In this article, the author analyzes the adequate social reintegration of the prisoner as the purpose of the execution of the custodial sentence in the social and democratic state of law of the Argentine Republic. To this end, the jurist identifies the different models of social
readaptation (“readaptation for morality” and “readaptation for legality”), with their virtues and criticisms. Finally, he examines the conditions imposed by an archetype of social and democratic state of law, when adhering to one or the other of these models, and finally exposes his reasons in favor of a paradigm of minimal social readaptation.
