English Synonyms and Antonyms

  1. rational

    Sagacious refers to a power of tracing the hidden or recondite by slight indications, as by instinct or intuition; it is not now applied to mere keenness of sense-perception. We do not call a hound sagacious in following a clear trail; but if he loses the scent, as at the edge of a stream, and circles around till he strikes it again, his conduct is said to be sagacious. In human affairs sagacious refers to a power of ready, far-reaching, and accurate inference from observed facts perhaps in themselves very slight, that seems like a special sense; or to a similar readiness to foresee the results of any action, especially upon human motives or conduct — a kind of prophetic common sense. Sagacious is a broader and nobler word than shrewd, and not capable of the invidious sense which the latter word often bears; on the other hand, sagacious is less lofty and comprehensive than wise in its full sense, and more limited to matters of direct practical moment. Compare ASTUTE; WISDOM.

    able, acute, apt, clear-sighted, discerning, intelligent, judicious, keen, keen-sighted, keen-witted, perspicacious, quick of scent, quick-scented, sagacious, sage, sensible, sharp, sharp-witted, shrewd, wise

    absurd, dull, foolish, futile, ignorant, irrational, obtuse, senseless, silly, simple, sottish, stupid, undiscerning, unintelligent

How to use rational in a sentence?

  1. Norman Douglas:

    A man can believe a considerable deal of rubbish, and yet go about his daily work in a rational and cheerful manner.

  2. Michael Kitces:

    It’s not too late for young people to dial down their exposure to a level they can tolerate, make a change when things are down 10 percent instead of 40 percent. Things can get worse, and then you’ll make really non-rational, emotional decisions.

  3. Eric Hoffer:

    The link between ideas and action is rarely direct. There is almost always an intermediate step in which the idea is overcome. De Tocqueville points out that it is at times when passions start to govern human affairs that ideas are most obviously translated into political action. The translation of ideas into action is usually in the hands of people least likely to follow rational motives. Hence, it is that action is often the nemesis of ideas, and sometimes of the men who formulate them. One of the marks of the truly vigorous society is the ability to dispense with passion as a midwife of action - the ability to pass directly from thought to action.

  4. Thierry Bros:

  5. John Banzhaf:

    In all too many cases, we have political correctness now becoming political craziness, students are making demands -- faculty, deans, presidents are yielding, resigning [to them]. At the very least, they hold meetings and conferences. We didn't do that. Student groups made more than a dozen literally crazy demands with no rational basis and our university ignored them and nothing has happened.
