Common sense is the best distributed thing in the world, for everyone thinks he is so well-endowed with it that even those who are hardest to satisfy in all other matters are not in the habit of desiring more of it than they already have.
常识是世界上分布最广的东西，因为每个人都认为自己拥有丰富的常识，即使是那些在其他事情上最难满足的人，也没有比他们已经拥有的东西更渴望得到常识的习惯。
