Phaedo

Socrates himself has just been released from chains, and is led by this circumstance to make the natural remark that 'pleasure follows pain.'

苏格拉底刚刚被释放出锁链，这一情况使他自然地评论说：‘痛苦之后是快乐。’

Because several times in his life he had been warned in dreams that he should practise music; and as he was about to die and was not certain of what was meant, he wished to fulfil the admonition in the letter as well as in the spirit, by writing verses as well as by cultivating philosophy.

因为他一生中多次在梦中被警告应该练习音乐；当他即将死去并不确定这意味着什么时，他希望无论是在字面上还是精神上，都能遵从这一告诫，通过写诗和培养哲学来实现。
