7 ideas

1. Philosophy / E. Nature of Metaphysics / 7. Against Metaphysics
14767 The demonstrations of the metaphysicians are all moonshine [Peirce]
     Full Idea: The demonstrations of the metaphysicians are all moonshine.
     From: Charles Sanders Peirce (Concerning the Author [1897], p.2)
1. Philosophy / G. Scientific Philosophy / 3. Scientism
14764 I am saturated with the spirit of physical science [Peirce]
     Full Idea: I am saturated, through and through, with the spirit of the physical sciences.
     From: Charles Sanders Peirce (Concerning the Author [1897], p.1)
4. Formal Logic / F. Set Theory ST / 4. Axioms for Sets / p. Axiom of Reducibility
21717 Reducibility undermines type ramification, and is committed to the existence of functions [Quine, by Linsky,B]
     Full Idea: Quine charges that the axiom of Reducibility both undoes the effect of the ramification, and commits the theory to a platonist view of propositional functions (which is a theory of sets, once use/mention confusions are cleared up).
     From: report of Willard Quine (Set Theory and its Logic [1963], p.249-58) by Bernard Linsky - Russell's Metaphysical Logic 6.1
11. Knowledge Aims / B. Certain Knowledge / 3. Fallibilism
14768 Infallibility in science is just a joke [Peirce]
     Full Idea: Infallibility in scientific matters seems to me irresistibly comical.
     From: Charles Sanders Peirce (Concerning the Author [1897], p.3)
12. Knowledge Sources / D. Empiricism / 2. Associationism
14765 Association of ideas is the best philosophical idea of the prescientific age [Peirce]
     Full Idea: The doctrine of the association of ideas is, to my thinking, the finest piece of philosophical work of the prescientific ages.
     From: Charles Sanders Peirce (Concerning the Author [1897], p.2)
14. Science / B. Scientific Theories / 1. Scientific Theory
14766 Duns Scotus offers perhaps the best logic and metaphysics for modern physical science [Peirce]
     Full Idea: The works of Duns Scotus have strongly influenced me. …His logic and metaphysics, torn away from its medievalism, …will go far toward supplying the philosophy which is best to harmonize with physical science.
     From: Charles Sanders Peirce (Concerning the Author [1897], p.2)
15. Nature of Minds / A. Nature of Mind / 2. Psuche
5959 Some philosophers say the soul is light [Plutarch]
     Full Idea: Some philosophers hold that the soul is in its essence light.
     From: Plutarch (75: Is 'Live Unknown' a Wise Precept? [c.85], §6)
     A reaction: A nice idea, to rival the stoic view that the soul is fire. It is understandable to propose that the soul is some sort of lightweight and fast moving matter. How else could thought be achieved physically? Nowadays, parallel processing is our only model.
