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.
