  Early on in the Fons Vitae, we learn that the Divine Will is one of three central concepts that the human mind must set out to grasp (the workings of matter and form, and the reality of a divine Essence as primal cause are the other two central concepts). We also learn of Will that it is some sort of cosmic “intermediary between the extremes,” a role described as central to the basic underpinning of the universe (Fons Vitae 1.7, p. 9, lines 28–30; see too Fons Vitae 5.36, p 322, line 20–p. 323, line 1 for another statement of the three divisions of knowledge; in this latter context, Will is identified with Word). We learn that Will is the power of God infused in and penetrating through all things, that it is the power of unity in the universe, and that it is that which both brings forth and moves all of existence. It is also described as the divine force that maintains and sustains the essence of all things (see Fons Vitae 5.39, p. 327, lines 14–15: Will is the power [virtus] of God infused in and penetrating all things; 5.39, p. 327, lines 26–27: Will is the power [virtus] of unity; 1.2, p. 4, lines 14–15: Will is the divine power [virtus] bringing forth and moving all things; 1.5, p. 7, line 15: Will maintains and sustains the essence of all things).
