that which is empty can nonetheless possess causal efficacy—is a point of
continued contention in the history of Buddhist philosophy, and one that
Desideri would also contest.
However, we would do Father Borri a disservice if we saw in his words
only vague allusions to and gross caricatures of points of Buddhist philos-
ophy. More importantly, we must also see the thought of Aristotle (as inter-
preted by St. Thomas Aquinas), the philosophical foundation of all the great
Jesuit missionaries to Asia. Thus, Borri speaks of an analysis of the rope that
reduces it to its threads, its threads are reduced to hemp, and hemp is re-
duced to the basic elements of air, earth, fire, and water. In Aristotle, and in
Aquinas, tments in turn are composed of materia prima, or prime
matter, a kind of pure materiality, devoid of substance and form. As such,
it does not have any concrete existence, but instead is pure potency, “mere
potentia” in Borri’s words. For Aristotle, prime matter is nonetheless real,
in the sense of being the potency for substances to change into determi-
nate tfferent conclusion,
that prime matter is in fact nothing, and hence declared that everything in
heaven and earth is nothing. It is likely for this reason that Borri describes him as “much ancienter than Aristotle, and nothing inferior to him in ca-
pacity, and the knowledge of natural things.”
Borri also alludes to Aristotle’s four causes: the material cause, the formal
cause, the efficient cause, and the final cause. In the simple case of a statue,
these would be: marble from which the statue is made, the creature or thing
depicted in the statue, the sculptor, and the end or purpose for which the statue is made. For Aquinas, both the efficient cause and the final cause are
God. According to Borri, the Buddha declared that all things “took their
origin as it were from a cause not efficient but material, from a principle
which in truth was nothing but an eternal, infinite, immutable, almighty, and to conclude, a God that was nothing, and the origin of this nothing.”
That is, the Buddha did not posit the existence of a creator God, or any other
efficient cause, declaring instead that everything is simply a transformation
of the material cause—the substance that undergoes change—and that that
substance was nothing.

Desideri describes the doctrine of emptiness in similar terms, but sees it
as the most pernicious of Buddhist doctrines because it makes the existence
of God impossible. The logical consequence of emptiness—that everything
is dependent and that there is nothing beyond this realm of dependently
