Explanatory Power
Explanatory power is the ability of a hypothesis or theory to explain the subject matter effectively to which it pertains. Its opposite is ''explanatory impotence''. In the past, various criteria or measures for explanatory power have been proposed. In particular, one hypothesis, theory, or explanation can be said to have more explanatory power than another about the same subject matter * If more facts or observations are accounted for; * If it changes more "surprising facts" into "a matter of course" (following Peirce); * If more details of causal relations are provided, leading to a high accuracy and precision of the description; * If it offers greater predictive power (if it offers more details about what should be expected to be seen and not seen); * If it depends less on authorities and more on observations; * If it makes fewer assumptions; * If it is more falsifiable (more testable by observation or experiment, according to Popper). * If it can be used to compress encod ...

Hypothesis
A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. Even though the words "hypothesis" and "theory" are often used interchangeably, a scientific hypothesis is not the same as a scientific theory. A working hypothesis is a provisionally accepted hypothesis proposed for further research in a process beginning with an educated guess or thought. A different meaning of the term ''hypothesis'' is used in formal logic, to denote the antecedent of a proposition; thus in the proposition "If ''P'', then ''Q''", ''P'' denotes the hypothesis (or antecedent); ''Q'' can be called a consequent. ''P'' is the assumption in a (possibly counterfactual) ''What If'' question. The adjective ''hypothetical'', meaning "hav ...

Demeter
In ancient Greek religion and mythology, Demeter (; Attic: ''Dēmḗtēr'' ; Doric: ''Dāmā́tēr'') is the Olympian goddess of the harvest and agriculture, presiding over crops, grains, food, and the fertility of the earth. Although she is mostly known as a grain goddess, she also appeared as a goddess of health, birth, and marriage, and had connections to the Greek Underworld, Underworld. She is also called Deo (). In Greek tradition, Demeter is the second child of the Titans Rhea (mythology), Rhea and Cronus, and sister to Hestia, Hera, Hades, Poseidon, and Zeus. Like her other siblings but Zeus, she was swallowed by her father as an infant and rescued by Zeus. Through her brother Zeus, she became the mother of Persephone, a fertility goddess. One of the most notable Homeric Hymns, the ''Homeric Hymn to Demeter'', tells the story of Persephone's abduction by Hades and Demeter's search for her. When Hades, the King of the Underworld, wished to make Persephone his wife ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Critical Rationalism
Critical rationalism is an epistemological philosophy advanced by Karl Popper on the basis that, if a statement cannot be logically deduced (from what is known), 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. In other words if we cannot assert it logically, we should at the least try to logically falsify it, which led Popper to his falsifiability criterion. Popper wrote about critical rationalism in many works, including: ''The Logic of Scientific Discovery'' (1934/1959), ''The Open Society and its Enemies'' (1945), ''Conjectures and Refutations'' (1963), '' Unended Quest'' (1976), and ''The Myth of the Framework'' (1994). Criticism, not support Critical rationalists hold that scientific theories and any other claims to knowledge can and should be rationally criticized, and (if they have empirical content) can and should be ...

Razor (philosophy)
In philosophy, a razor is a principle or rule of thumb that allows one to eliminate ("shave off") unlikely explanations for a phenomenon, or avoid unnecessary actions. Razors include: *Occam's razor: Simpler explanations are more likely to be correct; avoid unnecessary or improbable assumptions. * Hanlon's razor: Never attribute to malice that which can be adequately explained by stupidity. *Hitchens's razor: That which can be asserted without evidence can be dismissed without evidence. * Hume's guillotine: What ought to be cannot be deduced from what is. "If the cause, assigned for any effect, be not sufficient to produce it, we must either reject that cause, or add to it such qualities as will give it a just proportion to the effect." * Alder's razor (also known as Newton's Flaming Laser Sword): If something cannot be settled by experiment or observation, then it is not worthy of debate. : Also available as *Sagan standard: Extraordinary claims require extraordinary evidence. * P ...

Falsifiability
Falsifiability is a standard of evaluation of scientific theories and hypotheses that was introduced by the philosopher of science Karl Popper in his book ''The Logic of Scientific Discovery'' (1934). He proposed it as the cornerstone of a solution to both the problem of induction and the problem of demarcation. A theory or hypothesis is falsifiable (or refutable) if it can be ''logically'' contradicted by an empirical test that can potentially be executed with existing technologies. Popper insisted that, as a logical criterion, it is distinct from the related concept "capacity to be proven wrong" discussed in Lakatos' falsificationism. Even being a logical criterion, its purpose is to make the theory predictive and testable, thus useful in practice. Popper opposed falsifiability to the intuitively similar concept of verifiability. Verifying the claim "All swans are white" would theoretically require observing all swans, which in actuality, is not possible. In contrast, obs ...
