The work explores some issues related to beliefs, logic, and rational decisions, taking Newcomb's paradox as a reference. The article explores the ways in which this paradox has traditionally been seen, pointing out that it is not possible to speak of an incorrect position, given the conceptual basis that both argumentative strategies use, although one of them stands out due to the practical consequences it has.
The problem of determinism is also dealt with, and it is argued - following Dennett - that determinism is not necessarily incompatible with freedom.
