13007 | Archimedes defined a straight line as the shortest distance between two points [Archimedes, by Leibniz] |
Full Idea: Archimedes gave a sort of definition of 'straight line' when he said it is the shortest line between two points. | |
From: report of Archimedes (fragments/reports [c.240 BCE]) by Gottfried Leibniz - New Essays on Human Understanding 4.13 | |
A reaction: Commentators observe that this reduces the purity of the original Euclidean axioms, because it involves distance and measurement, which are absent from the purest geometry. |
20890 | Why do sexual relationships need permanence, if other relationships don't? [Punzo] |
Full Idea: What is the reason for demanding permanence in the relationship of sexual partners when we do not see such permanence as being importance to other human relationships? | |
From: Vincent C. Punzo (Morality and Human Sexuality [1969], p.220) | |
A reaction: The distinction may not be that simple. 'Loyalty' must certainly be mentioned. Friends can legitimately drift apart, but to desert a close friend at a time of great need might be as great a crime as adultery. When is loyalty particularly needed? |
20891 | Does engaging in sexual intercourse really need no more thought than playing tennis? [Punzo] |
Full Idea: It seems strange for a man and a woman to give no more thought to the question of whether they should engage in sexual intercourse than to the question of whether they shoud play tennis. | |
From: Vincent C. Punzo (Morality and Human Sexuality [1969], p.221) | |
A reaction: This strikes me as a reasonable point, but times have moved on since 1969, and for plenty of people nowadays playing tennis is a bigger issue than having sex, because of the time, equipment and effort involved. |
1868 | The world was made as much for animals as for man [Celsus] |
Full Idea: The world was made as much for the irrational animals as for men. | |
From: Celsus (On the True Doctrine (Against Christians) [c.178], §V) | |
A reaction: A good remark. It seems to be a classic distortion of European Christianity that the world is made for us, and that animals only exist to fill our sandwiches. |
1867 | Christians presented Jesus as a new kind of logos to oppose that of the philosophers [Celsus] |
Full Idea: Christians put forth this Jesus not only as the son of God, but as the very Logos - not the pure and holy Logos known to the philosophers, but a new kind of Logos. | |
From: Celsus (On the True Doctrine (Against Christians) [c.178], III) |
