Richard Ladd Kirkham (born June 18, 1955) is an American philosopher. Among his published works are Theories of Truth (his most-cited work, published by MIT Press in 1992), [1] "Does the Gettier Problem Rest on a Mistake?" Mind (1984. Vol. 93, No. 372), [2] and "On Paradoxes and a Surprise Exam" Philosophia (1991). [3]
Kirkham graduated from Cornell College in 1977 and received his Ph.D. from the University of Notre Dame in 1983.
Kirkham is probably best known for his work on analytic theories of truth. His 1992 book, Theories of Truth: A Critical Introduction, was received positively upon release. [4] In the book, Kirkham proposes that the various theories of truth proposed through the centuries are really not all in competition with one another after all, because they are often intended to answer distinct questions about truth. For example, some have been intended only to provide the extensional necessary and sufficient conditions for truth, while others have been intended to provide a definition of truth, and still others are intended only to explain the linguistic and non-linguistic purposes of statements that predicate truth or falsity. According to MIT Press, this book is their all-time best-selling work in analytic philosophy and nearly half of all English-reading professional philosophers in the world own a personal copy of the book. It has been used as a text in graduate seminars on every inhabited continent and translated into Portuguese and Russian.
He is also the author of four articles in the Routledge Encyclopedia of Philosophy (Routledge, 1998).
Epistemology is the branch of philosophy concerned with knowledge. Epistemologists study the nature, origin, and scope of knowledge, epistemic justification, the rationality of belief, and various related issues. Debates in contemporary epistemology are generally clustered around four core areas:
In philosophy and logic, the classical liar paradox or liar's paradox or antinomy of the liar is the statement of a liar that they are lying: for instance, declaring that "I am lying". If the liar is indeed lying, then the liar is telling the truth, which means the liar just lied. In "this sentence is a lie" the paradox is strengthened in order to make it amenable to more rigorous logical analysis. It is still generally called the "liar paradox" although abstraction is made precisely from the liar making the statement. Trying to assign to this statement, the strengthened liar, a classical binary truth value leads to a contradiction.
Logical positivism, later called logical empiricism, and both of which together are also known as neopositivism, is a movement whose central thesis is the verification principle. This theory of knowledge asserts that only statements verifiable through direct observation or logical proof are meaningful in terms of conveying truth value, information or factual content. Starting in the late 1920s, groups of philosophers, scientists, and mathematicians formed the Berlin Circle and the Vienna Circle, which, in these two cities, would propound the ideas of logical positivism.
Truth or verity is the property of being in accord with fact or reality. In everyday language, truth is typically ascribed to things that aim to represent reality or otherwise correspond to it, such as beliefs, propositions, and declarative sentences.
Willard Van Orman Quine was an American philosopher and logician in the analytic tradition, recognized as "one of the most influential philosophers of the twentieth century". He served as the Edgar Pierce Chair of Philosophy at Harvard University from 1956 to 1978.
Friedrich Ludwig Gottlob Frege was a German philosopher, logician, and mathematician. He was a mathematics professor at the University of Jena, and is understood by many to be the father of analytic philosophy, concentrating on the philosophy of language, logic, and mathematics. Though he was largely ignored during his lifetime, Giuseppe Peano (1858–1932), Bertrand Russell (1872–1970), and, to some extent, Ludwig Wittgenstein (1889–1951) introduced his work to later generations of philosophers. Frege is widely considered to be the greatest logician since Aristotle, and one of the most profound philosophers of mathematics ever.
Analytic philosophy is a broad, contemporary movement or tradition within Western philosophy and especially anglophone philosophy focused on analysis.
In analytic philosophy, a fundamental distinction is made between the use of a term and the mere mention of it. Many philosophical works have been "vitiated by a failure to distinguish use and mention". The distinction can sometimes be pedantic, especially in simple cases where it is obvious.
Richard McKay Rorty was an American philosopher. Educated at the University of Chicago and Yale University, he had strong interests and training in both the history of philosophy and in contemporary analytic philosophy. Rorty's academic career included appointments as the Stuart Professor of Philosophy at Princeton University, Kenan Professor of Humanities at the University of Virginia, and Professor of Comparative literature at Stanford University. Among his most influential books are Philosophy and the Mirror of Nature (1979), Consequences of Pragmatism (1982), and Contingency, Irony, and Solidarity (1989).
Sir Peter Frederick Strawson was an English philosopher. He was the Waynflete Professor of Metaphysical Philosophy at the University of Oxford from 1968 to 1987. Before that, he was appointed as a college lecturer at University College, Oxford, in 1947, and became a tutorial fellow the following year, until 1968. On his retirement in 1987, he returned to the college and continued working there until shortly before his death.
The Gettier problem, in the field of epistemology, is a landmark philosophical problem concerning the 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 because it does not account for all of the necessary and sufficient conditions for knowledge.
In metaphysics and philosophy of language, the correspondence theory of truth states that the truth or falsity of a statement is determined only by how it relates to the world and whether it accurately describes that world.
A consensus theory of truth is the process of taking statements to be true simply because people generally agree upon them.
Neopragmatism, sometimes called post-Deweyan pragmatism, linguistic pragmatism, or analytic pragmatism, is the philosophical tradition that infers that the meaning of words is a result of how they are used, rather than the objects they represent.
Richard Milton Martin was an American logician and analytic philosopher.
Originally, fallibilism is the philosophical principle that propositions can be accepted even though they cannot be conclusively proven or justified, or that neither knowledge nor belief is certain. The term was coined in the late nineteenth century by the American philosopher Charles Sanders Peirce, as a response to foundationalism. Theorists, following Austrian-British philosopher Karl Popper, may also refer to fallibilism as the notion that knowledge might turn out to be false. Furthermore, fallibilism is said to imply corrigibilism, the principle that propositions are open to revision. Fallibilism is often juxtaposed with infallibilism.
The analytic–synthetic distinction is a semantic distinction used primarily in philosophy to distinguish between propositions that are of two types: analytic propositions and synthetic propositions. Analytic propositions are true or not true solely by virtue of their meaning, whereas synthetic propositions' truth, if any, derives from how their meaning relates to the world.
In analytic philosophy, philosophy of language investigates the nature of language and the relations between language, language users, and the world. Investigations may include inquiry into the nature of meaning, intentionality, reference, the constitution of sentences, concepts, learning, and thought.
Aesthetic Theory is a book by the German philosopher Theodor Adorno, which was culled from drafts written between 1956 and 1969 and ultimately published posthumously in 1970. Although anchored by the philosophical study of art, the book is interdisciplinary and incorporates elements of political philosophy, sociology, metaphysics and other philosophical pursuits in keeping with Adorno's boundary-shunning methodology.
Definitions of knowledge try to determine the essential features of knowledge. Closely related terms are conception of knowledge, theory of knowledge, and analysis of knowledge. Some general features of knowledge are widely accepted among philosophers, for example, that it constitutes a cognitive success or an epistemic contact with reality and that propositional knowledge involves true belief. Most definitions of knowledge in analytic philosophy focus on propositional knowledge or knowledge-that, as in knowing that Dave is at home, in contrast to knowledge-how (know-how) expressing practical competence. However, despite the intense study of knowledge in epistemology, the disagreements about its precise nature are still both numerous and deep. Some of those disagreements arise from the fact that different theorists have different goals in mind: some try to provide a practically useful definition by delineating its most salient feature or features, while others aim at a theoretically precise definition of its necessary and sufficient conditions. Further disputes are caused by methodological differences: some theorists start from abstract and general intuitions or hypotheses, others from concrete and specific cases, and still others from linguistic usage. Additional disagreements arise concerning the standards of knowledge: whether knowledge is something rare that demands very high standards, like infallibility, or whether it is something common that requires only the possession of some evidence.
