 As noted, deduction and induction have been recognized as important classes of arguments for millennia; the concept of abduction is by comparison a latecomer. It is important to notice though that explanatory arguments as such are not latecomers; indeed, Aristotle’s very conception of scientific demonstration is based on the concept of explaining causes (see entry on  Aristotle).  What is recent is the conceptualization of abduction as a special class of arguments, and the term itself. The term was introduced by Peirce as a third class of inferences distinct from deduction and induction: for Peirce, abduction is understood as the process of forming explanatory hypotheses, thus leading to new ideas and concepts (whereas for him deduction and induction could not lead to new ideas or theories; see the entry on  Peirce). Thus seen, abduction pertains to contexts of discovery, in which case it is not clear that it corresponds to instances of arguments, properly speaking. In its modern meaning, however, abduction pertains to contexts of justification, and thus to speak of abductive arguments becomes appropriate. An abductive argument is now typically understood as an inference to the best explanation (Lipton 1971 [2003]), although some authors contend that there are good reasons to distinguish the two concepts (Campos 2011).
