| 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. |
| 22474 | Unlike aesthetic evaluation, moral evaluation needs a concept of responsibility [Foot] |
| Full Idea: Moral, as opposed to aesthetic, evaluation does require some distinction between actions for which we are responsible and those for which we are not responsible. | |
| From: Philippa Foot (Nietzsche's Immoralism [1991], p.154) | |
| A reaction: It is hard to disagree with this, but difficult to give a precise account of responsibility, probably because it is not an all-or-nothing matter. If we accept responsibility for our controlled actions, why not for our considered aesthetic judgements? |
| 7903 | The six perfections are giving, morality, patience, vigour, meditation, and wisdom [Nagarjuna] |
| Full Idea: The six perfections are of giving, morality, patience, vigour, meditation, and wisdom. | |
| From: Nagarjuna (Mahaprajnaparamitashastra [c.120], 88) | |
| A reaction: What is 'morality', if giving is not part of it? I like patience and vigour being two of the virtues, which immediately implies an Aristotelian mean (which is always what is 'appropriate'). |
| 22472 | The practice of justice may well need a recognition of human equality [Foot] |
| Full Idea: I wonder whether the practice of justice may not absolutely require a certain recognition of equality between human beings, not a pretence of the equality of talents, but something deeper. | |
| From: Philippa Foot (Nietzsche's Immoralism [1991], p.152) | |
| A reaction: {My 'something deeper' is expressed by Foot in a quotation from Gertrude Stein]. This may well be the most fundamental division which runs across a society - between those who accept and those reject human equality. |
