"If he will not tell the truth, except when it is for his interest to do so, let us make it for his interest to tell the truth. We can do it by applying to him the same principle of justice that we apply to ourselves... At this point I have one certain test. Mankind are not held together by lies. Trust is the foundation of society. Where there is no truth, there can be no trust, and where there is no trust, there can be no society. Where there is society, there is trust, and where there is trust, there is something upon which it is supported."
