Non-cognitivism
Non-cognitivism is the meta-ethical view that ethical sentences do not express propositions (i.e., statements) and thus cannot be true or false (they are not truth-apt). A noncognitivist denies the cognitivist claim that "moral judgments are capable of being objectively true, because they describe some feature of the world". If moral statements cannot be true, and if one cannot know something that is not true, noncognitivism implies that moral knowledge is impossible. Non-cognitivism entails that non-cognitive attitudes underlie moral discourse and this discourse therefore consists of non-declarative speech acts, although accepting that its surface features may consistently and efficiently work as if moral discourse were cognitive. The point of interpreting moral claims as non-declarative speech acts is to explain what moral claims mean if they are neither true nor false (as philosophies such as logical positivism entail). Utterances like "Boo to killing!" and "Don't kill" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meta-ethics
In metaphilosophy and ethics, meta-ethics is the study of the nature, scope, and meaning of moral judgment. It is one of the three branches of ethics generally studied by philosophers, the others being normative ethics (questions of how one ought to be and act) and applied ethics (practical questions of right behavior in given, usually contentious, situations). While normative ethics addresses such questions as "What should I do?", evaluating specific practices and principles of action, meta-ethics addresses questions such as "What ''is'' goodness?" and "How can we tell what is good from what is bad?", seeking to understand the assumptions underlying normative theories. Another distinction often made is that normative ethics involves first-order or substantive questions; meta-ethics involves second-order or formal questions. Some theorists argue that a metaphysical account of morality is necessary for the proper evaluation of actual moral theories and for making practical mo ...

Cognitivism (ethics)
Cognitivism is the meta-ethical view that ethical sentences express propositions and can therefore be true or false (they are truth-apt), which noncognitivists deny. Cognitivism is so broad a thesis that it encompasses (among other views) moral realism (which claims that ethical sentences express propositions about mind-independent facts of the world), ethical subjectivism (which claims that ethical sentences express propositions about peoples' attitudes or opinions), and error theory (which claims that ethical sentences express propositions, but that they are all false, whatever their nature). Overview Propositions are what meaningful declarative sentences (but not interrogative or imperative sentences) are supposed to ''express''. Different sentences, in different languages, can express the same proposition: "snow is white" and "Schnee ist weiß" (in German) both express the proposition that snow is white. A common belief among philosophers who use this jargon is that pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amoralism
Moral nihilism (also known as ethical nihilism) is the meta-ethical view that nothing is morally right or wrong. Moral nihilism is distinct from moral relativism, which allows for actions to be wrong relative to a particular culture or individual. It is also distinct from expressivism, according to which when we make moral claims, "We are not making an effort to describe the way the world is ... we are venting our emotions, commanding others to act in certain ways, or revealing a plan of action". Moral nihilism today broadly tends to take the form of an Error Theory: The view developed originally by J.L. Mackie in his 1977 book ''Ethics: Inventing Right and Wrong''. Error theory and nihilism broadly take the form of a ''negative claim'' about the existence of objective values or properties. Under traditional views there are moral properties or methods which hold objectively in some sense beyond our contingent interests which morally obligate us to act. For Mackie and the Erro ...

Universal Prescriptivism
Universal prescriptivism (often simply called prescriptivism) is the meta-ethical view that claims that, rather than expressing propositions, ethical sentences function similarly to imperatives which are universalizable—whoever makes a moral judgment is committed to the same judgment in any situation where the same relevant facts pertain. This makes prescriptivism a universalist form of non-cognitivism. Prescriptivism stands in opposition to other forms of non-cognitivism (such as emotivism and quasi-realism), as well as to all forms of cognitivism (including both moral realism and ethical subjectivism). Since prescriptivism was introduced by philosopher R. M. Hare in his 1952 book ''The Language of Morals'', it has been compared to emotivism and to the categorical imperative of Immanuel Kant. Unlike Kant, however, Hare does not invoke universalizability as a test of moral permissibility. Instead, he sees it as a consistency requirement that is built into the logic ...

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 ...

Naturalistic Fallacy
In philosophical ethics, the naturalistic fallacy is the claim that any reductive explanation of good, in terms of natural properties such as ''pleasant'' or ''desirable'', is false. The term was introduced by British philosopher G. E. Moore in his 1903 book ''Principia Ethica''. Moore's naturalistic fallacy is closely related to the is–ought problem, which comes from David Hume's ''A Treatise of Human Nature'' (1738–40). However, unlike Hume's view of the is–ought problem, Moore (and other proponents of ethical non-naturalism) did not consider the naturalistic fallacy to be at odds with moral realism. The ''naturalistic fallacy'' should not be confused with the '' appeal to nature'', which is exemplified by forms of reasoning such as "Something is natural; therefore, it is morally acceptable" or "This property is unnatural; therefore, this property is undesirable." Such inferences are common in discussions of medicine, sexuality, environmentalism, gender roles, race, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperative Logic
Imperative logic is the field of logic concerned with imperatives. In contrast to declaratives, it is not clear whether imperatives denote propositions or more generally what role truth and falsity play in their semantics. Thus, there is almost no consensus on any aspect of imperative logic. Jørgensen's dilemma One of a logic's principal concerns is logical validity. It seems that arguments with imperatives can be valid. Consider: :P1. Take all the books off the table! :P2. ''Foundations of Arithmetic'' is on the table. :C1. Therefore, take ''Foundations of Arithmetic'' off the table! However, an argument is valid if the conclusion follows from the premises. This means the premises give us reason to believe the conclusion, or, alternatively, the truth of the premises determines truth of the conclusion. Since imperatives are neither true nor false and since they are not proper objects of belief, none of the standard accounts of logical validity apply to arguments containing imp ...

Hercules At The Crossroads
Hercules at the crossroads, also known as the Choice of Hercules and the Judgement of Hercules, is an ancient Greek parable attributed to Prodicus and known from Xenophon. It concerns the young Heracles/Hercules who is offered a choice between Vice and Virtue—a life of pleasure or one of hardship and honour. In the early modern period it became a popular motif in Western art. History Classical period The parable stems from the Classical era of ancient Greece and is reported by Xenophon in ''Memorabilia'' 2.1.21–34. In Xenophon's text, Socrates tells how the young Heracles, as the hero contemplates his future, is visited by the female personifications of Vice and Virtue (Ancient Greek: Κακία and Ἀρετή; '' Kakía'' and ''Areté''). They offer him a choice between a pleasant and easy life or a severe but glorious life, and present their respective arguments. Xenophon credits the invention of the parable to Prodicus. He cites a precursor in Hesiod's ''Works and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Categorical Imperative
The categorical imperative (german: kategorischer Imperativ) is the central philosophical concept in the deontological moral philosophy of Immanuel Kant. Introduced in Kant's 1785 '' Groundwork of the Metaphysic of Morals'', it is a way of evaluating motivations for action. It is best known in its original formulation: "Act only according to that maxim whereby you can, at the same time, will that it should become a universal law."It is standard to also reference the '' Akademie Ausgabe'' of Kant's works. The ''Groundwork'' occurs in the fourth volume. Citations throughout this article follow the format 4:x. For example, the above citation is taken from 4:421. According to Kant, sentient beings occupy a special place in creation, and morality can be summed up in an imperative, or ultimate commandment of reason, from which all duties and obligations derive. He defines an ''imperative'' as any proposition declaring a certain action (or inaction) to be necessary. Hypothetical imp ...

Ten Commandments
The Ten Commandments (Biblical Hebrew עשרת הדברים \ עֲשֶׂרֶת הַדְּבָרִים, ''aséret ha-dvarím'', lit. The Decalogue, The Ten Words, cf. Mishnaic Hebrew עשרת הדיברות \ עֲשֶׂרֶת הַדִּבְּרוֹת, ''aséret ha-dibrót'', lit. The Decalogue, The Ten Words), are a set of biblical principles relating to ethics and worship that play a fundamental role in Judaism and Christianity. The text of the Ten Commandments appears twice in the Hebrew Bible: at Exodus and Deuteronomy . According to the Book of Exodus in the Torah, the Ten Commandments were revealed to Moses at Mount Sinai and inscribed by the finger of God on two tablets of stone kept in the Ark of the Covenant. Scholars disagree about when the Ten Commandments were written and by whom, with some modern scholars suggesting that they were likely modeled on Hittite and Mesopotamian laws and treaties.

Tautology (logic)
In mathematical logic, a tautology (from el, ταυτολογία) is a formula or assertion that is true in every possible interpretation. An example is "x=y or x≠y". Similarly, "either the ball is green, or the ball is not green" is always true, regardless of the colour of the ball. The philosopher Ludwig Wittgenstein first applied the term to redundancies of propositional logic in 1921, borrowing from rhetoric, where a tautology is a repetitive statement. In logic, a formula is satisfiable if it is true under at least one interpretation, and thus a tautology is a formula whose negation is unsatisfiable. In other words, it cannot be false. It cannot be untrue. Unsatisfiable statements, both through negation and affirmation, are known formally as contradictions. A formula that is neither a tautology nor a contradiction is said to be logically contingent. Such a formula can be made either true or false based on the values assigned to its propositional variables. The dou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
