This article explores the proposal offered by Ian Hacking for the distinction between natural and social sciences—a proposal that he has defined from the outset as complex and different from the traditional ones. Our objective is not only to present the path followed by Hacking's distinction, but also to determine if it constitutes a novelty or not. For this purpose, we deemed it necessary to briefly introduce the core notions Hacking uses to establish his strategic approach to social sciences, under the assumption that they are less well known that the ones corresponding to his treatment of natural sciences.
