What did the ancient Greeks know about their world?不是翻译

Every Ancient Greece philosopher has built a quite complicated theory,each one of which contains much knowledge of the world.Here,I would like to take a most famous figures as sample.His name is Thales,the first recorded philosopher in history.
Thales was born in the city-state of Miletus,visited Egypt to study religion in his early year.Thales thinks the basic material that shapes the world is water.Modern researchers believe,this theoretical hypothesis origins from his learning experience in Egypt.As is known to all,the Nile nurtures the people of Egypt for centuries and centuries,but sometime it also brings disaster to this area,flooding thousands acres of land,and killing thousands of innocent folks.As a consequence,the Egyptian culture takes focus on how to deal with furious water,thinks the God of water (whose name sounds like "nu") to be the father of other gods.Thales accepted this view of the world from pure rational aspect,leaving a famous saying:"Everything comes from water,and returns to water."
工作好久,对英语都不熟悉了,写了半天.其实我原来是哲学系的,对这个问题倒是熟悉,但表达能力有点差TAT||,本来还想写赫拉克利特和德谟克利特的,但是这个英语水平还是算了吧
楼主自己查查,赫拉克利特是“火本原说”的代表,认为“世界是一团永恒的活火”；德谟克利特是开启近代科学的“原子说”的代表
泰勒斯、赫拉克利特、德谟克利特基本上展现了希腊自然哲学由原始走向成熟的道路,楼主有兴趣可以拿哲学史来读读~^^
