10245 | One geometry cannot be more true than another [Poincaré] |
Full Idea: One geometry cannot be more true than another; it can only be more convenient. | |
From: Henri Poincaré (Science and Method [1908], p.65), quoted by Stewart Shapiro - Philosophy of Mathematics | |
A reaction: This is the culminating view after new geometries were developed by tinkering with Euclid's parallels postulate. |
16789 | Only supernatural means could annihilate anything once it had being [Hobbes] |
Full Idea: A being cannot naturally go out of existence. For even if a ship or a plank ceases to be a ship or a plank, it never naturally ceases to be a being. For a being, unless it is annihilated, does not cease to be a being. To annihilate is a supernatural task. | |
From: Thomas Hobbes (De Mundo (On the World) [1642], 12.5) | |
A reaction: This idea was becoming an orthodoxy in Hobbes's time, and leads to the various conservation laws in physics. |
4052 | It has become normal to consider passive euthanasia while condemning active euthanasia [Rachels] |
Full Idea: It seems to have become accepted that passive euthanasia (by withholding treatment and allowing a patient to die) may be acceptable, whereas active euthanasia (direct action to kill the patient) is never acceptable. | |
From: James Rachels (No Moral Difference [1975], p.97) | |
A reaction: He goes on to attack the distinction. It is hard to distinguish the two cases, as well as being hard to judge them. |
4053 | If it is desirable that a given patient die, then moral objections to killing them do not apply [Rachels] |
Full Idea: The cause of death (injection or disease) is important from the legal point of view, but not morally. If euthanasia is desirable in a given case then the patient's death is not an evil, so the usual objections to killing do not apply. | |
From: James Rachels (No Moral Difference [1975], p.102) | |
A reaction: Seems reasonable, but a very consequentialist view. Is it good that small children should clean public toilets? |
