  1. irrational

    That is absurd which is contrary to the first principles of reasoning; as, that a part should be greater than the whole is absurd. A paradoxical statement appears at first thought contradictory or absurd, while it may be really true. Anything is irrational when clearly contrary to sound reason, foolish when contrary to practical good sense, silly when petty and contemptible in its folly, erroneous when containing error that vitiates the result, unreasonable when there seems a perverse bias or an intent to go wrong. Monstrous and preposterous refer to what is overwhelmingly absurd; as, "O monstrous! eleven buckram men grown out of two," Shakespeare 1 King Henry IV, act ii, sc. 4. The ridiculous or the nonsensical is worthy only to be laughed at. The lunatic's claim to be a king is ridiculous; the Mother Goose rimes are nonsensical. Compare INCONGRUOUS.

How to use irrational in a sentence?

  1. Dr. Thomas Arnold Mindell:

    The more I work with the body, keeping my assumptions in a temporary state of reservation, the more I appreciate and sympathize with a given "disease." The body no longer appears as a sick or irrational demon, but as a process with its own inner logic and wisdom.

  2. Justice Louis Brandeis:

    It is the function of speech to free men from the bondage of irrational fears.

  3. Ben Carson:

    It's OK to disagree with people, but it's not OK to destroy them, people are so frightened of the politically correct police that they are willing to do things that are irrational in order to appease them. I believe it's going to be necessary for those people who truly believe in our system, who believe in our Constitution, who believe in our principles and values that made America great, to be willing to stand up.

  4. Thiruman Archunan:

    Nature never allows man to understand it, however intelligent he thinks he may be. It tempts his reason by offering an initial success only to seduce and pull him on its side later, once for all. Finally, a man is left to sing the irrational songs of the nature!

  5. Guillermo Delgado:

    It is a victory for Cuba because it was achieved without conceding basic principles, for Obama, I think it's a spectacular step. ... All countries should change this irrational policy.
