Happily, that question isn't so bad

幸运的是这个问题并不是很困难
because when we get to the story of the Spartans,

因为当我们讲到斯巴达那部分时
which comes after our story of the tyrants,

也就是僭主时期之后
I will read to you some of the poetry

我会给你们朗诵一些诗篇
which was the material with which Spartans were trained,

内容便是斯巴达军队的训练方式
and you'll quickly see why the Greek ethos,

然后你们就会明白古希腊民族精神
the Greek feeling of absolute commitment,voluntary absolute commitment,

那种绝对的责任感发自真心的责任感
even at the risk of your life for the polis

那种为了城邦牺牲也在所不辞的精神
was the central most important force in society.

就是斯巴达社会的核心价值
So, the answer is essentially a moral commitment,

所以这个问题的关键就在于
based upon training and belief.

建立在信念和训练上的道德责任感
This is why the Greeks did the phalanx,

这就是古希腊人能成功驾驭方阵的原因
