Falsifiability is a deductive standard of evaluation of scientific theories and hypotheses, introduced by the philosopher of science Karl Popper in his book The Logic of Scientific Discovery (1934). A theory or hypothesis is falsifiable if it can be logically contradicted by an empirical test.
Historicism is an approach to explaining the existence of phenomena, especially social and cultural practices, by studying the process or history by which they came about. The term is widely used in philosophy, anthropology, and sociology.
Sir Karl Raimund Popper was an Austrian–British philosopher, academic and social commentator. One of the 20th century's most influential philosophers of science, Popper is known for his rejection of the classical inductivist views on the scientific method in favour of empirical falsification. According to Popper, a theory in the empirical sciences can never be proven, but it can be falsified, meaning that it can be scrutinised with decisive experiments. Popper was opposed to the classical justificationist account of knowledge, which he replaced with critical rationalism, namely "the first non-justificational philosophy of criticism in the history of philosophy".
The problem of induction is a philosophical problem that questions the rationality of predictions about unobserved things based on previous observations. These inferences from the observed to the unobserved are known as "inductive inferences". David Hume, who first formulated the problem in 1739, argued that there is no non-circular way to justify inductive inferences, while acknowledging that everyone does and must make such inferences.
Open society 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.
Critical rationalism is an epistemological philosophy advanced by Karl Popper on the basis that, if a statement cannot be logically deduced, it might nevertheless be possible to logically falsify it. Following Hume, Popper rejected any inductive logic that is ampliative, i.e., any logic that can provide more knowledge than deductive logic. This led Popper to his falsifiability criterion.
The principle of rationality was coined by Karl R. Popper in his Harvard Lecture of 1963, and published in his book Myth of Framework. It is related to what he called the 'logic of the situation' in an Economica article of 1944/1945, published later in his book The Poverty of Historicism. According to Popper's rationality principle, agents act in the most adequate way according to the objective situation. It is an idealized conception of human behavior which he used to drive his model of situational analysis. Cognitive scientist Allen Newell elaborated on the principle in his account of knowledge level modeling.
The Open Society and Its Enemies is a work on political philosophy by the philosopher Karl Popper, in which the author presents a "defence of the open society against its enemies", and offers a critique of theories of teleological historicism, according to which history unfolds inexorably according to universal laws. Popper indicts Plato, Hegel, and Marx for relying on historicism to underpin their political philosophies.
Evolutionary epistemology refers to three distinct topics: (1) the biological evolution of cognitive mechanisms in animals and humans, (2) a theory that knowledge itself evolves by natural selection, and (3) the study of the historical discovery of new abstract entities such as abstract number or abstract value that necessarily precede the individual acquisition and usage of such abstractions. As a branch of inquiry in epistemology, evolutionary epistemology lies at the crossroads of philosophy and evolutionary biology.
Positivism is a philosophical school that holds that all genuine knowledge is either true by definition or positive – meaning a posteriori facts derived by reason and logic from sensory experience. Other ways of knowing, such as intuition, introspection, or religious faith, are rejected or considered meaningless.
Verificationism, also known as the verification principle or the verifiability criterion of meaning, is a doctrine in philosophy which asserts that a statement is meaningful only if it is either empirically verifiable or a tautology. Verificationism rejects statements of metaphysics, theology, ethics and aesthetics as meaningless in conveying truth value or factual content, though they may be meaningful in influencing emotions or behavior.
Models of scientific inquiry have two functions: first, to provide a descriptive account of how scientific inquiry is carried out in practice, and second, to provide an explanatory account of why scientific inquiry succeeds as well as it appears to do in arriving at genuine knowledge. The philosopher Wesley C. Salmon described scientific inquiry:
The search for scientific knowledge ends far back into antiquity. At some point in the past, at least by the time of Aristotle, philosophers recognized that a fundamental distinction should be drawn between two kinds of scientific knowledge—roughly, knowledge that and knowledge why. It is one thing to know that each planet periodically reverses the direction of its motion with respect to the background of fixed stars; it is quite a different matter to know why. Knowledge of the former type is descriptive; knowledge of the latter type is explanatory. It is explanatory knowledge that provides scientific understanding of the world.
The positivism dispute was a political-philosophical dispute between the critical rationalists and the Frankfurt School 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.
Criticism of Marxism has come from various political ideologies, campaigns and academic disciplines. This includes general intellectual criticism about dogmatism, a lack of internal consistency, criticism related to materialism, arguments that Marxism is a type of historical determinism or that it necessitates a suppression of individual rights, issues with the implementation of communism and economic issues such as the distortion or absence of price signals and reduced incentives. In addition, empirical and epistemological problems are frequently identified.
Historism is a philosophical and historiographical theory, founded in 19th-century Germany 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. It pronounces the historicity of humanity and its binding to tradition.
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.
Social technology is a way of using human, intellectual and digital resources in order to influence social processes. For example, one might use social technology to ease social procedures via social software and social hardware, which might include the use of computers and information technology for governmental procedures or business practices. It has historically referred to two meanings: as a term related to social engineering, a meaning that began in the 19th century, and as a description of social software, a meaning that began in the early 21st century. Social technology is also split between human-oriented technologies and artifact-oriented technologies.
Historical materialism is Karl Marx's theory of history. Marx located historical change in the rise of class societies and the way humans labor together to make their livelihoods.
The Counter-Revolution of Science: Studies on the Abuse of Reason is a 1952 book by Nobel laureate economist Friedrich Hayek. In it Hayek condemns the positivist view of the social sciences for what he sees as scientism, arguing that attempts to apply the methods of natural science to the study of social institutions necessarily overlook the dispersed knowledge of the individuals which compose those institutions.
The Kuhn-Popper debate was a debate surrounding research methods and the advancement of scientific knowledge. In 1965, at the University of London's International Colloquium in the Philosophy of Science, Thomas Kuhn and Karl Popper engaged in a debate that circled around three main areas of disagreement. These areas included the concept of a scientific method, the specific behaviors and practices of scientists, and the differentiation between scientific knowledge and other forms of knowledge.
