from The Century Dictionary.

  • To harden; confirm in resistance; make obdurate.
  • Hardened, especially against moral influences; wickedly resisting.
  • Hard-hearted; inexorable; unyielding; stubborn.
  • Inflexible; stiff; harsh.
  • Synonyms Obdurate, Callous, Hardened. These words all retain the original meaning of physical hardening, although it is obsolescent with obdurate. In the moral signification, the figure is most felt in the use of callous, which indicates sensibilities to right and wrong deadened by hard treatment, like callous flesh. Hardened is less definite, it being not always clear whether the person is viewed as made hard by circumstances or as having hardened himself against better influences and proper claims. Obdurate is the strongest, and implies most of determination and active resistance. See obstinate.
  • Unbending, unsusceptible, insensible.
