Unsolved Problems In Philosophy
This is a list of some of the major problems in philosophy. Metaphilosophy Philosophical progress A prominent question in metaphilosophy is that of whether or not philosophical progress occurs and more so, whether such progress in philosophy is even possible. It has even been disputed, most notably by Ludwig Wittgenstein, whether genuine philosophical problems actually exist. The opposite has also been claimed, for example by Karl Popper, who held that such problems do exist, that they are solvable, and that he had actually found definite solutions to some of them. David Chalmers divides inquiry into philosophical progress in metaphilosophy into three questions. # The Existence Question: is there progress in philosophy? # The Comparison Question: is there as much progress in philosophy as in science? # The Explanation Question: why isn't there more progress in philosophy? Philosophy of language Counterfactuals A counterfactual statement is a conditional statement with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edmund Gettier
Edmund Lee Gettier III (; October 31, 1927 – March 23, 2021) was an American philosopher 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. Life Edmund Lee Gettier III was born on October 31, 1927, in Baltimore, Maryland. Gettier obtained his B.A. from Johns Hopkins University in 1949. He earned his PhD in philosophy from Cornell University in 1961 with a dissertation on “Bertrand Russell’s Theories of Belief” written under the supervision of Norman Malcolm. Gettier taught philosophy at Wayne State University from 1957 until 1967 initially as an Instructor, then as an assistant professor, and, latterly, as an associate professor. His philosophical colleagues at Wayne State included, amongst others, Alvin Plantinga and Héctor-Neri Castaneda. In the academic year of 1964–6 ...

Philosophy Of Mind
Philosophy of mind is a branch of philosophy that studies the ontology and nature of the mind and its relationship with the body. The mind–body problem is a paradigmatic issue in philosophy of mind, although a number of other issues are addressed, such as the hard problem of consciousness and the nature of particular mental states.Siegel, S.: ''The Contents of Visual Experience''. New York: Oxford University Press. 2010.Macpherson, F. & Haddock, A., editors, ''Disjunctivism: Perception, Action, Knowledge'', Oxford: Oxford University Press, 2008. Aspects of the mind that are studied include mental events, mental functions, mental property, mental properties, consciousness and neural correlates of consciousness, its neural correlates, the ontology of the mind, the nature of cognition and of thought, and the relationship of the mind to the body. Dualism (philosophy of mind), Dualism and monism are the two central schools of thought on the mind–body problem, although nuanced vie ...

Epistemology
Epistemology (; ), or the theory of knowledge, is the branch of philosophy concerned with knowledge. Epistemology is considered a major subfield of philosophy, along with other major subfields such as ethics, logic, and metaphysics. Epistemologists study the nature, origin, and scope of knowledge, epistemic justification, the rationality of belief, and various related issues. Debates in epistemology are generally clustered around four core areas: # The philosophical analysis of the nature of knowledge and the conditions required for a belief to constitute knowledge, such as truth and justification # Potential sources of knowledge and justified belief, such as perception, reason, memory, and testimony # The structure of a body of knowledge or justified belief, including whether all justified beliefs must be derived from justified foundational beliefs or whether justification requires only a coherent set of beliefs # Philosophical skepticism, which questions the possibili ...

Globe
A globe is a spherical model of Earth, of some other celestial body, or of the celestial sphere. Globes serve purposes similar to maps, but unlike maps, they do not distort the surface that they portray except to scale it down. A model globe of Earth is called a terrestrial globe. A model globe of the celestial sphere is called a ''celestial globe''. A globe shows details of its subject. A terrestrial globe shows landmasses and water bodies. It might show nations and major cities and the network of latitude and longitude lines. Some have raised relief to show mountains and other large landforms. A celestial globe shows notable stars, and may also show positions of other prominent astronomical objects. Typically, it will also divide the celestial sphere into constellations. The word ''globe'' comes from the Latin word ''globus'', meaning "sphere". Globes have a long history. The first known mention of a globe is from Strabo, describing the Globe of Crates from about 150&nb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cube
In geometry, a cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. Viewed from a corner it is a hexagon and its net is usually depicted as a cross. The cube is the only regular hexahedron and is one of the five Platonic solids. It has 6 faces, 12 edges, and 8 vertices. The cube is also a square parallelepiped, an equilateral cuboid and a right rhombohedron a 3-zonohedron. It is a regular square prism in three orientations, and a trigonal trapezohedron in four orientations. The cube is dual to the octahedron. It has cubical or octahedral symmetry. The cube is the only convex polyhedron whose faces are all squares. Orthogonal projections The ''cube'' has four special orthogonal projections, centered, on a vertex, edges, face and normal to its vertex figure. The first and third correspond to the A2 and B2 Coxeter planes. Spherical tiling The cube can also be represented as a spherical tiling, and ...

John Locke
John Locke (; 29 August 1632 – 28 October 1704) was an English philosopher and physician, widely regarded as one of the most influential of Age of Enlightenment, Enlightenment thinkers and commonly known as the "father of liberalism". Considered one of the first of the British Empiricism, empiricists, following the tradition of Francis Bacon, Locke is equally important to social contract theory. His work greatly affected the development of epistemology and political philosophy. His writings influenced Voltaire and Jean-Jacques Rousseau, and many Scottish Enlightenment thinkers, as well as the American Revolutionaries. His contributions to classical republicanism and liberal theory are reflected in the United States Declaration of Independence. Internationally, Locke’s political-legal principles continue to have a profound influence on the theory and practice of limited representative government and the protection of basic rights and freedoms under the rule of law. ...

William Molyneux
William Molyneux FRS (; 17 April 1656 – 11 October 1698) was an Irish writer on science, politics and natural philosophy. He is noted as a close friend of fellow philosopher John Locke, and for proposing Molyneux's Problem, a thought experiment widely discussed. Life He was born in Dublin to Samuel Molyneux (1616–1693), lawyer, landowner and Master Gunner for Ireland, (whose grandfather, Sir Thomas Molyneux, had come to Dublin from Calais in the 1560s), and his wife, Anne, née Dowdall. The second of five children, William Molyneux came from a relatively prosperous Anglican background, with his father established at Castle Dillon in County Armagh, and his uncle Colonel Adam Molyneux holding large estates inherited from the Dowdall's in Ballymulvey, near Ballymahon in County Longford. He was close to his brother Sir Thomas Molyneux, with whom he later shared philosophical interests. His sister Jane married Anthony Dopping, the eventual Anglican Bishop of Meath. In 1671 M ...

Infinite Regress
An infinite regress is an infinite series of entities governed by a recursive principle that determines how each entity in the series depends on or is produced by its predecessor. In the epistemic regress, for example, a belief is justified because it is based on another belief that is justified. But this other belief is itself in need of one more justified belief for itself to be justified and so on. An infinite regress argument is an argument against a theory based on the fact that this theory leads to an infinite regress. For such an argument to be successful, it has to demonstrate not just that the theory in question entails an infinite regress but also that this regress is ''vicious''. There are different ways in which a regress can be vicious. The most serious form of viciousness involves a contradiction in the form of ''metaphysical impossibility''. Other forms occur when the infinite regress is responsible for the theory in question being implausible or for its failure to ...

Foundherentism
In epistemology, foundherentism is a theory of justification that combines elements from the two rival theories addressing infinite regress, foundationalism prone to arbitrariness, and coherentism prone to circularity (problems raised by the Münchhausen trilemma). Overview Foundherentism was developed and defended by Susan Haack in ''Evidence and Inquiry: Towards Reconstruction in Epistemology'' (1993). In principle, foundationalism holds that basic beliefs unilaterally support derived beliefs, with support always directed from the former to the latter; coherentism holds that beliefs mutually support each other when they belong to the same coherent belief-set. As these theories were refined, however, some foundationalists began to admit that even basic beliefs could be fallible, and that derived beliefs could mutually support each other; whereas some coherentists began to admit that experiential beliefs should be weighted so as to reflect realistic degrees of coherence or justifi ...

Coherentist
In philosophical epistemology, there are two types of coherentism: the coherence theory of truth; and the coherence theory of justification (also known as epistemic coherentism). Coherent truth is divided between an anthropological approach, which applies only to localized networks ('true within a given sample of a population, given our understanding of the population'), and an approach that is judged on the basis of universals, such as categorical sets. The anthropological approach belongs more properly to the correspondence theory of truth, while the universal theories are a small development within analytic philosophy. The coherentist theory of justification, which may be interpreted as relating to either theory of coherent truth, characterizes epistemic justification as a property of a belief only if that belief is a member of a coherent set. What distinguishes coherentism from other theories of justification is that the set is the primary bearer of justification. As an epist ...
