Although a bundle of hypotheses (i.e. a hypothesis and its background assumptions) as a whole can be tested against the empirical world and be falsified if it fails the test, the Duhem–Quine thesis says it is impossible to isolate a single hypothesis in the bundle. One solution to the dilemma thus facing scientists is that when we have ...
Coherence theory of truth – Theory of truth based on coherence No true Scotsman – Informal logical fallacy Semantic holism – theory in the philosophy of language that a certain part of language (e.g. a term, a complete sentence) can only be understood through its relations to a (previously understood) larger segment of language Pages ...
The theory met critical objections to truth as correspondence and thereby rehabilitated it. The theory also seemed, in Popper's eyes, to support metaphysical realism and the regulative idea of a search for truth. According to this theory, the conditions for the truth of a sentence as well as the sentences themselves are part of a metalanguage ...
Since it is absurd to have no logical method for settling on one hypothesis amongst an infinite number of equally data-compliant hypotheses, we should choose the simplest theory: "Either science is irrational [in the way it judges theories and predictions probable] or the principle of simplicity is a fundamental synthetic a priori truth." [42]
The least probable theory is preferred because it is the one with the highest information content and most open to future falsification. Critical rationalism as a discourse positioned itself against what its proponents took to be epistemologically relativist philosophies, particularly post-modernist or sociological approaches to knowledge ...
A self-refuting idea or self-defeating idea is an idea or statement whose falsehood is a logical consequence of the act or situation of holding them to be true. Many ideas are called self-refuting by their detractors, and such accusations are therefore almost always controversial, with defenders stating that the idea is being misunderstood or that the argument is invalid.
Conspiracy-theory-entranced seniors have described to me how, before adopting a QAnon-like brand of what some called “activism,” they felt as if society no longer valued or had use for them.
Warburton says that one reason for the unreliability of the consensus theory of truth, is that people are gullible, easily misled, and prone to wishful thinking—they believe an assertion and espouse it as truth in the face of overwhelming evidence and facts to the contrary, simply because they wish that things were so.
