Abstract: "This paper presents a new computational theory of explanatory coherence that applies both to the acceptance and rejection of scientific theories and to reasoning in everyday life. The theory consists of seven principles that establish relations of local coherence between a hypothesis and other propositions that explain it, are explained by it, or contradict it. An explanatory hypothesis is accepted if it is more coherent overall than its competitors. The power of the seven principles is shown by their implementation in a connectionist program called ECHO, which has been used to analyze such important scientific cases as Lavoisier's argument for oxygen against the phlogiston theory, Darwin's argument for evolution against creationism, and the recent debate about dinosaur extinction."
