Reasons Behind
In the most general terms, a reason is a consideration which justifies or explains an action, a belief, an attitude, or a fact. '' Normative reasons'' are what people appeal to when making arguments about what people should do or believe. For example, that a doctor's patient is grimacing is a reason to believe the patient is in pain. That the patient is in pain is a reason for the doctor to do things to alleviate the pain. Explanatory reasons are explanations of why things happened. For example, the reason the patient is in pain is that her nerves are sending signals from her tissues to her brain. A reason, in many cases, is brought up by the question "why?", and answered following the word ''because''. Additionally, words and phrases such as ''since'', ''due to'', ''as'', ''considering'' (''that''), ''a result'' (''of''), and ''in order to'', for example, all serve as explanatory locutions that precede the reason to which they refer. Types of reason In philosophy, it is common ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Normativity
Normative generally means relating to an evaluative standard. Normativity is the phenomenon in human societies of designating some actions or outcomes as good, desirable, or permissible, and others as bad, undesirable, or impermissible. A norm in this normative sense means a standard for evaluating or making judgments about behavior or outcomes. Normative is sometimes also used, somewhat confusingly, to mean relating to a descriptive standard: doing what is normally done or what most others are expected to do in practice. In this sense a norm is not evaluative, a basis for judging behavior or outcomes; it is simply a fact or observation about behavior or outcomes, without judgment. Many researchers in science, law, and philosophy try to restrict the use of the term normative to the evaluative sense and refer to the description of behavior and outcomes as positive, descriptive, predictive, or empirical. ''Normative'' has specialised meanings in different academic disciplines such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argument
An argument is a statement or group of statements called premises intended to determine the degree of truth or acceptability of another statement called conclusion. Arguments can be studied from three main perspectives: the logical, the dialectical and the rhetorical perspective. In logic, an argument is usually expressed not in natural language but in a symbolic formal language, and it can be defined as any group of propositions of which one is claimed to follow from the others through deductively valid inferences that preserve truth from the premises to the conclusion. This logical perspective on argument is relevant for scientific fields such as mathematics and computer science. Logic is the study of the forms of reasoning in arguments and the development of standards and criteria to evaluate arguments. Deductive arguments can be valid, and the valid ones can be sound: in a valid argument, premisses necessitate the conclusion, even if one or more of the premises is false ...

Derek Parfit
Derek Antony Parfit (; 11 December 1942 – 1 or 2 January 2017) was a British philosopher who specialised in personal identity, rationality, and ethics. He is widely considered one of the most important and influential moral philosophers of the late 20th and early 21st centuries. Parfit rose to prominence in 1971 with the publication of his first paper, "Personal Identity". His first book, ''Reasons and Persons'' (1984), has been described as the most significant work of moral philosophy since the 1800s. His second book, ''On What Matters'' (2011), was widely circulated and discussed for many years before its publication. For his entire academic career, Parfit worked at Oxford University, where he was an Emeritus Senior Research Fellow at All Souls College at the time of his death. He was also a visiting professor of philosophy at Harvard University, New York University, and Rutgers University. He was awarded the 2014 Rolf Schock Prize "for his groundbreaking contributions c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rational Agent
A rational agent or rational being is a person or entity that always aims to perform optimal actions based on given premises and information. A rational agent can be anything that makes decisions, typically a person, firm, machine, or software. The concept of rational agents can be found in various disciplines such as artificial intelligence, cognitive science, decision theory, economics, ethics, game theory, and the study of practical reason. Economics In reference to economics, rational agent refers to hypothetical consumers and how they make decisions in a free market. This concept is one of the assumptions made in neoclassical economic theory. The concept of economic rationality arises from a tradition of marginal analysis used in neoclassical economics. The idea of a rational agent is important to the philosophy of utilitarianism, as detailed by philosopher Jeremy Bentham's theory of the felicific calculus, also known as the hedonistic calculus. The action a rational age ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Broome (philosopher)
John Broome (born 1947) is a British philosopher and economist. He was the White's Professor of Moral Philosophy at the University of Oxford and a Fellow of Corpus Christi College, Oxford. Biography Broome was educated at the University of Cambridge, at the University of London and at the Massachusetts Institute of Technology, where he received a PhD in economics. Before arriving at Oxford he was Professor of Philosophy at the University of St. Andrews and, prior to that, Professor of Economics and Philosophy at the University of Bristol. He has held visiting posts at the University of Virginia, the Australian National University, Princeton University, the University of Washington, the University of British Columbia, the Swedish Collegium for Advanced Study in the Social Sciences, and the University of Canterbury. In 2007 Broome was elected a Foreign Member of the Royal Swedish Academy of Sciences. His book ''Weighing Goods'' (1991) explores the way in which goods "located" in ...

Norm (philosophy)
Norms are concepts ( sentences) of practical import, oriented to affecting an action, rather than conceptual abstractions that describe, explain, and express. Normative sentences imply "ought-to" types of statements and assertions, in distinction to sentences that provide "is" types of statements and assertions. Common normative sentences include commands, permissions, and prohibitions; common normative abstract concepts include ''sincerity'', ''justification'', and ''honesty''. A popular account of norms describes them as reasons to take action, to believe, and to feel. Types of norms Orders and permissions express norms. Such norm sentences do not describe how the world is, they rather prescribe how the world should be. Imperative sentences are the most obvious way to express norms, but declarative sentences also may be norms, as is the case with laws or 'principles'. Generally, whether an expression is a norm depends on what the sentence intends to assert. For instance, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Informal Logic
Informal logic encompasses the principles of logic and logical thought outside of a formal setting (characterized by the usage of particular statements). However, the precise definition of "informal logic" is a matter of some dispute. Ralph H. Johnson and J. Anthony Blair define informal logic as "a branch of logic whose task is to develop non-formal standards, criteria, procedures for the analysis, interpretation, evaluation, criticism and construction of argumentation."Johnson, Ralph H., and Blair, J. Anthony (1987), "The Current State of Informal Logic", ''Informal Logic'', 9(2–3), 147–151. Johnson & Blair added "... in everyday discourse" but in (2000), modified their definition, and broadened the focus now to include the sorts of argument that occurs not just in everyday discourse but also disciplined inquiry—what Weinstein (1990) calls "stylized discourse." This definition reflects what had been implicit in their practice and what others were doing in their informal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Premise
A premise or premiss is a true or false statement that helps form the body of an argument, which logically leads to a true or false conclusion. A premise makes a declarative statement about its subject matter which enables a reader to either agree or disagree with the premise in question, and in doing so understand the logical assumptions of the argument. If a premise is logically false, then the conclusion, which follows from all of the premises of the argument, must also be false—unless the conclusion is supported by a logically valid argument which the reader agrees with. Therefore, if the reader disagrees with any one of the argument's premises, they have a logical basis to reject the conclusion of the argument. Explanation In logic, an argument requires a set of at least two declarative sentences (or "propositions") known as the "premises" (or "premisses"), along with another declarative sentence (or "proposition"), known as the conclusion. This structure of two prem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Co-premise
A co-premise is a premise in reasoning and informal logic which is not the main supporting reason for a contention or a lemma, but is logically necessary to ensure the validity of an argument. One premise by itself, or a group of co-premises can form a reason. Logical structure Every significant term or phrase appearing in a premise of a simple argument, should also appear in the contention/conclusion or in a co-premise. But this by itself does not guarantee a valid argument, see the fallacy of the undistributed middle for an example of this. Sometimes a co-premise will not be explicitly stated. This type of argument is known as an 'enthymematic' argument, and the co-premise may be referred to as a 'hidden' or an 'unstated' co-premise and will often be subject to an inference objection. In this argument map An argument map or argument diagram is a visual representation of the structure of an argument. An argument map typically includes the key components of the argument, tr ...

Logic
Logic is the study of correct reasoning. It includes both formal and informal logic. Formal logic is the science of deductively valid inferences or of logical truths. It is a formal science investigating how conclusions follow from premises in a topic-neutral way. When used as a countable noun, the term "a logic" refers to a logical formal system that articulates a proof system. Formal logic contrasts with informal logic, which is associated with informal fallacies, critical thinking, and argumentation theory. While there is no general agreement on how formal and informal logic are to be distinguished, one prominent approach associates their difference with whether the studied arguments are expressed in formal or informal languages. Logic plays a central role in multiple fields, such as philosophy, mathematics, computer science, and linguistics. Logic studies arguments, which consist of a set of premises together with a conclusion. Premises and conclusions are usually un ...
