If we interpret these sentences given in the same Address, one by the other, it appears that this eminent philosopher felt in 1858 his confidence shaken that the Apteryx and the Red Grouse first appeared in their respective homes,"he knew not how," or by some process "he knew not what."

如果我们把同一演讲中这些词句逐一加以解释，看来这位著名学者在1858年对下述情况的信念已经发生了动摇，即他不知道无翅鸟和红松鸟怎样在它们各自的乡土上发生，也就是说，不知道它们的发生过程。

Once the agent learns each aspect of the mdel that isn't given. For instance, it might know its utility, but not what the world looks like, which might be the case for an explorer robot, or it might know the state of the world, but not the value of its actions, as might be the case if the agent were learning to play a game like backgammon.

例如，它了解它的效用，但不知道世界看起来像什么，这可能是勘查机器人遇到的一种情况，或者它了解世界的状态，但不知道它的行为会获得多少分值（分值的概念见上文，译者注），如果智能体在学习玩游戏，比如西洋双陆棋时同样也可能发生这种情况。

I assure you, I do not know.

我不知道，我想你们也不知道。

I have know idea what I should do ,seeing the words you write online ,thoroughly,it is an assuredness that you the girl that I have seeking and waiting for,and I don't know who is still the expcetion that can put the sorrows into the bottom of my heart besides you ,and that haven't the qulification for hurting mine.

那时我在网上看到一些专门针对我，并令我无法忍受的评论，我有撕心裂肺的感觉，感觉到痛苦到极点，这会伤害我一辈子！我不知道现在我该做什么。看着你在网上写的那些文字，我确信，你就是那个我一直寻找和等待的女孩。除了你，我不知道谁还能真正伤到我的心，谁还有资格伤害我！

At the very start, let me just say that we both have something in common.

演讲开始时我们有一些共同点，你们不知道我要讲什么——我也不知道。

The proportion of freedom to necessity is decreased or increased, according to the point of view from which the act is regarded; but there always remains an inverse ratio between them. A drowning man clutching at another and drowning him, or a hungry mother starved by suckling her baby and stealing food, or a man trained to discipline who at the word of command kills a defenceless man, all seem less guilty—that is, less free and more subject to the law of necessity to one who knows the circumstances in which they are placed, and more free to one who did not know that the man was himself drowning, that the mother was starving, that the soldier was on duty, and so on.

一个先足落水的人，抓住另一个人，那人也要淹死了；或者，一个因为哺育婴儿而疲惫不堪的、饥饿的母亲，偷了一些食物；或者，一个养成遵守纪律习惯的人，在服役期间，遵照长官命令，杀掉一个不能自卫的人——在知道那些人所处的条件的人看来，似乎罪过比较小，也就是自由比较小，属于必然性法则的成分比较多；而在不知道那个人自己就要淹死、那个母亲在挨饿、那个士兵在服役等等的人看来，自由就比较多。

I do not know, who knows, no one, because the truth is not attaching conditions truth.

我不知道，谁知道呢，没有人，因为附加条件的真理不是真理。

B : i don't know, i don't know....

我不知道，真的不知道。。。
