Steven Kuhn is a philosophy professor at Georgetown University whose research focuses on logic, ethics and the philosophy of language. [1]
Kuhn earned his undergraduate degree in mathematics from Johns Hopkins University and his Ph.D. from Stanford University. Prior to his position at Georgetown, he taught at the University of Michigan, UCLA and the University of Pennsylvania.
Kuhn is the author of the two-volume Many-sorted Modal Logics (1977) and contributed the article on the prisoner's dilemma to the Stanford Encyclopedia of Philosophy . [2]
Kuhn has written extensively on the prisoner's dilemma. In his article 'Pure and Utilitarian Prisoner's dilemmas', [3] he distinguishes between a 'pure' prisoner's dilemma and an impure prisoner's dilemma. A "pure dilemma" is defined when no mixed strategies improve outcomes over mutual cooperation; it's an "impure dilemma" when such strategies exist. This distinction is interesting since in the case of an "impure dilemma", individuals who do not consistently follow moral rules can gain an advantage over individuals who do. Therefore, the possibility that moral behaviour requires randomization of one's actions arises.
In his subsequent paper "The Impure Game: Feasible Payoffs and Possible Generalizations", Kuhn attempts to extend the concept of impurity to other games, such as the Chicken Game and the Battle of the Sexes .
Kuhn has pointed out two obstacles towards the synthesis between game theory and ethics first suggested by R. B. Braithwaite. Firstly, he argues that there is a lack of careful consideration in choosing the most suitable game theoretic framework and in interpreting the technical tools used in these discussions. Second, he cites some challenging examples from game theory. [4]
Kuhn then points out that even in a pure dilemma, if utilities are transferable (i.e., one can compensate the other), universal cooperation might not be the optimal collective strategy. The scenario with possible utility transfers that benefit both players is termed a "nonutilitarian dilemma," and "utilitarian dilemma" otherwise. These distinctions in the prisoner's dilemma have practical implications, such as in the formulation of moral rules or the structuring of legal contracts, where the type of dilemma can influence recommended or optimal behaviors.
In Pragmatics of Tense, Kuhn argues applies a framework inspired by Montague's to analyze the English tense system, suggesting that shared knowledge impacts the use of tenses, hence the use of the word pragmatics. This principle, Kuhn argues, could also apply to other linguistic elements such as pronouns and ambiguity. [5]
He has 1084 citations and an h-index of 13 on Google Scholar. [6]
Applied ethics is the practical aspect of moral considerations. It is ethics with respect to real-world actions and their moral considerations in private and public life, the professions, health, technology, law, and leadership. For example, bioethics is concerned with identifying the best approach to moral issues in the life sciences, such as euthanasia, the allocation of scarce health resources, or the use of human embryos in research. Environmental ethics is concerned with ecological issues such as the responsibility of government and corporations to clean up pollution. Business ethics includes the duties of whistleblowers to the public and to their employers.
Game theory is the study of mathematical models of strategic interactions. It has applications in many fields of social science, and is used extensively in economics, logic, systems science and computer science. Initially, game theory addressed two-person zero-sum games, in which a participant's gains or losses are exactly balanced by the losses and gains of the other participant. In the 1950s, it was extended to the study of non zero-sum games, and was eventually applied to a wide range of behavioral relations. It is now an umbrella term for the science of rational decision making in humans, animals, and computers.
Normative ethics is the study of ethical behaviour and is the branch of philosophical ethics that investigates questions regarding how one ought to act, in a moral sense.
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 lead to the greatest good for the greatest number. Although different varieties of utilitarianism admit different characterizations, the basic idea behind all of them is, in some sense, to 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 the capacity of actions or objects to produce benefits, such as pleasure, happiness, and good, or to prevent harm, such as pain and unhappiness, to those affected.
The prisoner's dilemma is a game theory thought experiment involving two rational agents, each of whom can either cooperate for mutual benefit or betray their partner ("defect") for individual gain. The dilemma arises from the fact that while defecting is rational for each agent, cooperation yields a higher payoff for each. The puzzle was designed by Merrill Flood and Melvin Dresher in 1950 during their work at the RAND Corporation. They invited economist Armen Alchian and mathematician John Williams to play a hundred rounds of the game, observing that Alchian and Williams often chose to cooperate. When asked about the results, John Nash remarked that rational behavior in the iterated version of the game can differ from that in a single-round version. This insight anticipated a key result in game theory: cooperation can emerge in repeated interactions, even in situations where it is not rational in a one-off interaction.
Relativism is a family of philosophical views which deny claims to objectivity within a particular domain and assert that valuations in that domain are relative to the perspective of an observer or the context in which they are assessed. There are many different forms of relativism, with a great deal of variation in scope and differing degrees of controversy among them. Moral relativism encompasses the differences in moral judgments among people and cultures. Epistemic relativism holds that there are no absolute principles regarding normative belief, justification, or rationality, and that there are only relative ones. Alethic relativism is the doctrine that there are no absolute truths, i.e., that truth is always relative to some particular frame of reference, such as a language or a culture. Some forms of relativism also bear a resemblance to philosophical skepticism. Descriptive relativism seeks to describe the differences among cultures and people without evaluation, while normative relativism evaluates the word truthfulness of views within a given framework.
David Gauthier was a Canadian philosopher best known for his neo-Hobbesian or contractarian theory of morality, as developed in his 1986 book Morals by Agreement.
In philosophy and mathematics, Newcomb's paradox, also known as Newcomb's problem, is a thought experiment involving a game between two players, one of whom is able to predict the future.
Analytic philosophy is an analysis focused, broad, contemporary movement or tradition within Western philosophy, especially anglophone philosophy. Analytic philosophy is characterized by a clarity of prose; rigor in arguments; and making use of formal logic and mathematics, and, to a lesser degree, the natural sciences. It is further characterized by an interest in language and meaning known as the linguistic turn. It has developed several new branches of philosophy and logic, notably philosophy of language, philosophy of mathematics, philosophy of science, modern predicate logic and mathematical logic.
Richard Mervyn Hare, usually cited as R. M. Hare, was a British moral philosopher who held the post of White's Professor of Moral Philosophy at the University of Oxford from 1966 until 1983. He subsequently taught for a number of years at the University of Florida. His meta-ethical theories were influential during the second half of the twentieth century.
In moral philosophy, deontological ethics or deontology is the normative ethical theory that the morality of an action should be based on whether that action itself is right or wrong under a series of rules and principles, rather than based on the consequences of the action. It is sometimes described as duty-, obligation-, or rule-based ethics. Deontological ethics is commonly contrasted to consequentialism, utilitarianism, virtue ethics, and pragmatic ethics. In this terminology, action is more important than the consequences.
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.
In philosophy, an ethical dilemma, also called an ethical paradox or moral dilemma, is a situation in which two or more conflicting moral imperatives, none of which overrides the other, confront an agent. A closely related definition characterizes an ethical dilemma as a situation 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.
Evolutionary ethics is a field of inquiry that explores how evolutionary theory might bear on our understanding of ethics or morality. The range of issues investigated by evolutionary ethics is quite broad. Supporters of evolutionary ethics have argued that it has important implications in the fields of descriptive ethics, normative ethics, and metaethics.
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 ethics of care is a normative ethical theory that holds that moral action centers on interpersonal relationships and care or benevolence as a virtue. EoC is one of a cluster of normative ethical theories that were developed by some feminists and environmentalists since the 1980s. While consequentialist and deontological ethical theories emphasize generalizable standards and impartiality, ethics of care emphasize the importance of response to the individual. The distinction between the general and the individual is reflected in their different moral questions: "what is just?" versus "how to respond?" Carol Gilligan, who is considered the originator of the ethics of care, criticized the application of generalized standards as "morally problematic, since it breeds moral blindness or indifference".
Melvin Dresher was a Polish-born American mathematician, notable for developing, alongside Merrill Flood, the game theoretical model of cooperation and conflict known as the Prisoner's dilemma while at RAND in 1950.
British philosophy refers to the philosophical tradition of the British people. "The native characteristics of British philosophy are these: common sense, dislike of complication, a strong preference for the concrete over the abstract and a certain awkward honesty of method in which an occasional pearl of poetry is embedded".
Pragmatic ethics is a theory of normative philosophical ethics and meta-ethics. Ethical pragmatists such as John Dewey believe that some societies have progressed morally in much the way they have attained progress in science. Scientists can pursue inquiry into the truth of a hypothesis and accept the hypothesis, in the sense that they act as though the hypothesis were true; nonetheless, they think that future generations can advance science, and thus future generations can refine or replace their accepted hypotheses. Similarly, ethical pragmatists think that norms, principles, and moral criteria are likely to be improved as a result of inquiry.
Dutch philosophy is a broad branch of philosophy that discusses the contributions of Dutch philosophers to the discourse of Western philosophy and Renaissance philosophy. The philosophy, as its own entity, arose in the 16th and 17th centuries through the philosophical studies of Desiderius Erasmus and Baruch Spinoza. The adoption of the humanistic perspective by Erasmus, despite his Christian background, and rational but theocentric perspective expounded by Spinoza, supported each of these philosopher's works. In general, the philosophy revolved around acknowledging the reality of human self-determination and rational thought rather than focusing on traditional ideals of fatalism and virtue raised in Christianity. The roots of philosophical frameworks like the mind-body dualism and monism debate can also be traced to Dutch philosophy, which is attributed to 17th century philosopher René Descartes. Descartes was both a mathematician and philosopher during the Dutch Golden Age, despite being from the Kingdom of France. Modern Dutch philosophers like D.H. Th. Vollenhoven provided critical analyses on the dichotomy between dualism and monism.
