Instead of complaining about the darkness, light a candle.

States are inherently aggressive and expansionist because they exist in an anarchic international system where there is no higher authority to keep them in check.

真正的问题不在于机器是否会思考，而在于人类是否会思考。

——《没有门的大门》

必须有出世者的宽广胸怀，才能入世；否则的话，很容易受到尘世的各种利诱纠缠而使自己迅速堕落；必须有入世者的深刻体验，才能出世；否则的话，很容易变得空虚无聊而使自己难以把持人生。
