Agnosticism simply means that a man shall not say he knows or believes that for which he has no grounds for professing to believe.

The foundation of all morality is to have done, once and for all, with lying; to give up pretending to believe that for which there is no evidence, and repeating unintelligible propositions about things beyond the possibilities of knowledge.

Various kinds of ideas can be classified by their relationship to the authentication process. There are ideas systematically prepared for authentication ("theories"), ideas not derived from any systematic process ("visions"), ideas which could not survive any reasonable authentication process ("illusions"), ideas which exempt themselves from any authentication process ("myths"), ideas which have already passed authentication processes ("facts"), as well as ideas known to have failed- or certain to fail- such processes ("falsehoods" - both mistakes and lies).

Beware of the man of one book.

Nothing as mundane as mere evidence can be allowed to threaten a vision so deeply satisfying.
