4. Formal Logic / F. Set Theory ST / 3. Types of Set / b. Empty (Null) Set
21548 The null class is the class with all the non-existents as its members [MacColl, by Lackey]
     Full Idea: In 1905 the Scottish logician Hugh MacColl published a paper in which he argued that the null class in logic should be taken as the class with all the non-existents as its members.
     From: report of Hugh MacColl (Symbolic Reasoning [1905]) by Douglas Lackey - Intros to Russell's 'Essays in Analysis' p.95
     A reaction: For the null object (zero) Frege just chose one sample concept with an empty extension. MacColl's set seems to have a lot of members, given that it is 'null'. How many, I wonder? Russell responded to this paper.
24. Political Theory / D. Ideologies / 5. Democracy / a. Nature of democracy
21131 Democracy is competition for support of the people, guided by self-interest on all sides [Posner]
     Full Idea: Democratic politics is a competition among self-interested politicians, constituting a ruling class, for the support of the people, also assumed to be self-interested, and none too interested or well informed about politics.
     From: Richard Posner (Law, Pragmatism and Democracy [2003], p.144), quoted by Andrew Shorten - Contemporary Political Theory 05
     A reaction: This articulates the 'competitive' view of democracy, as simply a technique for establishing legitimacy. Posner is also an economist, and they also assume that everyone is wholly self-interested, which may be why they are so frequently wrong.
29. Religion / B. Monotheistic Religion / 4. Christianity / d. Heresy
16713 Philosophers are the forefathers of heretics [Tertullian]
     Full Idea: Philosophers are the forefathers of heretics.
     From: Tertullian (works [c.200]), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 20.2
29. Religion / D. Religious Issues / 1. Religious Commitment / e. Fideism
6610 I believe because it is absurd [Tertullian]
     Full Idea: I believe because it is absurd ('Credo quia absurdum est').
     From: Tertullian (works [c.200]), quoted by Robert Fogelin - Walking the Tightrope of Reason n4.2
     A reaction: This seems to be a rather desperate remark, in response to what must have been rather good hostile arguments. No one would abandon the support of reason if it was easy to acquire. You can't deny its engaging romantic defiance, though.
