Abstract
The purpose of this article is to show the reasons, presentin Hobbes’ philosophy, that force us to conclude that God, as sufficientreason that necessitate the entire causal chain, is incompatible with themechanistic system presented by Hobbes in works such as Concerningbody [1655-6] and Leviathan [1651]. For this, I present the foundations ofHobbes’ doctrine of causality, as well as its connection with the mechanicalcausal influx of nature, with the aim of showing that: since all thatexists is body, or God must be corporeal and, thus, not be God — i.e.,does not satisfy the demand of self-sufficient sufficient reason —, or Godis not corporeal and, therefore, does not exist.
