Summum bonumSummum bonum is a Latin expression meaning the highest or ultimate good, which was introduced by the Roman philosopher Cicero to denote the fundamental principle on which some system of ethics is based — that is, the aim of actions, which, if consistently pursued, will lead to the best possible life. Since Cicero, the expression has acquired a secondary meaning as the essence or ultimate metaphysical principle of Goodness itself, or what Plato called the Form of the Good. These two meanings do not necessarily coincide.
Moral agencyMoral agency is an individual's ability to make moral choices based on some notion of right and wrong and to be held accountable for these actions. A moral agent is "a being who is capable of acting with reference to right and wrong." Most philosophers suggest only rational beings, who can reason and form self-interested judgments, are capable of being moral agents. Some suggest those with limited rationality (for example, people who are mildly mentally disabled or infants) also have some basic moral capabilities.
Original positionThe 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.
Rule utilitarianismRule 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. For rule utilitarians, the correctness of a rule is determined by the amount of good it brings about when followed.
Act utilitarianismAct 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. To understand how act utilitarianism works, compare the consequences of watching television all day tomorrow to the consequences of doing charity work tomorrow.
Preference utilitarianismPreference utilitarianism (also known as preferentialism) is a form of utilitarianism in contemporary philosophy. It is distinct from original utilitarianism in that it values actions that fulfill the most personal interests, as opposed to actions that generate the most pleasure. Unlike classical utilitarianism, in which right actions are defined as those that maximize pleasure and minimize pain, preference utilitarianism entails promoting actions that fulfil the interests (i.e., preferences) of those beings involved.
AristippusAristippus of Cyrene (ˌærəˈstɪpəs; Ἀρίστιππος ὁ Κυρηναῖος; c. 435 – c. 356 BCE) was a hedonistic Greek philosopher and the founder of the Cyrenaic school of philosophy. He was a pupil of Socrates, but adopted a different philosophical outlook, teaching that the goal of life was to seek pleasure by adapting circumstances to oneself and by maintaining proper control over both adversity and prosperity. His view that pleasure is the only good came to be called ethical hedonism.
Ethical dilemmaIn philosophy, ethical dilemmas, also called ethical paradoxes or moral dilemmas, are situations in which an agent stands under two (or more) conflicting moral requirements, none of which overrides the other. A closely related definition characterizes ethical dilemmas as situations in which every available choice is wrong. The term is also used in a wider sense in everyday language to refer to ethical conflicts that may be resolvable, to psychologically difficult choices or to other types of difficult ethical problems.
Demandingness objectionThe demandingness objection is a common argument raised against utilitarianism and other consequentialist ethical theories. The consequentialist requirement that we maximize the good impartially seems to this objection to require us to perform acts that we would normally consider optional. For example, if our resources maximize utility through charitable contributions rather than spending them on ourselves, we are, according to utilitarianism, morally required to do so.
Brad HookerBrad Hooker (born 13 September 1957) is a British-American philosopher who specialises in moral philosophy. He is a professor at the University of Reading and is best known for his work defending rule consequentialism (often treated as being synonymous with rule utilitarianism). His book Ideal Code, Real World received a number of favourable reviews from high-profile philosophers. Derek Parfit, for example, wrote: "This book seems to me the best statement and defence, so far, of one of the most important moral theories.
