Necesidad de origen e Identidad fundada; consideraciones críticas en torno al argumento de Forbes

the work presents and criticizes the argument developed by Graeme Forbes for the necessity of origin. In first place, the argument is studied in detail, considering in particular its presuppositions and the relation it has with the argument of Saul Kripke and Nathan Salmon for the same conclusion. In second place, the difficulties of Forbes’s argument are discussed, comparing it with the criticism by Teresa Robertson. It appears that it is (i) at best, inconclusive, and (ii) in the worst case, incoherent.
