490 | Everything happens by reason and necessity [Leucippus] |
Full Idea: Nothing happens at random; everything happens out of reason and by necessity. | |
From: Leucippus (fragments/reports [c.435 BCE], B002), quoted by (who?) - where? |
3448 | Do new ideas increase the weight of the brain? [Dance] |
Full Idea: If someone gives you a piece of information, does your brain suddenly become heavier? | |
From: Adam Dance (works [2001]), quoted by PG - Db (ideas) | |
A reaction: A beautifully simple question, which is a reductio of the idea that information is simply a physical object. The question points to a functionalist account of brain activity. |
7293 | It is legitimate to do harm if it is the unintended side-effect of an effort to achieve a good [Grayling] |
Full Idea: The doctrine of double effect says that it is legitimate to do harm if the harm is the unintended side-effect of an effort to achieve a legitimate goal. | |
From: A.C. Grayling (Among the Dead Cities [2006], Ch.6) | |
A reaction: I think a key principle of morality is our duty to think about possible unnoticed consequences of our actions. To neglect concern for side-effects is wicked. Beyond that, the issue must concern the particulars of the situation. |
7292 | War must also have a good chance of success, and be waged with moderation [Grayling] |
Full Idea: To Aquinas's three conditions for war (Idea 7291) modern theorists have added two others: that to be just a war must have a reasonable chance of success, and that the means used to conduct it must be proportional to the ends sought. | |
From: A.C. Grayling (Among the Dead Cities [2006], Ch.6) | |
A reaction: These two principles strike me as being much more civilized and humane than Aquinas's original contribution, suggesting that in our theoretical thinking we might be making some progress. |
