Note: The terms instinctive belief, instinctive judgment,
      instinctive cognition, are expressions not ill adapted
      to characterize a belief, judgment, or cognition,
      which, as the result of no anterior consciousness, is,
      like the products of animal instinct, the intelligent
      effect of (as far as we are concerned) an unknown
      cause. --Sir H. Hamilton.
Syn: Natural; voluntary; spontaneous; original; innate;
     inherent; automatic.
