3 ideas

2. Reason / A. Nature of Reason / 9. Limits of Reason
A foolish consistency is the hobgoblin of little minds [Emerson]
     Full Idea: A foolish consistency is the hobgoblin of little minds, adored by little statesmen and philosophers and divines. With consistency a great soul has simply nothing to do.
     From: Ralph Waldo Emerson (Self-Reliance [1841], p.37)
     A reaction: A remark to warm the hearts of pragmatists, Wittgensteinians, Nietzscheans and the post-modern mob. But pay careful attention to the word "foolish". Robert Fogelin gives a very balanced view of the matter (e.g. Idea 6557).
6. Mathematics / B. Foundations for Mathematics / 3. Axioms for Geometry
Archimedes defined a straight line as the shortest distance between two points [Archimedes, by Leibniz]
     Full Idea: Archimedes gave a sort of definition of 'straight line' when he said it is the shortest line between two points.
     From: report of Archimedes (fragments/reports [c.240 BCE]) by Gottfried Leibniz - New Essays on Human Understanding 4.13
     A reaction: Commentators observe that this reduces the purity of the original Euclidean axioms, because it involves distance and measurement, which are absent from the purest geometry.
25. Social Practice / C. Rights / 4. Property rights
Property is theft! [Proudhon]
     Full Idea: Property is theft!
     From: Pierre-Joseph Proudhon (What is Property? [1840]), quoted by Jonathan Wolff - An Introduction to Political Philosophy (Rev)
     A reaction: [Context in Proudhon's book?] This may not be the essence of property rights today, but it is almost undeniable as a historical fact. William the Conqueror kills the opposition in battle, and then gives English land to his friends.
