If one can go north, one can turn around and head south

(如果一个人能往北走，他就能掉头往南走)

equally, if one can go forward in imaginary time

(如果一个人能在虚的时间里向前走）

one ought to be able to turn round and go backward

（他就能转过来往后走)

This means that there can be no important difference between theforward and backward directions of imaginary time

（在虚时间里，往前和往后并不存在重要的差别）

On the other hand, when one looks at"real" time

（但当人们考察时间时）

there's a very big difference between the forward and backwarddirections

（ 在时间里前进或后退存在着巨大差别）

as we all know. Where does this difference between the past and thefuture come from?

（过去和将来之间这种差别从何而来？）

Why do we remember the past but not the future?

（为什么我们记住的是过去而不是未来？）
