Should the management of science utilize a deterministic methodology in order to be accepted as scientific? Can we in opposition apply freedom, and therefore the responsibility of those players involved, without applying a scientific approach? Examining discussions and examples obtained from the works of historians, this text offers a reflection on the methodological ways with which the researcher can write an “open” story, which recognizes that other paths that had not been taken were also possible. It also reports on how the players involved have encountered different paths that they have judged either correctly or incorrectly, possible, impossible, or certain.
