Man can live and satisfy his wants only by ceaseless labor; by the ceaseless application of his faculties to natural resources. This process is the origin of property.
But it is also true that a man may live and satisfy his wants by seizing and consuming the products of the labor of others. This process is the origin of plunder.
It is impossible to introduce into society a greater change and a greater evil than this: the conversion of the law into an instrument of plunder.
