Here is a statement of Gandhi that sums up clearly and concisely the whole doctrine of nonviolence: “The way of peace is the way of truth.” “Truthfulness is even more important than peacefulness. Indeed, lying is the mother of violence. A truthful man cannot long remain violent. He will perceive in the course of his research that he has no need to be violent, and he will further discover that so long as there is the slightest trace of violence in him, he will fail to find the truth he is searching.” Why can we not believe this immediately? Why do we doubt it? Why does it seem impossible? Simply because we are all, to some extent, liars.

We are living under a tyranny of untruth which confirms itself in power and establishes a more and more total control over men in proportion as they convince themselves they are resisting error.

Our submission to plausible and useful lies involves us in greater and more obvious contradictions, and to hide these from ourselves we need greater and ever less plausible lies. The basic falsehood is the lie that we are totally dedicated to truth, and that we can remain dedicated to truth in a manner that is at the same time honest and exclusive: that we have the monopoly of all truth, just as our adversary of the moment has the monopoly of all error.

We then convince ourselves that we cannot preserve our purity of vision and our inner sincerity if we enter into dialogue with the enemy, for he will corrupt us with his error. We believe, finally, that truth cannot be preserved except by the destruction of the enemy- for, since we have identified him with error, to destroy him is to destroy error. The adversary, of course, has exactly the same thoughts about us and exactly the same basic policy by which he defends the “truth.” He has identified us with dishoneity, and untruth. He believes that, if we are destroyed, nothing will be left but truth.
