Kavka's Toxin Puzzle
Kavka's toxin puzzle is a thought experiment about the possibility of forming an intention to perform an act which, following from reason, is an action one would not actually perform. It was presented by moral and political philosopher Gregory S. Kavka in "The Toxin Puzzle" (1983), and grew out of his work in deterrence theory and mutual assured destruction. The puzzle Kavka's original version of the puzzle is the following: An eccentric billionaire places before you a vial of toxin that, if you drink it, will make you painfully ill for a day, but will not threaten your life or have any lasting effects. The billionaire will pay you one million dollars tomorrow morning if, at midnight tonight, you ''intend'' to drink the toxin tomorrow afternoon. He emphasizes that you need not drink the toxin to receive the money; in fact, the money will already be in your bank account hours before the time for drinking it arrives, if you succeed. All you have to do is ... intend at midnight t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thought Experiment
A thought experiment is an imaginary scenario that is meant to elucidate or test an argument or theory. It is often an experiment that would be hard, impossible, or unethical to actually perform. It can also be an abstract hypothetical that is meant to test our intuitions about morality or other fundamental philosophical questions. History The ancient Greek , "was the most ancient pattern of mathematical proof", and existed before Euclidean geometry, Euclidean mathematics, where the emphasis was on the conceptual, rather than on the experimental part of a thought experiment. Johann Witt-Hansen established that Hans Christian Ørsted was the first to use the equivalent German term . Ørsted was also the first to use the equivalent term in 1820. By 1883, Ernst Mach used in a different sense, to denote exclusively the conduct of a experiment that would be subsequently performed as a by his students. Physical and mental experimentation could then be contrasted: Mach asked hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deterrence Theory
Deterrence theory refers to the scholarship and practice of how threats of using force by one party can convince another party to refrain from initiating some other course of action. The topic gained increased prominence as a military strategy during the Cold War with regard to the use of nuclear weapons and is related to but distinct from the concept of mutual assured destruction, according to which a full-scale nuclear attack on a power with second-strike capability would devastate both parties. The central problem of deterrence revolves around how to credibly threaten military action or nuclear punishment on the adversary despite its costs to the deterrer. Deterrence in an international relations context is the application of deterrence theory to avoid conflict. Deterrence is widely defined as any use of threats (implicit or explicit) or limited force intended to dissuade an actor from taking an action (i.e. maintain the status quo). Deterrence is unlike compellence, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mutual Assured Destruction
Mutual assured destruction (MAD) is a doctrine of military strategy and national security policy which posits that a full-scale use of nuclear weapons by an attacker on a nuclear-armed defender with second-strike capabilities would result in the complete annihilation of both the attacker and the defender. It is based on the theory of rational deterrence, which holds that the threat of using strong weapons against the enemy prevents the enemy's use of those same weapons. The strategy is a form of Nash equilibrium in which, once armed, neither side has any incentive to initiate a conflict or to disarm. The result may be a nuclear peace, in which the presence of nuclear weapons decreases the risk of crisis escalation, since parties will seek to avoid situations that could lead to the use of nuclear weapons. Proponents of nuclear peace theory therefore believe that controlled nuclear proliferation may be beneficial for global stability. Critics argue that nuclear proliferation i ...

Newcomb's Paradox
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 with near-certainty. Newcomb's paradox was created by William Newcomb of the University of California's Lawrence Livermore Laboratory. However, it was first analyzed in a philosophy paper by Robert Nozick in 1969 and appeared in the March 1973 issue of ''Scientific American'', in Martin Gardner's " Mathematical Games". Reprinted with an addendum and annotated bibliography in his book ''The Colossal Book of Mathematics'' (). Today it is a much debated problem in the philosophical branch of decision theory. The problem There are two agents: a reliable predictor and a player. Two boxes are designated A and B. The player is given a choice between taking only box B or taking both boxes A and B. The player knows the following: * Box A is transparent and always contains a visible $1,000. * Box B is opa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Omniscient
Omniscience is the property of possessing maximal knowledge. In Hinduism, Sikhism and the Abrahamic religions, it is often attributed to a divine being or an all-knowing spirit, entity or person. In Jainism, omniscience is an attribute that any individual can eventually attain. In Buddhism, there are differing beliefs about omniscience among different schools. Etymology The word ''omniscience'' derives from the Latin word '' sciens'' ("to know" or "conscious") and the prefix '' omni'' ("all" or "every"), but also means " all-seeing". In religion Buddhism The topic of omniscience has been much debated in various Indian traditions, but no more so than by the Buddhists. After Dharmakirti's excursions into the subject of what constitutes a valid cognition, Śāntarakṣita and his student Kamalaśīla thoroughly investigated the subject in the Tattvasamgraha and its commentary the Panjika. The arguments in the text can be broadly grouped into four sections: * The refutation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free Will
Free will is generally understood as the capacity or ability of people to (a) choice, choose between different possible courses of Action (philosophy), action, (b) exercise control over their actions in a way that is necessary for moral responsibility, or (c) be the ultimate source or originator of their actions. There are different theories as to its nature, and these aspects are often emphasized differently depending on philosophical tradition, with debates focusing on whether and how such freedom can coexist with determinism, divine foreknowledge, and other constraints. Free will is closely linked to the concepts of moral responsibility, praise, culpability, and other judgements which apply only to actions that are freely chosen. It is also connected with the concepts of Advice (opinion), advice, persuasion, deliberation, and Prohibitionism, prohibition. Traditionally, only actions that are freely Will (philosophy), willed are seen as deserving credit or blame. Whether free ...

Retrocausality
Retrocausality, or backwards causation, is a concept of cause and effect in which an effect precedes its cause in time and so a later event affects an earlier one. In quantum physics, the distinction between cause and effect is not made at the most fundamental level and so time-symmetric systems can be viewed as causal or retrocausal. Philosophical considerations of time travel often address the same issues as retrocausality, as do treatments of the subject in fiction, but the two phenomena are distinct. Philosophy Philosophical efforts to understand causality extend back at least to Aristotle's discussions of the four causes. It was long considered that an effect preceding its cause is an inherent self- contradiction because, as 18th century philosopher David Hume discussed, when examining two related events, the cause is by definition the one that precedes the effect. The idea of retrocausality is also found in Indian philosophy. It was defended by at least two Indian Buddhis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Gauthier
David Gauthier (; 10 September 1932 – 9 November 2023) was a Canadian philosopher best known for his neo- Hobbesian or contractarian theory of morality, as developed in his 1986 book ''Morals by Agreement''.

Doublethink
Doublethink is a process of indoctrination in which subjects are expected to simultaneously accept two conflicting beliefs as truth, often at odds with their own memory or sense of reality. Doublethink is related to, but differs from, hypocrisy. George Orwell coined the term '' doublethink'' as part of the fictional language of Newspeak in his 1949 dystopian novel '' Nineteen Eighty-Four''.Orwell, George. 1949. ''Nineteen Eighty-Four''. London: Martin Secker & Warburg Ltd. In the novel, its origins within the citizenry are unclear; while it could be partly a product of Big Brother's formal brainwashing programmes,Such as, for example, the seemingly formal brainwashing programme that broke Winston Smith. the novel explicitly shows people learning doublethink and Newspeak due to peer pressure and a desire to "fit in", or gain status within the Party—to be seen as a loyal Party Member. In the novel, for someone to even recognize—let alone mention—any contradiction within ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prisoner's Dilemma
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_Forbes_Nash_Jr., John Nash remarked that rational behavior in the Prisoner's dilemma#The_iterated_prisoner's_dilemma, iterated version of the game can differ from that in a single-round version. This insight anticipated a Folk_theorem_(game_theory), key result in game theory: cooperation can emerge in repeated interactions, even in situations where it i ...
