Kant has a more stringent demanding notion of what it means to be free.

康德对何谓自由有更加严苛的定义
And though it's stringent and demanding,

虽然很严格也很苛刻
if you think it through, it's actually pretty persuasive.

但仔细想就会发现它颇具说服力
Kant reasons as follows:

康德的推理如下
when we, like animals, seek after pleasure

当我们像动物一样寻求快乐
or the satisfaction of our desires or the avoidance of pain,

或满足欲望或逃避痛苦的时候
when we do that we aren't really acting freely.

我们做这些时并不是真正地在自由行动
Why not?

为什么不是呢
We're really acting as the slaves of those appetites and impulses.

我们实际上是那些欲望和冲动的奴隶
I didn't choose this particular hunger or that particular appetite

我并没有刻意地去选择某个欲望
and so when I act to satisfy it, i'm just acting according to natural necessity.

所以当我去满足它时仅仅是出于本能需要
And for Kant, freedom is the opposite of necessity.

而对于康德而言自由则是需要的对立面
