Swamping problem

Last updated

The swamping problem is a problem that appears in the context of epistemology that shows that the idea that knowledge has no additional value over true belief. The problem assumes that knowledge is a true justified belief—the canonical definition—and proceeds to show that knowledge has no more value over true belief by showing that the justification requirement does not add value to the definition. The first known historical mentioning of the problem is in Plato's Meno, when Meno and Socrates have a discussion on how they should choose their guide to Larissa. Meno suggests that they need someone who knows the route, but Socrates suggests that someone with true opinion will do as well.

Epistemology A branch of philosophy concerned with the nature and scope of knowledge

Epistemology is the branch of philosophy concerned with the theory of knowledge.

Plato Classical Greek philosopher

Plato was an Athenian philosopher during the Classical period in Ancient Greece and the founder of the Academy, the first institution of higher learning in the Western world. He is widely considered the pivotal figure in the history of Ancient Greek and Western philosophy, along with his teacher, Socrates, and his most famous student, Aristotle. Alfred North Whitehead once noted: "the safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato."

Meno is a Socratic dialogue written by Plato. It appears to attempt to determine the definition of virtue, or arete, meaning virtue in general, rather than particular virtues, such as justice or temperance. The first part of the work is written in the Socratic dialectical style and Meno is reduced to confusion or aporia. In response to Meno's paradox, however, Socrates introduces positive ideas: the immortality of the soul, the theory of knowledge as recollection (anamnesis), which Socrates demonstrates by posing a mathematical puzzle to one of Meno's slaves, the method of hypothesis, and, in the final lines, the distinction between knowledge and true belief.

Foundationalism concerns philosophical theories of knowledge resting upon justified belief, or some secure foundation of certainty such as a conclusion inferred from a basis of sound premises. The main rival of the foundationalist theory of justification is the coherence theory of justification, whereby a body of knowledge, not requiring a secure foundation, can be established by the interlocking strength of its components, like a puzzle solved without prior certainty that each small region was solved correctly.

The theory of justification is a part of epistemology that attempts to understand the justification of propositions and beliefs. Epistemologists are concerned with various epistemic features of belief, which include the ideas of justification, warrant, rationality, and probability. Loosely speaking, justification is the reason that someone (properly) holds a belief.

The regress argument is a problem in epistemology and, in general, a problem in any situation where a statement has to be justified.

Belief Psychological state in which an individual holds a proposition or premise to be true

Belief is the state of mind in which a person thinks something to be the case regardless of empirical evidence to prove that something is the case with factual certainty. Another way of defining belief sees it as a mental representation of an attitude positively oriented towards the likelihood of something being true. In the context of Ancient Greek thought, two related concepts were identified with regards to the concept of belief: pistis and doxa. Simplified, we may say that pistis refers to "trust" and "confidence", while doxa refers to "opinion" and "acceptance". The English word "orthodoxy" derives from doxa. Jonathan Leicester suggests that belief has the purpose of guiding action rather than indicating truth.

Edmund L. Gettier III is an American philosopher and Professor Emeritus at the University of Massachusetts Amherst. He is best known for his short 1963 article "Is Justified True Belief Knowledge?", which has generated an extensive philosophical literature trying to respond to what became known as the Gettier problem.

The Gettier problem, in the field of epistemology, is a landmark philosophical problem concerning our understanding of descriptive knowledge. Attributed to American philosopher Edmund Gettier, Gettier-type counterexamples challenge the long-held justified true belief (JTB) account of knowledge. The JTB account holds that knowledge is equivalent to justified true belief; if all three conditions are met of a given claim, then we have knowledge of that claim. In his 1963 three-page paper titled "Is Justified True Belief Knowledge?", Gettier attempts to illustrate by means of two counterexamples that there are cases where individuals can have a justified, true belief regarding a claim but still fail to know it because the reasons for the belief, while justified, turn out to be false. Thus, Gettier claims to have shown that the JTB account is inadequate; that it does not account for all of the necessary and sufficient conditions for knowledge.

Coherentism is the name given to a few philosophical theories in modern epistemology.

<i>Euthyphro</i> book

Euthyphro, by Plato, is a Socratic dialogue whose events occur in the weeks before the trial of Socrates, between Socrates and Euthyphro. The dialogue covers subjects such as the meaning of piety and justice.

Virtue epistemology is a contemporary philosophical approach to epistemology that stresses the importance of intellectual, and specifically epistemic virtues. A distinguishing factor of virtue theories is that they use for the evaluation of knowledge the properties of the persons who hold beliefs in addition to or instead of the properties of propositions and beliefs. Some advocates of virtue epistemology claim to more closely follow theories of virtue ethics, while others see only a looser analogy between virtue in ethics and virtue in epistemology.

Doxa is a Greek word meaning common belief or popular opinion. Used by the Greek rhetoricians as a tool for the formation of argument by using common opinions, the doxa was often manipulated by sophists to persuade the people, leading to Plato's condemnation of Athenian democracy.

Plato's Problem is the term given by Noam Chomsky to "the problem of explaining how we can know so much" given our limited experience. Chomsky believes that Plato asked how we should account for the rich, intrinsic, common structure of human cognition, when it seems undetermined by extrinsic evidence presented to a person during human development. In linguistics this is referred to as the "argument from poverty of the stimulus" (APS). Such arguments are common in the natural sciences, where a developing theory is always "underdetermined by evidence". Chomsky's approach to Plato's Problem involves treating cognition as a normal research topic in the natural sciences, so cognition can be studied to elucidate intertwined genetic, developmental, and biophysical factors. Plato's Problem is most clearly illustrated in the Meno dialogue, in which Socrates demonstrates that an uneducated boy nevertheless understands geometric principles.

Outline of epistemology

The following outline is provided as an overview of and topical guide to epistemology:

Socratic questioning

Socratic questioning was named after Socrates, who was a philosopher in c. 470 BCE–c. 399 BCE. Socrates utilized an educational method that focused on discovering answers by asking questions from his students. Socrates believed that "the disciplined practice of thoughtful questioning enables the scholar/student to examine ideas and be able to determine the validity of those ideas". Plato, a student of Socrates, described this rigorous method of teaching to explain that the teacher assumes an ignorant mindset in order to compel the student to assume the highest level of knowledge. Thus, a student has the ability to acknowledge contradictions, recreate inaccurate or unfinished ideas and critically determine necessary thought.

Epistemology or theory of knowledge is the branch of philosophy concerned with the nature and scope (limitations) of knowledge. It addresses the questions "What is knowledge?", "How is knowledge acquired?", "What do people know?", "How do we know what we know?", and "Why do we know what we know?". Much of the debate in this field has focused on analyzing the nature of knowledge and how it relates to similar notions such as truth, belief, and justification. It also deals with the means of production of knowledge, as well as skepticism about different knowledge claims.

Menos slave

Meno's slave is a character in the Socratic dialogue Meno, which was written by Plato.

In philosophy, anamnesis is a concept in Plato's epistemological and psychological theory that he develops in his dialogues Meno and Phaedo, and alludes to in his Phaedrus.
