 When focusing on the nature of the individual causes seriatim, Suárez begins by dividing the four causes into the internal and external (or intrinsic and extrinsic; DM XII 3.19). Formal and material causes are internal, whereas efficient and final causes are external. A thing's matter accounts for the material features of the thing which it constitutes, without actually being that thing; and the same again for the form. So, for example, a statue is malleable because it is made of bronze, though that quantity of bronze in virtue of which it is malleable is not identical with the statue, since it may exist when the statue does not; and the bronze statue is a statue of Hermes because of its form, which, like its matter, can be readily thought of as a constituent of the statue without being identified with the statue, which is itself neither exhaustively matter nor form, but a composite of both. In Suárez's terms, then, matter and form conform to the general definition of a cause, because each in its own way infuses something beyond itself—the statue—with its existence and features. Each manages to give some manner of being (esse) to the statue, even they are in different ways internal to the entity whose being they influence. By contrast, neither of the statue's external causes—the efficient cause, that is, the sculptor who sculpts the bronze so as to give it this or that form, and its final cause, that is, the goal or reason the sculptor has in view when sculpting—is a constituent of the statue. They are thus external causes in Suárez's terminology.
