The Story of Philosophy的第117句：第1章Plato第2节II. Socrates第5段第2句：

There had been philosophers before him, of course: strong men like Thales and Heraclitus, subtle men like Parmenides and Zeno of Elea, seers like Pythagoras and Empedocles; but for the most part they had been physical philosophers; they had sought for the physics or nature of external things, the laws and constituents of the material and measurable world. That is very good, said Socrates; but there is an infinitely worthier subject for philosophers than all these trees and stones, and even all those stars; there is the mind of man. What is man, and what can he become?
浙江大学译本：苏格拉底说，这很好，然而对哲学家而言，还有远比花草树木、碎石繁星更具无限价值，研究对象一人的心灵。

解析

这句话强调苏格拉底对不同研究主题的地位作了区分，他认为对人的内心的研究远比对外在事物的研究更具有价值得多。
1、That is very good, said Socrates;
肯定以往的研究领域。肯定是为了突出后面的研究领域。

2、but there is an infinitely worthier subject for philosophers than all these trees and stones, and even all those stars;
一般研究主题：远所有这些树木、石头，甚至所有那些星星
All these与all those来囊括了所有外在的事物。
“infinitely”比very等程度强很多。

3、there is the mind of man.
更有价值：研究人的心灵。

“这个不错，”苏格拉底说，“但对于哲学家来说，有一个比所有这些树木、石头，甚至所有那些星星都要有价值得多的主题；那就是人的心灵。”
