12. Knowledge Sources / D. Empiricism / 3. Pragmatism
14794 Instead of seeking Truth, we should seek belief that is beyond doubt [Peirce]
     Full Idea: Your problems would be greatly simplified, if, instead of saying that you want to know the Truth, you were simply to say that you want to attain a state of belief unassailable beyond doubt.
     From: Charles Sanders Peirce (Essentials of Pragmatism [1905], I)
     A reaction: This is not the same as saying that belief beyond doubt IS truth. He is merely offering a strategy for scientists to side-step the sort of scepticism raised by Descartes and radical empiricists.
17. Mind and Body / E. Mind as Physical / 1. Physical Mind
23221 The brain, and all the mental events within it, consists entirely of sensitive and rational matter [Cavendish]
     Full Idea: Sensitive and rational matter …makes not only the Brain, but all Thoughts, Conceptions, Imaginations, Fancy, Understanding, Memory, Remembrance, and whatsoever motions are in the Head or Brain.
     From: Margaret Cavendish (Philosophical Letters [1664], p.185), quoted by Matthew Cobb - The Idea of the Brain 2
     A reaction: Judging by the date of this, and that she is a Cavendish, the influence of Hobbes must be strong, which was brave in 1664. A very strong statement of reductive physicalism, making sure that nothing is left out.
18. Thought / D. Concepts / 3. Ontology of Concepts / b. Concepts as abilities
14792 A 'conception', the rational implication of a word, lies in its bearing upon the conduct of life [Peirce]
     Full Idea: The present writer framed the theory that a 'conception', that is, the rational purport of a word or other expression, lies exclusively in its conceivable bearing upon the conduct of life.
     From: Charles Sanders Peirce (Essentials of Pragmatism [1905], I)
18. Thought / D. Concepts / 4. Structure of Concepts / b. Analysis of concepts
14793 The definition of a concept is just its experimental implications [Peirce]
     Full Idea: If one can define accurately all the conceivable experimental phenomena which the affirmation or denial of a concept could imply, one will have therein a complete definition of the concept, and there is absolutely nothing more in it.
     From: Charles Sanders Peirce (Essentials of Pragmatism [1905], I)
     A reaction: Strictly, I would have thought you could only affirm or deny a complete proposition, rather than a concept. What should I do with the concept of a 'unicorn'? Note that all theories, such as empiricism or pragmatism, begin with an account of our concepts.
26. Natural Theory / D. Laws of Nature / 11. Against Laws of Nature
15877 The aim of science is just to create a comprehensive, elegant language to describe brute facts [Poincaré, by Harré]
     Full Idea: In Poincaré's view, we try to construct a language within which the brute facts of experience are expressed as comprehensively and as elegantly as possible. The job of science is the forging of a language precisely suited to that purpose.
     From: report of Henri Poincaré (The Value of Science [1906], Pt III) by Rom Harré - Laws of Nature 2
     A reaction: I'm often struck by how obscure and difficult our accounts of self-evident facts can be. Chairs are easy, and the metaphysics of chairs is hideous. Why is that? I'm a robust realist, but I like Poincaré's idea. He permits facts.
