Is–ought Problem
The is–ought problem, as articulated by the Scottish philosopher and historian David Hume, arises when one makes claims about what ''ought'' to be that are based solely on statements about what ''is''. Hume found that there seems to be a significant difference between descriptive or positive statements (about what is) and prescriptive or normative statements (about what ought to be), and that it is not obvious how one can coherently move from descriptive statements to prescriptive ones. Hume's law or Hume's guillotine is the thesis that, if a reasoner only has access to non-moral and non-evaluative factual premises, the reasoner cannot logically infer the truth of moral statements.Cohon, Rachel, "Hume's Moral Philosophy", The Stanford Encyclopedia of Philosophy (Fall 2018 Edition), Edward N.

David Hume
David Hume (; born David Home; 7 May 1711 NS (26 April 1711 OS) – 25 August 1776) Cranston, Maurice, and Thomas Edmund Jessop. 2020 999br>David Hume" ''Encyclopædia Britannica''. Retrieved 18 May 2020. was a Scottish Enlightenment philosopher, historian, economist, librarian, and essayist, who is best known today for his highly influential system of philosophical empiricism, scepticism, and naturalism. Beginning with '' A Treatise of Human Nature'' (1739–40), Hume strove to create a naturalistic science of man that examined the psychological basis of human nature. Hume argued against the existence of innate ideas, positing that all human knowledge derives solely from experience. This places him with Francis Bacon, Thomas Hobbes, John Locke, and George Berkeley as an Empiricist. Hume argued that inductive reasoning and belief in causality cannot be justified rationally; instead, they result from custom and mental habit. We never actually perceive that one ev ...

Hume's Fork
Hume's fork, in epistemology, is a tenet elaborating upon British empiricist philosopher David Hume's emphatic, 1730s division between "relations of ideas" versus "matters of fact."Antony Flew, ''A Dictionary of Philosophy'', rev 2nd edn (New York: St Martin's Press, 1984)p. 156 Georges Dickerch. 2 "Hume's theory of knowledge (I): 'Hume's fork' " Hume's Epistemology and Metaphysics: An Introduction' (London & New York: Routledge, 1998)p. 41introducing Kant's formulation of Hume's fork. (Alternatively, ''Hume's fork'' may refer to what is otherwise termed '' Hume's law'', a tenet of ethics.) As phrased in Immanuel Kant's 1780s characterization of Hume's thesis, and furthered in the 1930s by the logical empiricists, Hume's fork asserts that all statements are exclusively either "analytic ''a priori''" or "synthetic ''a posteriori''," which, respectively, are universally true by mere ''definition'' or, however apparently probable, are unknowable without exact ''experience''.

Ethical Naturalist
Ethical naturalism (also called moral naturalism or naturalistic cognitivistic definism) is the meta-ethical view which claims that: # Ethical sentences express propositions. # Some such propositions are true. # Those propositions are made true by objective features of the world. # These moral features of the world ''are'' reducible to some set of non-moral features. Overview The versions of ethical naturalism which have received the most sustained philosophical interest, for example, Cornell realism, differ from the position that "the way things are is always the way they ought to be", which few ethical naturalists hold. Ethical naturalism does, however, reject the fact-value distinction: it suggests that inquiry into the natural world can increase our moral knowledge in just the same way it increases our scientific knowledge. Indeed, proponents of ethical naturalism have argued that humanity needs to invest in the science of morality, a broad and loosely defined field that ...

Ethical Non-naturalist
Ethical non-naturalism (or moral non-naturalism) is the meta-ethical view which claims that: # Ethical sentences express propositions. # Some such propositions are true. # Those propositions are made true by objective features of the world, independent of human opinion. # These moral features of the world are ''not'' reducible to any set of non-moral features. This makes ethical non-naturalism a non-definist form of moral realism, which is in turn a form of cognitivism. Ethical non-naturalism stands in opposition to ethical naturalism, which claims that moral terms and properties are reducible to non-moral terms and properties, as well as to all forms of moral anti-realism, including ethical subjectivism (which denies that moral propositions refer to objective facts), error theory (which denies that any moral propositions are true), and non-cognitivism (which denies that moral sentences express propositions at all).

Brute Fact
In contemporary philosophy, a brute fact is a fact that cannot be explained in terms of a deeper, more "fundamental" fact. There are two main ways to explain something: say what "brought it about", or describe it at a more "fundamental" level. For example, a cat displayed on a computer screen can be explained, more "fundamentally", in terms of certain voltages in bits of metal in the screen, which in turn can be explained, more "fundamentally", in terms of certain subatomic particles moving in a certain manner. If one were to keep explaining the world in this way and reach a point at which no more "deeper" explanations can be given, then one would have found some facts which are brute or inexplicable, in the sense that we cannot give them an ontological explanation. As it might be put, there may exist some things that just ''are''. To reject the existence of brute facts is to think that everything can be explained ("Everything can be explained" is sometimes called the principle of ...

Moral Realism
Moral realism (also ethical realism) is the position that ethical sentences express propositions that refer to objective features of the world (that is, features independent of subjective opinion), some of which may be true to the extent that they report those features accurately. This makes moral realism a non- nihilist form of ethical cognitivism (which accepts that ethical sentences express propositions and can therefore be evaluated as true or false) with an ontological orientation, standing in opposition to all forms of moral anti-realism and moral skepticism, including ethical subjectivism (which denies that moral propositions refer to objective facts), error theory (which denies that any moral propositions are true); and non-cognitivism (which denies that moral sentences express propositions at all). Within moral realism, the two main subdivisions are ethical naturalism and ethical non-naturalism. Many philosophers claim that moral realism may be dated back at least ...

Presupposition
In the branch of linguistics known as pragmatics, a presupposition (or PSP) is an implicit assumption about the world or background belief relating to an utterance whose truth is taken for granted in discourse. Examples of presuppositions include: * ''Jane no longer writes fiction.'' ** Presupposition: Jane once wrote fiction. * ''Have you stopped eating meat?'' ** Presupposition: you had once eaten meat. * ''Have you talked to Hans?'' ** Presupposition: Hans exists. A presupposition must be mutually known or assumed by the speaker and addressee for the utterance to be considered appropriate in context. It will generally remain a necessary assumption whether the utterance is placed in the form of an assertion, denial, or question, and can be associated with a specific lexical item or grammatical feature (presupposition trigger) in the utterance. Crucially, negation of an expression does not change its presuppositions: ''I want to do it again'' and ''I don't want to do it again'' ...

Telos (philosophy)
Telos (; ) is a term used by philosopher Aristotle to refer to the final cause of a natural organ or entity, or of a work of human art. Intentional actualization of potential or inherent purpose,"Telos.''Philosophy Terms'' Retrieved 3 May 2020. similar to the notion of an 'end goal' or ''. Moreover, it can be understood as the "supreme end of man's endeavour". ''Telos'' is the root of the modern term teleology, the study of purposiveness or of objects with a view to their aims, purposes, or intentions. Teleology is central in Aristotle's work on plant and animal biology, and human ethics, through his theory of the four causes. Aristotle's notion that everything has a ''telos'' also gave rise to epistemology. Applied to philosophical theories of history, it refers to a messianic redemption or some other utopia, such as postulated by Christian salvation history, or in the schools of thought of Georg Wilhelm Friedrich Hegel and Karl Marx. In general philosophy ''Telos'' has bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Evolution
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes, which are passed on from parent to offspring during reproduction. Variation tends to exist within any given population as a result of genetic mutation and recombination. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on this variation, resulting in certain characteristics becoming more common or more rare within a population. The evolutionary pressures that determine whether a characteristic is common or rare within a population constantly change, resulting in a change in heritable characteristics arising over successive generations. It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms, and molecules.

Dialectical Naturalism
Murray Bookchin (January 14, 1921 – July 30, 2006) was an American social theorist, author, orator, historian, and political philosopher. A pioneer in the environmental movement, Bookchin formulated and developed the theory of social ecology and urban planning within anarchist, libertarian socialist, and ecological thought. He was the author of two dozen books covering topics in politics, philosophy, history, urban affairs, and social ecology. Among the most important were ''Our Synthetic Environment'' (1962), ''Post-Scarcity Anarchism'' (1971), '' The Ecology of Freedom'' (1982) and ''Urbanization Without Cities'' (1987). In the late 1990s, he became disenchanted with what he saw as an increasingly apolitical " lifestylism" of the contemporary anarchist movement, stopped referring to himself as an anarchist, and founded his own libertarian socialist ideology called "communalism", which seeks to reconcile and expand Marxist, syndicalist, and anarchist thought.

Category Error
A category mistake, or category error, or categorical mistake, or mistake of category, is a semantic or ontological error in which things belonging to a particular category are presented as if they belong to a different category, or, alternatively, a property is ascribed to a thing that could not possibly have that property. An example is a person learning that the game of cricket involves team spirit, and after being given a demonstration of each player's role, asking which player performs the "team spirit". Unlike bowling or batting, team spirit is not a task in the game but an aspect of how the team behaves as a group. To show that a category mistake has been committed one must typically show that once the phenomenon in question is properly understood, it becomes clear that the claim being made about it could not possibly be true. Gilbert Ryle The term "category-mistake" was introduced by Gilbert Ryle in his book ''The Concept of Mind'' (1949) to remove what he argued to be ...
