  4. Etymology: [OF. certainet.]


  1. Certainty

    Certainty is perfect knowledge that has total security from error, or the mental state of being without doubt. Objectively defined, certainty is total continuity and validity of all foundational inquiry, to the highest degree of precision. Something is certain only if no skepticism can occur. Philosophy seeks this state. It is widely held that certainty about the real world is a failed historical enterprise. This is in large part due to the power of David Hume's problem of induction. Physicist Carlo Rovelli adds that certainty, in real life, is useless or often damaging.

Examples of certainty in a Sentence

  1. Syngenta Chairman Michel Demare:

    A serious proposal to buy Syngenta has to be made at full and fair value, it has to recognize for shareholders the inherent combination benefits. And it has to provide a high degree of certainty that the transaction will be closed, including compensation in case the deal fails.

  2. Bertrand Russell:

    When one admits that nothing is certain one must, I think, also admit that some things are much more nearly certain than others. It is much more nearly certain that we are assembled here tonight than it is that this or that political party is in the right. Certainly there are degrees of certainty, and one should be very careful to emphasize that fact, because otherwise one is landed in an utter skepticism, and complete skepticism would, of course, be totally barren and completely useless.

  3. Gilroy Police Chief Scot Smithee:

    Our investigation is leading us more and more to believe that there was not a second person involved, i don't think I could say that with absolute certainty at this point because we're still following up leads.

  4. Jeff Masters:

    The atmosphere is fundamentally chaotic and unpredictable, there's a limit to how much certainty we can have in the modeling.

  5. Saint Augustine, Confessions:

    My love for you, Lord, is not an uncertain feeling, but a matter of concious certainty. With your word you pierced my heart, and I loved you. But heaven and earth and everything in them on all sides tell me to love you.
