“At one time, many philosophers held that faultless "laws of thought" were somehow inherent, a priori, in the very nature of mind. This belief was twice shaken in the past century; first when Russell and his successors showed how the logic men employ can be defective, and later when Freud and Piaget started to reveal the tortuous ways in which our minds actually develop.” MenWayMindFirstsPastLawBeliefCenturyLogicPhilosopherOne TimeInherentSuccessorsDefective Author:Jean Piaget
“In [Aristotle's] formal logic, thought is organized in a manner very different from that of the Platonic dialogue. In this formal logic, thought is indifferent toward its objects. Whether they are mental or physical, whether they pertain to society or to nature, they become subject to the same general laws of organization, calculation, and conclusion - but they do so as fungible signs or symbols, in abstraction from their particular "substance." This general quality (quantitative quality) is the precondition of law and order - in logic as well as in society - the price of universal control.” WellsDifferentLawOrderQualitySubjectsObjectsParticularLogicOrganizationUniversalDialogueConclusionSymbolsSubstanceOrganizedIndifferentFormalAbstractionCalculationsLaw And OrderPlatonic Author:Herbert Marcuse
“Like music or art, mathematical equations can have a natural progression and logic that can evoke rare passions in a scientist. Although the lay public considers mathematical equations to be rather opaque, to a scientist an equation is very much like a movement in a larger symphony. Simplicity. Elegance. These are the qualities that have inspired some of the greatest artists to create their masterpieces, and they are precisely the same qualities that motivate scientists to search for the laws of nature. LIke a work of art or a haunting poem, equations have a beauty and rhythm all their own.” ArtLawArtistPassionNaturalQualityMovementLogicScientistLaysInspiredSimplicityRhythmMathematicalWorks Of ArtMasterpieceEquationsEleganceHauntingLaws Of NatureSymphonyProgressionEvokeOpaqueMathematical Equations Book:Hyperspace: A Scientific Odyssey through Parallel Universes, Time Warps, and the Tenth Dimension Source: Hyperspace: A Scientific Odyssey through Parallel Universes, Time Warps, and the Tenth Dimension

“The concept of absolute, hence (or whence) springs, in the moral field, the moral laws or norms, represent, in the field of knowledge, the principle of identity, which is the fundamental law of the thought; norms of logic springs from it, that govern the thought (or mind) in the field of science." ("Le concept de l'absolu, d'où découlent, dans le domaine moral, les lois ou normes morales, constitue, le principe d'identité, qui est la loi fondamentale de la pensée; il en découle les normes logiques qui régissent la pensée dans le domaine de la science.")” MindLawMoralPrinciplesFieldsIdentitySpringConceptsLogicAbsolutesFundamentalsPensNormMoraleMoral Law Author:African Spir
“The enthronement of Christ over the minds of men is steadily going forward. His kingdom embraces the princes in the realm of mind. It embraces the nations of highest civilization. They are all beneath the cross. It is maintained by simple authority. Other mental monarchs rule by logic; Christ's word is law--it is satisfying to His subjects. His truth in the hands of His disciples, like the bread He broke upon the mountains, is an ample supply for the millions that gather at His table.” MenMindHandsLawNationsChristSimpleMillionsSubjectsCivilizationMountainAuthorityHighestCrossesLogicTablesEmbraceKingdomsBreadBrokeRealmsSatisfyingDiscipleMonarchsBroke Up Author:Edward Thomson
