Theory-ladenness
In the philosophy of science, observations are said to be "theory-laden" when they are affected by the theoretical presuppositions held by the investigator. The thesis of theory-ladenness is most strongly associated with the late 1950s and early 1960s work of Norwood Russell Hanson, Thomas Kuhn, and Paul Feyerabend, and was probably first put forth (at least implicitly) by Pierre Duhem about 50 years earlier.
Non-science
A non-science is an area of study that is not scientific, especially one that is not a natural science or a social science that is an object of scientific inquiry. In this model, history, art, and religion are all examples of non-sciences. Demarcation problem Since the 17th century, some writers have used the word science to exclude some areas of studies, such as the arts and the liberal arts. The word nonscience, to describe non-scientific academic disciplines, was first used in the middle of the 19th century.
Social philosophy
Social philosophy examines questions about the foundations of social institutions, social behavior, and interpretations of society in terms of ethical values rather than empirical relations. Social philosophers emphasize understanding the social contexts for political, legal, moral and cultural questions, and the development of novel theoretical frameworks, from social ontology to care ethics to cosmopolitan theories of democracy, natural law, human rights, gender equity and global justice.
Inductivism
Inductivism is the traditional and still commonplace philosophy of scientific method to develop scientific theories. Inductivism aims to neutrally observe a domain, infer laws from examined cases—hence, inductive reasoning—and thus objectively discover the sole naturally true theory of the observed. Inductivism's basis is, in sum, "the idea that theories can be derived from, or established on the basis of, facts".
Münchhausen trilemma
In epistemology, the Münchhausen trilemma is a thought experiment intended to demonstrate the theoretical impossibility of proving any truth, even in the fields of logic and mathematics, without appealing to accepted assumptions. If it is asked how any given proposition is known to be true, proof in support of that proposition may be provided. Yet that same question can be asked of that supporting proof, and any subsequent supporting proof.
Verisimilitude
In philosophy, verisimilitude (or truthlikeness) is the notion that some propositions are closer to being true than other propositions. The problem of verisimilitude is the problem of articulating what it takes for one false theory to be closer to the truth than another false theory. This problem was central to the philosophy of Karl Popper, largely because Popper was among the first to affirm that truth is the aim of scientific inquiry while acknowledging that most of the greatest scientific theories in the history of science are, strictly speaking, false.
New class
New class is a polemic term by critics of countries that followed the Soviet-type state socialism to describe the privileged ruling class of bureaucrats and Communist party functionaries which arose in these states. Generally, the group known in the Soviet Union as the nomenklatura conforms to the theory of the new class. The term was earlier applied to other emerging strata of the society. Milovan Đilas' new-class theory was also used extensively by anti-communist commentators in the Western world in their criticism of the Communist states during the Cold War.
Open society
Open society (société ouverte) is a term coined by French philosopher Henri Bergson in 1932, and describes a dynamic system inclined to moral universalism. Bergson contrasted an open society with what he called a closed society, a closed system of law, morality or religion. Bergson suggests that if all traces of civilization were to disappear, the instincts of the closed society for including or excluding others would remain. The idea of an open society was further developed during World War II by the Austrian-born British philosopher Karl Popper.
Positivism dispute
The positivism dispute (Positivismusstreit) was a political-philosophical dispute between the critical rationalists (Karl Popper, Hans Albert) and the Frankfurt School (Theodor Adorno, Jürgen Habermas) in 1961, about the methodology of the social sciences. It grew into a broad discussion within German sociology from 1961 to 1969. The naming itself is controversial, since it was the Frankfurt School proponents who accused the critical rationalists of being positivists—while the latter considered themselves to be opponents of positivism.
Historism
Historism (Italian: storicismo) is a philosophical and historiographical theory, founded in 19th-century Germany (as Historismus) and especially influential in 19th- and 20th-century Europe. In those times there was not a single natural, humanistic or philosophical science that would not reflect, in one way or another, the historical type of thought (cf. comparative historical linguistics etc.). It pronounces the historicity of humanity and its binding to tradition.
