| 13832 | Natural deduction shows the heart of reasoning (and sequent calculus is just a tool) [Gentzen, by Hacking] |
| Full Idea: Gentzen thought that his natural deduction gets at the heart of logical reasoning, and used the sequent calculus only as a convenient tool for proving his chief results. | |
| From: report of Gerhard Gentzen (Investigations into Logical Deduction [1935]) by Ian Hacking - What is Logic? §05 |
| 20558 | Your representative owes you his judgement, and betrays you if he gives your opinion instead [Burke] |
| Full Idea: Your representative owes you, not his industry only, but his judgement; and he betrays instead of serving you if he sacrifices it to your opinion | |
| From: Edmund Burke (Address to the Voters of Bristol [1774]), quoted by Adam Swift - Political Philosophy (3rd ed) | |
| A reaction: Nice rhetoric, but I'm not sure about the logic of it. Do I betray you if I give my stupid judgement rather than your wise one? Am I so arrogant as to think my judgement is always preferable? His audience was entirely of property owners. |
| 20523 | 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. |
