrinsically more important than increasing happiness. Both versions of utilitarianism hold that morally right and morally wrong actions depend solely on the consequences for overall aggregate well-being. "Well-being" refers to the state of the individual.
Negative consequentialism is a version of consequentialism, which is "one of the major theories of normative ethics." Like other versions of consequentialism, negative consequentialism holds that moral right and wrong depend only on the value of outcomes. That is, for negative and other versions of consequentialism, questions such as "what should I do?" and "what kind of person should I be?" are answered only based on consequences. Negative consequentialism differs from other versions of consequentialism by giving greater weight in moral deliberations to what is bad than what is good. Due to this, it can be considered an instance of what has been called "suffering-focused ethics", the view that the reduction of suffering has moral priority over any other possible duties we may think of.
The Asymmetry, also known as 'the Procreation Asymmetry', is the idea in population ethics that there is a moral or evaluative asymmetry between bringing into existence individuals with good or bad lives. It was first discussed by Jan Narveson in 1967, and Jeff McMahan coined the term 'the Asymmetry' in 1981. McMahan formulates the Asymmetry as follows: "while the fact that a person's life would be worse than no life at all ... constitutes a strong moral reason for not bringing him into existence, the fact that a person's life would be worth living provides no moral reason for bringing him into existence." Professor Nils Holtug formulates the Asymmetry evaluatively in terms of the value of outcomes instead of in terms of moral reasons. Holtug's formulation says that "while it detracts from the value of an outcome to add individuals whose lives are of overall negative value, it does not increase the value of an outcome to add individuals whose lives are of overall positive value."
The replaceability argument, or the logic of the larder, is a philosophical argument that has been used to reject vegetarianism. It holds that consuming nonhuman animal products is good for animals because if they were not consumed, fewer animals would be brought into existence. The argument has particularly been engaged with within the context of utilitarianism.
