The Story of Philosophy《哲学的故事》第1章Plato第4节IV. The Ethical Problem第6段第7句：

How does Socrates — i.e., Plato — meet the challenge of this theory? At first he does not meet it at all. He points out that justice is a relation among individuals, depending on social organization; and that in consequence it can be studied better as part of the structure of a community than as a quality of personal conduct. If, he suggests, we can picture a just state, we shall be in a better position to describe a just individual. Plato excuses himself for this digression on the score that in testing a man's vision we make him read first large type, then smaller; so he argues, it is easier to analyze justice on a large scale than on the small scale of individual behavior. But we need not be deceived: in truth the Master is patching two books together, and uses the argument as a seam. He wishes not only to discuss the problems of personal morality, but the problems of social and political reconstruction as well. He has a Utopia up his sleeve, and is resolved to produce it. It is easy to forgive him, for the digression forms the core and value of his book.
浙江大学译本：他希望借此讨论的不仅仅是个人道德的种种问题，同时还有社会和政治改革的诸多话题。

解析

1、He wishes not only to discuss the problems of personal morality, but the problems of social and political reconstruction as well.
他不仅希望探讨个人道德问题，还希望探讨社会与政治重建问题。
not only...but...as well：并列结构，表示“不仅……而且……”，可以替代“not only…but also…”。

这句点出来了柏拉图就正义论题引出的探讨涉及了个人道德问题及其更高层面的社会与政治问题。
