The Story of Philosophy的第91句：第1章Plato第1节The Context of Plato第8段第4句：

During the great generation-long Peloponnesian war(430-400 B.C.), in which the military power of Sparta fought and at last defeated the naval power of Athens, the Athenian oligarchic party, led by Critias, advocated the abandonment of democracy on the score of its inefficiency in war, and secretly lauded the aristocratic government of Sparta. Many of the oligarchic leaders were exiled: but when at last Athens surrendered, one of the peace conditions imposed by Sparta was the recall of these exiled aristocrats. They had hardly returned when, with Critias at their head, they declared a rich man’s revolution against the “democratic” party that had ruled during the disastrous war. The revolution failed, and Critias was killed on the field of battle.

革命失败了，克里提亚斯战死沙场。

整段

这段用雅典寡头政党来写雅典的动乱，外有与斯巴达的伯罗奔尼撒战争，内有寡头政党的异类政党的搅局。总之一个字，不太平。

雅典不太平

在长达近30年的伯罗奔尼撒战争（公元前430-公元前400年），斯巴达的军事力量对战并最终战胜了雅典的海军力量。在这期间，由克里提亚斯领导的雅典寡头政党由于民主制在战争中的低效，主张废弃它并暗地里对斯巴达的贵族制政府表示嘉许。许多寡头领袖都曾遭到流放，但在雅典投降时，在斯巴达施加的和平条件中，其中有一条就是召回所有被流放的贵族。他们一回来，由克里提亚斯带头发动了一场富人革命，以反对这场糟糕的战争中执政的“民主”党。革命失败了，克里提亚斯在战场中阵亡了。
