  “Real contact occurs in some entity which truly and formally exists in things; for the contact itself is real, and properly and formally exists in reality; therefore it occurs in some real entity which formally exists in the thing; and yet it occurs in an indivisible thing; therefore such an indivisible entity exists formally in the thing itself.” [Francisco Suárez, Metaphysical Disputations 40, V, §19 (English translation  from Zimmerman 1996a: 160)]
