"Any road followed precisely to its end leads precisely nowhere. Climb the mountain just a little bit to test that it's a mountain. From the top of the mountain, you cannot see the mountain."
What is truth? We must adopt a pragmatic definition: it is what is believed
to be the truth. A lie that is put across therefore becomes the truth and
may, therefore, be justified. The difficulty is to keep up lying... it is
simpler to tell the truth and if a sufficient emergency arises, to tell one,
big thumping lie that will then be believed.
To announce that there must be no criticism of the President, or that we are to stand by the President, right or wrong, is not only unpatriotic and servile, but is morally treasonable to the American public. Nothing but the truth should be spoken about him or anyone else. But it is even more important to tell the truth, pleasant or unpleasant, about him than about any one else.
An invasion of armies can be resisted, but not an idea whose time has come.
