In classical philosophy, skepticism refers to the teachings and the traits of the 'Skeptikoi', a school of philosophers of whom it was said that they 'asserted nothing but only opined.' (Liddell and Scott) In this sense, philosophical skepticism, or Pyrrhonism, is the philosophical position that one should suspend judgment in investigations.[1]
In religion, skepticism refers to 'doubt concerning basic religious principles (as immortality, providence, and revelation).' (Merriam–Webster)
The word skepticism can characterize a position on a single claim, but in scholastic circles more frequently describes a lasting mind-set and an approach to accepting or rejecting new information. Individuals who proclaim to have a skeptical outlook are frequently called skeptics, often without regard to whether it is philosophical skepticism or empirical skepticism that they profess.
