Further, the typical locomotions of the elementary natural bodies-namely, fire, earth, and the like-show not only that place is something, but also that it exerts a certain influence. Each is carried to its own place, if it is not hindered, the one up, the other down. Now these are regions or kinds of place-up and down and the rest of the six directions. Nor do such distinctions (up and down and right and left, &c.) hold only in relation to us. To us they are not always the same but change with the direction in which we are turned: that is why the same thing may be both right and left, up and down, before and behind. But in nature each is distinct, taken apart by itself. It is not every chance direction which is 'up', but where fire and what is light are carried; similarly, too, 'down' is not any chance direction but where what has weight and what is made of earth are carried-the implication being that these places do not differ merely in relative position, but also as possessing distinct potencies.
謝謝二位,你們顯然都是各自領域裏的專家。Wish to hear a lot more from you both. "A brief history of time" is indeed very difficult to read and few people will enjoy reading it, but it does make it a bit easier to understand the concepts of space, time, and relativity. But let's not hasten to make a judgement on the book.
'無知無為',
I am enormously interested in why the 'TMD' (笑)Greek would be thinking about what the earth was and how the universal worked as a system, and Aristotle even discussed the concept of 'Time'. Space and Time? Come on! It would matter little, or not at all, if the earth was flat or square in those early days. What would cause them even to think about such things? Also the Euclid geometry was so perfect and correct that it still stands true after 2300 years. What caused them to study geometry to such a great depth, which was totally impractical, and absolutely useless, in those days. 能當飯吃啊?
I hope you understand why I am asking such questions, out of shear curiosity. As you said 有點二百五精神. 謝謝。

謝謝你的鼓勵。 我不再為自己是中國人自卑了。 剩下的最大自卑就隻有這個了。I know you are an Greek expert. Please help me in my struggle in seeking an answer to my question. It is really an academic exercise for me, no emotion attached, definitely not a national pride thing for me. Thank you. 謝謝

I am not yet able to comment on your view, which I think is incredibly interesting, and I truly wish you can write more about it. I will be the very first one to read it.
