 [t]he important discovery is that [, in the new formulation,] the conclusion is presented in a kind of interrogative mood. But the interrogative mood does not merely mean that a question is raised. In fact, it means that the possible conjecture A becomes the subject of inquiry: the purpose is to determine whether that A is indeed plausible or not. Peirce termed such mood “the investigand mood”. Hence abduction can be viewed as the dynamic process toward a plausible conjecture and, ultimately, toward a limited set of the most plausible conjectures.
