Filosofia en clave de ciencia ficcion: las personas y sus condiciones de supervivencia en el tiempo

Disagreements about the criteria for personal identity are usually discussed by means of thought experiments, which describe counterfactual science fiction situations, in order to test the explanatory force of the different accounts. In this paper the basic analyzes of the survival of persons through time are presented and the higher plausibility of psychological criteria to solve the puzzle cases is stressed. I argue that because of their capability to account for fission and fusion cases psychological criteria rooted in a four-dimensionalist framework are in a more advantageous position than those grounded on a continuants ontology.
