Inference to the Best Explanation: Type of reasoning in which the truth of a theory or proposition is affirmed on the grounds that it best accounts for all of the available evidence. This type of inference is sometimes called "abduction" by those who think it is a type of reasoning distinct from induction or deduction.
Inference to the best explanation is common in daily life, the detective story and science. Advocates of cumulative case apologetics appeal to this kind of argument pattern in arguing for the existence of God.1
