  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. Northrop Frye:

    It is clear that all verbal structures with meaning are verbal imitations of that elusive psychological and physiological process known as thought, a process stumbling through emotional entanglements, sudden irrational convictions, involuntary gleams of insight, rationalized prejudices, and blocks of panic and inertia, finally to reach a completely incommunicable intuition.

  2. Jony Luna:

    We are just defending democracy, we are not crazy, or irrational, as they call us. Our fathers fought when they couldn't even read and write, now it is our time to fight, to defend our people and the people of Bolivia.

  3. Foreign Ministry spokeswoman Hua Chunying:

    We express dissatisfaction and opposition towards the U.S. side's report's irrational exaggerations of China's threat, we have already clearly explained our stance on the issue of construction on islands and reefs in the South China Sea several times.

  4. Auguste Comte, Philosophie Positive (1830):

    Every attempt to employ mathematical methods in the study of chemical questions must be considered profoundly irrational and contrary to the spirit of chemistry... If mathematical analysis should ever had prominent place in chemistry - an aberration, which is happily almost impossible - it would be a rapid and widespread degeneration of that science.

  5. 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.
