Belief

Again, not much time to post, but I'm looking for a definition of belief that gets at it as a subjective experience.

• any cognitive content held as true (Wordnet)
• Mental acceptance of and conviction in the truth, actuality, or validity of something: His explanation of what happened defies belief. (American Heritage)
• the feeling of certainty that something exists or is true:
  • All non-violent religious and political beliefs should be respected equally.
  • [+ that] It is my (firm) belief that nuclear weapons are immoral.
  • His belief in God gave him hope during difficult times.
  • Recent revelations about corruption have shaken many people's belief in (= caused people to have doubts about) the police.
  • The brutality of the murders was beyond belief (= too difficult to be imagined).
  • He called at her house in the belief that (= confident that) she would lend him the money.
  (Cambridge Advanced Learner's Dictionary)
• a feeling that something exists or is true, especially one without proof (Compact Oxford English Dictionary)
• conviction of the truth of some statement or the reality of some being or phenomenon especially when based on examination of evidence (Merriam-Webster)
• acceptance by the mind that something is true or real, often underpinned by an emotional or spiritual sense of certainty (Encarta)
