Suppose that I am a laborer and you an iron-founder.
It would be a great advantage to me to buy hatchets cheap, and even to get them for nothing.

But, in the exercise of your legitimate right of self-defense, you at first resist force with force; afterwards, invoking the power of the law, the magistrate, and the constables, you throw me into prison--and you do well.
Oh! ho! the thought suggests itself to me that I have been very awkward in this business.

When a person wishes to enjoy the property of other people, he will, unless he is a fool, act _in accordance_ with the law, and not _in violation_ of it.
