  • Synonyms and
  • Guide, Direct, Sway; manage, control, pilot, steer. Guide implies that the person guiding accompanies or precedes, while direct need not mean more than that he gives instructions, which may be from a distance. The figurative uses of these words are not far from the same meanings. Direct may imply that we must reflect and exercise judgment, guide that we trustingly follow where we are led; but direct also means to exercise absolute authority: as, he directed all the movements of the army by telegraph from the seat of government. Sway in this connection is used of some influence, often bad and always strong, which turns us aside from what otherwise might have been our course, and in this sense is nearly equal to bias. (See comparison under authority.) We are guided or directed by principle or reason, or by a real friend, and swayed by our passions or feelings, or by unwise or unworthy associates.
