Rather than argue for the necessity of a god, some theists base their belief upon grounds independent of, or prior to, reason, making Occam's razor irrelevant. THE LAW OF PARSIMONY. Physicist R. V. Jones contrived Crabtree's Bludgeon, which states that "[n]o set of mutually inconsistent observations can exist for which some human intellect cannot conceive a coherent explanation, however complicated."[84]. Cladistic parsimony is used to select as the preferred hypothesis of relationships the cladogram that requires the fewest implied character state transformations (or smallest weight, if characters are differentially weighted). Occam's Razor - Learning Theories pic.twitter.com/fgaSyjY2Wf, YIMBY! Similarly, in science, Occam's razor is used as an abductive heuristic in the development of theoretical models rather than as a rigorous arbiter between candidate models. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree. Ad hoc hypotheses are justifications that prevent theories from being falsified. [5][6] In physics, parsimony was an important heuristic in Albert Einstein's formulation of special relativity,[46][47] in the development and application of the principle of least action by Pierre Louis Maupertuis and Leonhard Euler,[48] and in the development of quantum mechanics by Max Planck, Werner Heisenberg and Louis de Broglie. Paul Churchland (1984) states that by itself Occam's razor is inconclusive regarding duality. Statistical versions of Occam's razor have a more rigorous formulation than what philosophical discussions produce. "[63] Ockham believed that an explanation has no sufficient basis in reality when it does not harmonize with reason, experience, or the Bible. Also called economy principle; principle of economy; principle of parsimony. He cautions: "While Ockham's razor is a useful tool in the physical sciences, it can be a very dangerous implement in biology. (Morgan 1903). Morgan's Canon, also known as Lloyd Morgan's Canon, Morgan's Canon of Interpretation or the principle or law of parsimony, is a fundamental precept of comparative (animal) psychology, coined by 19th-century British psychologist C. Lloyd Morgan. By using parsimony psychology in therapy, therapists can ensure that everyone is on the same page and that the core ideas of a concept are being discussed and understood. Another way to say this is that the correct explanation or solution is usually the simplest.
