Okay. Let's not go on talking about astronomical matters, but setting our sights down on earth, down on our human world. Unlike any other microscopic achievement we human enjoy bragging about, we are seldom aware of our often spectacular and sometimes even colorful ability to come up with some of the most ridiculous man-made ideas, and of course, our resolution to kill ourselves by the order of them. Those ideas include: rights, liberty, equality, democracy, patriotism, theism, capitalism, socialism and pretty much every -ism.

　　行了，是时间打住那些什么宇宙，什么星体，什么轨道之类的高谈阔论了，快把视线转回到地球，转回到我们人类社会。人类尤其喜爱夸耀我们那些事实上并不很重要的各种成就，却冷落了我们横溢着的制造各种诡异人工概念的才华。更低估了我们高举这些概念自相残杀的勇气和决心。这些人造的概念包括：权利、自由、平等、民主、宗教、爱国主义、资本主义、社会主义等等几乎所有主义。

While I agree that the general use of the word "freedom" is mostly accurate, it should be noted that freedom describes the state of being liberated from restraints, not escaped from all of them. And every freedom comes with a price. It's virtually impossible to give freedom here and not take away freedom there, as the conservation of freedom is just as inescapable as the conservation of mass and energy. One example, by giving drivers more freedom to speed their vehicles in downtown, we're compromising some of our pedestrians' freedom of walk the street without been struck by an speeding vehicle.

　　虽然我们平常使用“自由”一词通常是得当的。但我需要强调一下，自由一词意为从某些限制中解放出来，而非从所有限制中解放出来。任何一种形式的自由都会有其代价。你在此处提供自由的同时，必定会限制到彼处的自由。因为就像能量守恒和物质守恒一样，自由也是守恒的。举个例子：如果你给予市中心的司机高速行驶的自由，你同时就伤害到了市民徒步逛街而不被高速车辆伤害到的自由。

In general, humans are compulsively obsessed with controlling everything, so we conjure liberty out of thin air; We have little interest in acknowledging our differences and live with it, instead we made up an excuse dubbed equality; We hate to be forced or took advantages of, worry not, that's what rights were invented for; We don't want to be told, yet we demand to be heard, so we came up with this fantastic idea named democracy. Having the ability to vote makes us feel special, important, and most irresistibly, it makes us feel that we are in charge.

　　总体来讲，人类醉心于插手一切，所以我们凭空捏造出了一种概念叫“自由”；我们对了解彼此的不同并试着求同存异继续前进无甚兴趣，却制造出一个借口，取名为“平等”；我们讨厌被人摆布或利用，别担心，我们发明了一种好东西叫“权利”；我们不想被人说教，却总想说教别人，所以我们想出了一个很牛逼的名堂称为“民主”。拥有投票的权利，不但让我们感到与众不同、重要无比，更让我们欲罢不能的是，它让我们感觉到自己似乎手握乾坤。
