While Descartes called the union of mind and matter a conjunction through power, Geulincx named it a miracle.
Whereas Descartes made the union between them a violent collocation, Geulincx practically called it a miracle.
We see from this that Geulincx has carried to its limit the dualistic basis of Descartes.
According to Geulincx neither the soul works immediately upon the body, nor the body immediately upon the soul.
Once more God intervenes to solve the difficulty, but after a fashion much less crude than the miraculous apparatus of Geulincx.
