Ethics is the philosophical study of moral phenomena. Also called moral philosophy, it investigates normative questions about what people ought to do or which behavior is morally right. The main branches of ethics include normative ethics, applied ethics, and metaethics.
In metaphilosophy and ethics, metaethics 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 and applied ethics.
Philosophy of law is a branch of philosophy that examines the nature of law and law's relationship to other systems of norms, especially ethics and political philosophy. It asks questions like "What is law?", "What are the criteria for legal validity?", and "What is the relationship between law and morality?" Philosophy of law and jurisprudence are often used interchangeably, though jurisprudence sometimes encompasses forms of reasoning that fit into economics or sociology.
In ethics and the social sciences, value theory involves various approaches that examine how, why, and to what degree humans value things and whether the object or subject of valuing is a person, idea, object, or anything else. Within philosophy, it is also known as ethics or axiology.
Rights are legal, social, or ethical principles of freedom or entitlement; that is, rights are the fundamental normative rules about what is allowed of people or owed to people according to some legal system, social convention, or ethical theory. Rights are of essential importance in such disciplines as law and ethics, especially theories of justice and deontology.
Rationality is the quality of being guided by or based on reason. In this regard, a person acts rationally if they have a good reason for what they do, or a belief is rational if it is based on strong evidence. This quality can apply to an ability, as in a rational animal, to a psychological process, like reasoning, to mental states, such as beliefs and intentions, or to persons who possess these other forms of rationality. A thing that lacks rationality is either arational, if it is outside the domain of rational evaluation, or irrational, if it belongs to this domain but does not fulfill its standards.
Positive is a property of positivity and may refer to:
Law and economics, or economic analysis of law, is the application of microeconomic theory to the analysis of law. The field emerged in the United States during the early 1960s, primarily from the work of scholars from the Chicago school of economics such as Aaron Director, George Stigler, and Ronald Coase. The field uses economics concepts to explain the effects of laws, to assess which legal rules are economically efficient, and to predict which legal rules will be promulgated. There are two major branches of law and economics; one based on the application of the methods and theories of neoclassical economics to the positive and normative analysis of the law, and a second branch which focuses on an institutional analysis of law and legal institutions, with a broader focus on economic, political, and social outcomes, and overlapping with analyses of the institutions of politics and governance.
Descriptive ethics, also known as comparative ethics, is the study of people's beliefs about morality. It contrasts with prescriptive or normative ethics, which is the study of ethical theories that prescribe how people ought to act, and with meta-ethics, which is the study of what ethical terms and theories actually refer to. The following examples of questions that might be considered in each field illustrate the differences between the fields:
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 positive statements and prescriptive or normative statements, and that it is not obvious how one can coherently transition from descriptive statements to prescriptive ones. Hume's law or Hume's guillotine is the thesis that an ethical or judgmental conclusion cannot be inferred from purely descriptive factual statements.
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 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.
Decision theory is a branch of applied probability theory and analytic philosophy concerned with the theory of making decisions based on assigning probabilities to various factors and assigning numerical consequences to the outcome.
Positive economics is the part of economics that deals with positive statements. Positive economics, was originated from positivism and got introduced to economics by John Stuart Mill in his book Auguste Comte and Positivism in 1860's, reflecting upon Comte's positivism. Then, it was developed by John Neville Keynes in the 1890's and it became popular economical thought by elaborations of Lionel Robbins in the 1930s. In essence, positive economics studies what is rather than what ought to be. While economics can be filled with subjective statements such as value and allocation, it is vital to distinguish that what be is not objectively permanent or desirable.
Normative economics is the part of economics that deals with normative statements. It focuses on the idea of fairness and what the outcome of the economy or goals of public policy ought to be.
Naturalized epistemology is a collection of philosophic views about the theory of knowledge that emphasize the role of natural scientific methods. This shared emphasis on scientific methods of studying knowledge shifts the focus of epistemology away from many traditional philosophical questions, and towards the empirical processes of knowledge acquisition. There are noteworthy distinctions within naturalized epistemology. Replacement naturalism maintains that we should abandon traditional epistemology and replace it with the methodologies of the natural sciences. The general thesis of cooperative naturalism is that traditional epistemology can benefit in its inquiry by using the knowledge we have gained from cognitive sciences. Substantive naturalism focuses on an asserted equality of facts of knowledge and natural facts.
Philosophy and economics studies topics such as public economics, behavioural economics, rationality, justice, history of economic thought, rational choice, the appraisal of economic outcomes, institutions and processes, the status of highly idealized economic models, the ontology of economic phenomena and the possibilities of acquiring knowledge of them.
Positive accounting is the branch of academic accounting research that seeks to explain and predict actual accounting practices. This contrasts with normative accounting, that seeks to derive and prescribe "optimal" accounting standards.
Applied economics is the application of economic theory and econometrics in specific settings. As one of the two sets of fields of economics, it is typically characterized by the application of the core, i.e. economic theory and econometrics to address practical issues in a range of fields including demographic economics, labour economics, business economics, industrial organization, agricultural economics, development economics, education economics, engineering economics, financial economics, health economics, monetary economics, public economics, and economic history. From the perspective of economic development, the purpose of applied economics is to enhance the quality of business practices and national policy making.
Milton Friedman's book Essays in Positive Economics (1953) is a collection of earlier articles by the author with as its lead an original essay "The Methodology of Positive Economics." This essay posits Friedman's famous, but controversial, principle that assumptions need not be "realistic" to serve as scientific hypotheses; they merely need to make significant predictions.
Constitutional economics is a research program in economics and constitutionalism that has been described as explaining the choice "of alternative sets of legal-institutional-constitutional rules that constrain the choices and activities of economic and political agents". This extends beyond the definition of "the economic analysis of constitutional law" and is distinct from explaining the choices of economic and political agents within those rules, a subject of orthodox economics. Instead, constitutional economics takes into account the impacts of political economic decisions as opposed to limiting its analysis to economic relationships as functions of the dynamics of distribution of marketable goods and services.
