certainty

certainty
   There are different sorts of certainty. Psychological certainty is the characteristic of someone that believes a proposition with maximal commitment, that is, so strongly that he or she could not believe any proposition more strongly. A proposition is logically certain relative to background information if it follows with maximal probability from the background information, that is, if nothing could follow from the background information with greater probability. A proposition is logically certain in itself if it is logically necessarily true. Some philosophers claim that the notions of psychological certainty and logical certainty should coincide, such that one may rationally be psychologically certain only of those propositions that are logically certain in themselves or logically certain relative to those propositions that are logically certain in themselves. Christian philosophers have, especially in the last twenty-five years, resisted this claim, arguing that one may rationally be psychologically certain of propositions that are not logically certain.
