9 ideas
| 9271 | Human knowledge may not produce well-being; the examined life may not be worth living [Gray] |
| Full Idea: Human knowledge is one thing, human well-being another. There is no predetermined harmony between the two. The examined life may not be worth living. | |
| From: John Gray (Straw Dogs [2002], 1.9) | |
| A reaction: John Gray has set himself up as the Eeyore of modern times, but this point may obviously be correct. Presumably Socrates meant that the examined life was better even if the result was less 'well-being'. Even Gray doesn't want a lobotomy. |
| 19347 | Substance needs independence, unity, and stability (for individuation); also it is a subject, for predicates [Perkins] |
| Full Idea: For individuation, substance needs three properties: independence, to separate it from other things; unity, to call it one thing, rather than an aggregate; and permanence or stability over time. Its other role is as subject for predicates. | |
| From: Franklin Perkins (Leibniz: Guide for the Perplexed [2007], 3.1) | |
| A reaction: Perkins is describing the Aristotelian view, which is taken up by Leibniz. 'Substance' is not a controversial idea, if we see that it only means that the world is full of 'things'. It is an unusual philosopher wholly totally denies that. |
| 9275 | Knowledge does not need minds or nervous systems; it is found in all living things [Gray] |
| Full Idea: Knowledge does not need minds, or even nervous systems. It is found in all living things. | |
| From: John Gray (Straw Dogs [2002], 2.10) | |
| A reaction: I consider it a misnomer to call such things 'knowledge', for which I have much higher standards. Gray is talking about 'information'. Knowledge needs reasons, and possibility of error, not just anticipatory behaviour. |
| 9276 | The will hardly ever does anything; most of our life just happens to us [Gray] |
| Full Idea: We think our actions express our decisions, but in nearly all of our life, willing decides nothing. We cannot wake up or fall asleep, remember or forget our dreams, summon or banish our thoughts, by deciding to do so. | |
| From: John Gray (Straw Dogs [2002], 2.12) | |
| A reaction: Gray's point does not rule out occasional total control over mental life, but his point is important. The traditional picture is of a life controlled, so the will is seen as at the centre of a person, but it just isn't the case. |
| 8693 | An 'abstraction principle' says two things are identical if they are 'equivalent' in some respect [Boolos] |
| Full Idea: Hume's Principle has a structure Boolos calls an 'abstraction principle'. Within the scope of two universal quantifiers, a biconditional connects an identity between two things and an equivalence relation. It says we don't care about other differences. | |
| From: George Boolos (Is Hume's Principle analytic? [1997]), quoted by Michèle Friend - Introducing the Philosophy of Mathematics 3.7 | |
| A reaction: This seems to be the traditional principle of abstraction by ignoring some properties, but dressed up in the clothes of formal logic. Frege tries to eliminate psychology, but Boolos implies that what we 'care about' is relevant. |
| 9278 | Nowadays we identify the free life with the good life [Gray] |
| Full Idea: We do not value freedom more than people did in earlier times, but we have identified the good life with the chosen life. | |
| From: John Gray (Straw Dogs [2002], 3.13) | |
| A reaction: Interesting. This is Enlightenment liberalism gradually filtering down into common consciousness, especially via the hegemony of American culture. I sympathise the Gray; don't get me wrong, but I think freedom is overrated. |
| 9280 | Over forty percent of the Earth's living tissue is human [Gray] |
| Full Idea: Humans co-opt over forty per cent of the Earth's living tissue. | |
| From: John Gray (Straw Dogs [2002], 4.15) | |
| A reaction: If you add our domestic animals, I understand that the figure goes up to 95 per cent! I take this to be virtually the only significant ecological fact - population, population, population. Why are there so many cars? So many carbon footprints? |
| 9272 | Without Christianity we lose the idea that human history has a meaning [Gray] |
| Full Idea: For Christians, it is because they occur in history that the lives of humans have a meaning that the lives of other animals do not. ..If we truly leave Christianity behind, we must give up the idea that human history has a meaning. | |
| From: John Gray (Straw Dogs [2002], 2.3) | |
| A reaction: Interesting. Compare the dispute between 'whig' and 'tory' historians, the former of whom believe that history is going somewhere. |
| 9279 | What was our original sin, and how could Christ's suffering redeem it? [Gray] |
| Full Idea: No one can say what was humankind's original sin, and no one understands how the suffering of Christ can redeem it. | |
| From: John Gray (Straw Dogs [2002], 4.1) | |
| A reaction: This nicely articulates a problem that has half bothered me, but I have never put into words. I always assumed Eve committed the sin, and Adam cops the blame for not controlling his woman. Dying for our sins has always puzzled me. |
