There is good reason to believe, following the parallelism of the two realms, that of final causes and that of efficient causes, that God has established in the universe a connexion between punishment or reward and bad or good action, in accordance wherewith the first should always be attracted by the second, and virtue and vice obtain their reward and their punishment in consequence of the natural sequence of things, which contains still another kind of pre established harmony than that which appears in the communication between the soul and the body.
