"For it's well known that Bodies act upon one another

众所周知物体之间通过重力磁力
by the Attractions of Gravity, Magnetism and Electricity;

和电力的吸引相互作用
and these Instances shew the Tenor and Course of Nature,

这些事例显示了自然的状态与进程
and make it not improbable

也使我们相信
but that there may be more attractive Powers than these.

自然中也许存在更多吸引力
For Nature is very consonant and conformable to her self.

因为自然本身是怡然和谐的
How these Attractions may be perform'd, I do not here consider.

故我对这些引力是如何产生毫不在意
What I call Attraction may be perform'd by impulse--"

我所说的引力或许来自于冲力
Where did he get that idea?

他这个想法从哪儿来呢
Where did he get the idea that there are impulses

他怎么会有引力是来自于冲力
that can cause attraction?

这个想法呢
That was Descartes' idea, that we just explained.

我们刚刚讲过这是笛卡尔的想法
