What Is Abduction‪?‬

Abduction is a type of reasoning that has many antecedents. In The Sign of Three, Umberto Eco mentions the works of the semiologist Charles Peirce and the crime novels of Edgar Allan Poe and Arthur Conan Doyle (creator of Sherlock Holmes). Popper recognized that his idea of science as a field of "conjecture and refutations" had already been raised by Peirce. According to Javier Flax, scientific rationality is limited if it only uses deduction, induction and instrumental rationality (adapting means to ends). That is why ABDUCTION PROVIDES A CONJETURAL MODEL OF RECONSTRUCTION OF A PARTICULAR FACT. To address the question, we have summarized the essentials of "The abduction: conjectures on how to know the complexity of the singularity", by Javier Flax.
