The Ramsey test, proposed by Frank Ramsey, suggests evaluating a…The Logic of Conditionals and the Semantics of If-Then StatementsConditional statements—'if P, then Q'—are central to everyday reasoning, but their logic is subtle. Classical logic treats them as material implication, which yields surprising…The Logic of Counterfactual ConditionalsCounterfactual conditionals are 'what-if' statements about situations that did not happen, such as 'If I had studied harder, I would have passed.' Their logic explores how we…The Logic of Counterfactuals and Possible World SemanticsCounterfactuals are 'what-if' statements about alternatives to reality, such as 'If I had studied harder, I would have passed.' Their logic is tricky because truth depends on…The Logic of Counterfactuals and Possible WorldsCounterfactuals are 'what-if' statements about alternatives to reality, such as 'If I had studied, I would have passed.' Possible-worlds semantics, developed by Saul Kripke and…The Logic of Counterfactuals and the Semantics of Subjunctive ConditionalsWe often wonder what would have happened if things had been different.

This card…The Logic of Discovery and Abductive Reasoning in ScienceAbductive reasoning, or inference to the best explanation, is the logic scientists use to generate hypotheses from surprising facts. Unlike deduction, which proves, or…The Logic of Fictional Discourse and Truth in FictionWhen we say 'Sherlock Holmes lived at 221B Baker Street,' we assert something true about a fictional world, even though Holmes never existed. This card explores how fictional…The Logic of Imperative and the Semantics of CommandsImperative sentences like 'Close the door' direct actions rather than describe facts, posing a challenge for standard truth-conditional logic. This card explains how the logic…The Logic of Indexicals and Context-Dependent TruthIndexicals like 'I', 'here', and 'now' shift their reference with the context of utterance, so the same sentence can be true in one context and false in another. This card…The Logic of Indexicals and the Semantics of Context-Dependent TermsIndexicals like 'I', 'here', and 'now' are expressions whose reference shifts with the context of utterance. This card explains how indexicals work, the role of context in…The Logic of Inductive Inference and the Problem of InductionInductive inference draws probable conclusions from observed patterns, such as inferring that all swans are white from seeing only white swans. Unlike deduction, it cannot…The Logic of Inductive Reasoning and the Problem of InductionInductive reasoning draws probable conclusions from observed patterns, as in 'All observed swans are white, so all swans are white.' Unlike deduction, it cannot guarantee…The Logic of Many-Valued Logics and Degrees of TruthClassical logic assumes every proposition is either true or false, but many statements—like 'it is raining' when it's drizzling—seem to fall in between. Many-valued logics…The Logic of Modal Operators and Deontic LogicModal logic extends classical logic by adding operators for necessity and possibility, interpreted through possible worlds. Deontic logic applies this framework to normative…The Logic of Modal Realism and Concrete Possible WorldsThis card explains David Lewis's modal realism, the thesis that possible worlds are concrete, real entities just like our own universe. It explores how this view grounds modal…The Logic of Nonmonotonic Reasoning and Default LogicClassical logic is monotonic: adding premises never removes conclusions. Everyday reasoning, however, is nonmonotonic—new information can defeat previous conclusions. Default…The Logic of Presupposition and Presupposition FailurePresuppositions are background assumptions that must be true for an utterance to be appropriate, not merely true. When they fail, a sentence's truth value becomes undefined or…The Logic of Presupposition and the Semantics of Definite DescriptionsThis card explains how definite descriptions like 'the current king of France' carry presuppositions—assumptions that must hold for a sentence to be true or false. It…The Logic of Presupposition in Semantic and Pragmatic TheoryPresuppositions are implicit assumptions embedded in language that must be true for an utterance to make sense. This card explores how presupposition forms a logical bridge…The Logic of Question-Asking and Erotetic LogicErotetic logic is the formal study of questions, their presuppositions, and what counts as a good answer. It moves beyond classical logic's focus on propositions to treat…The Logic of Questions and Erotetic InferenceErotetic logic studies the structure of questions, their presuppositions, and what makes an answer appropriate. It extends classical logic by treating questions as formal…The Logic of Relevance Logic and the Relevance ConditionRelevance logic is a family of non-classical logics that require a genuine connection—relevance—between premises and conclusions for an argument to be valid. It rejects the…The Logic of Second-Order Logic and Expressive PowerSecond-order logic (SOL) extends first-order logic by allowing quantification over properties and relations, not just objects. This added expressive power lets SOL capture…The Logic of Set Theory and the Paradoxes of Naive ComprehensionSet theory, the mathematical theory of collections, begins with the naive principle that any condition defines a set. This seemingly straightforward idea leads to paradoxes…The Logic of Temporal Reasoning and the Philosophy of TimeTemporal logic formalizes reasoning about time using operators for 'always' and 'eventually', based on a structure of instants and an order relation. It links tense in…The Logic of Vague Predicates and the Sorites ParadoxVague predicates like 'tall' have fuzzy boundaries, and the sorites paradox shows how classical logic collapses when we reason about them step-by-step. This card explains the…The Logic of Vagueness and Many-Valued Truth TheoriesVague predicates like 'tall' or 'heap' have no sharp boundaries, which creates paradoxes when classical logic insists on two truth values. Many-valued logics, such as…The Logic of Vagueness and SupervaluationismVague predicates like 'tall' and 'heap' have no sharp boundaries, challenging classical logic's demand for bivalence. Supervaluationism responds by treating vague statements as…The Logic of Vagueness and the Sorites ParadoxThis card explores how vague predicates like 'tall' or 'heap' create logical paradoxes. It introduces the sorites paradox, where removing one grain from a heap never seems to…The Logic of Validity and the Semantic ParadoxesSemantic paradoxes like the Liar ('This sentence is false') challenge our ordinary notion of validity, revealing that classical logic's definition—truth-preservation from…The Logical Fallacy of Appeal to Authority in Scientific DiscourseThe appeal to authority fallacy occurs when someone relies on an expert's opinion as conclusive proof without examining the underlying evidence. In science, this is dangerous…The Logical Structure of Scientific Explanation: Deduction, Statistics, and MechanismScientific explanations come in distinct logical patterns. Some deduce a fact from general laws, some cite statistical probabilities, and some describe underlying mechanisms.…The Meaning of Life: Absurdism and Existentialist ResponsesThis card explores the philosophical question of life's meaning through the lenses of absurdism and existentialism, focusing on Camus's concept of the absurd and the…The Meaning of Life: Absurdism and Existentialist ResponsesThis card explores the philosophical problem of finding meaning in a seemingly indifferent universe. It introduces absurdism, the conflict between humanity's search for meaning…The Meaning of Life: Absurdism and Existentialist ResponsesThis card explores the philosophical problem of life's meaning when the universe offers no answer. Absurdism, especially Albert Camus's, locates meaning in the collision…The Meaning of Life: Absurdism and Existentialist ResponsesThis card explores the philosophical problem of life's meaning through the lens of absurdism and existentialism. It covers Albert Camus's idea of the absurd, the conflicting…The Mechanisms of Soft Power and Cultural InfluenceSoft power is the ability to shape others' preferences through attraction rather than coercion. This card explains the core mechanisms—culture, political values, and foreign…The Mereological Fallacy: Parts, Wholes, and Mental PredicatesThe mereological fallacy is the error of attributing mental states (like thinking or feeling) to the parts of an organism—such as the brain—when such predicates logically apply…
