1. foolish

   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.
