Uncertainty(Related Subjects: Doubt)

Not to be absolutely certain is, I think, one of the essential things in rationality. Bertrand Russell (1872 - 1970), "Am I An Atheist Or An Agnostic?", 1947 When one admits that nothing is certain one must, I think, also admit that some things are much more nearly certain than others. Bertrand Russell (1872 - 1970), "Am I An Atheist Or An Agnostic?", 1947 I believe that uncertainty is really my spirit's way of whispering, "I'm in flux. I can't decide for you. Something is off-balance here." Oprah Winfrey (1954 - ), O Magazine, June 2003 In these matters the only certainty is that nothing is certain. Pliny the Elder (23 AD - 79 AD) The only thing that makes life possible is permanent, intolerable uncertainty; not knowing what comes next. Ursula K. LeGuin Doubt is not a pleasant condition, but certainty is absurd. Voltaire (1694 - 1778)
