The Story of Philosophy《哲学的故事》第1章Plato第7节VI. The Psychological Solution第6段第1句：

Plato passes on to a remarkable anticipation of "psychoanalysis." Our political psychology is perplexed, he argues, because we have not adequately studied the various appetites or instincts of man. Dreams may give us a clue to some of the subtle and more elusive of these dispositions.
浙江大学译本：接下来，柏拉图对“精神分析”进行了一次著名的预测。

解析

1、Plato passes on to a remarkable anticipation of "psychoanalysis."
他进而惊人地预见“精神分析”。
pass on to：本义指“传递，转交”，这里引申为思想脉络的“转向”。
psychoanalysis: a method of explaining and treating mental and emotional problems by having the patient talk about dreams , feelings, memories, etc.精神分析
这个词由psycho-与analysis组合而成，
Freud invented psychoanalysis and popularized many ideas like the ego, the unconscious, and talking to a therapist. 弗洛伊德发明了精神分析， 并普及了许多思想，如自我、无意识和与治疗师交谈《BBC Ideas精选》

这句从非理性过渡到了“精神分析”，只用了“pass on to”。难怪说柏拉图以后的哲学都能在柏拉图这找到根源，连弗洛伊德也不例外。
