The Story of Philosophy的第73句：第1章Plato第1节The Context of Plato第5段第5句：

Traditions and dogmas rub one another down to a minimum in such centers of varied intercourse; where there are a thousand faiths we are apt to become skeptical of them all. Probably the traders were the first sceptic; they had seen too much to believe too much; and the general disposition of merchants to classify all men as either fools or knaves inclined them to question every creed. Gradually, too, they were developing science; mathematics grew with the increasing complexity of exchange, astronomy with the increasing audacity of navigation. The growth of wealth brought the leisure and security which are the prerequisite of research and speculation; men now asked the stars not only for guidance on the seas but as well for an answer to the riddles of the universe; the first Greek philosophers were astronomers. “Proud of their achievement,” says Aristotle, “men pushed farther afield after the Persian wars; they took all knowledge for their province, and sought ever wider studies.” Men grew bold enough to attempt natural explanations of processes and events before attributed to supernatural agencies and powers; magic and ritual slowly gave way to science and control; and philosophy began.
浙江大学版本：对此，亚里士多德曾说：“波斯战争之后，人们为自己的成就感到骄傲，并在探索的道路上愈行愈远；他们以一切现有的知识为基础开展研究，不断开拓出新的学术领域。”

解析

这句引用亚里士多德的话，表示人们在取得成就后的探索精神：知识及研究探索越来越远，越来越宽。
1、“Proud of their achievement,” says Aristotle,：
自豪感：出于对他们已经取得成就的自豪感。proud of their achievement属于形容词短语作原因状语。

2、 men pushed farther afield after the Persian wars;：
推进更远：希波战后，人类把视野和探索都推进到更远。
afield：away from home : away from here or there更远
— used with far, farther, or further
I must admit that this brings us far afield from our discussion of evolution.我必须承认，这距离我们讨论的演化，远得不沾边儿了。

3、they took all knowledge for their province,：
知识领域：他们不再局限传统的知识，而是把所有知识作为其研究领域。
province：这里熟词生义，指“a subject or area of interest that a person knows about or is involved in”，即“领域”。
It is a question of hydraulics, you see, and came within my own province.您瞧，这是一项水利学问题，属于我自己的专业知识范围之内的。

4、** and sought ever wider studies.**：
更广研究：人们不断追求更宽泛的学习研究。这里的“ever”用来修饰比较级，表示强调。

亚里士多德曾说过：“出于对已经取得成就的自豪感，战后人们推进更远，把所有的知识视为自己的研究领域并寻求更宽泛的研究。
