I know that most men, including those at ease with problems of the greatest complexity, can seldom accept even the simplest and most obvious truth if it be such as would oblige them to admit the falsity of conclusions which they have delighted in explaining to colleagues, which they have proudly taught to others, and which they have woven, thread by thread, into the fabric of their lives.
Use truth as your anvil, nonviolence as your hammer and anything that does not stand the test when it is brought to the anvil of truth and hammered with nonviolence, reject it.
There is nothing more necessary than truth, and in comparison with it everything else has only secondary value. This absolute will to truth: what is it? Is it the will to not allow ourselves to be deceived? Is it the will not to deceive? One does not want to be deceived, under the supposition that it is injurious, dangerous, or fatal to be deceived.
There is no well defined boundary line between honesty and dishonesty. The frontiers of one blend with the outside limits of the other, and he who attempts to tread this dangerous ground may be sometimes in the one domain and sometimes in the other.
We cannot afford to differ on the question of honesty if we expect our republic permanently to endure. Honesty is not so much a credit as an absolute prerequisite to efficient service to the public. Unless a man is honest, we have no right to keep him in public life; it matters not how brilliant his capacity.
Oh, how great is the power of truth! which of its own power can easily defend itself against all the ingenuity and cunning and wisdom of men, and against the treacherous plots of all the world.
The life of a thinking man will probably be divided into two parts -- the first in which he desires to exterminate modern thinkers, and the second in which he desires to watch them exterminating each other. ... Suppose, for instance, there is an old story and a new skeptic who is skeptical of the story. We have only to wait a little while for a yet newer skeptic who is skeptical of the skeptic. He will probably find the old notion actually a help in his new notion. This process is an abstract truth applying to anything, apart from agreement or disagreement.
