Reading and the History of Race in the Renaissance84
Aristotle’s model of physics is structured around a central concept of hylo-
morphism (wood [matter]; shape). Developed most fully in the Physics and
Metaphysics, this concept provided a way to understand the relationship
between form and matter, and in particular, for articulating how matter
was realized in and through form. Aristotle’s version of hylomorphism was
intended as the cornerstone of his commitment to dualism. is model
of physics was a modification of Plato’s theory of “Forms.” (Plato’s forms
were transcendent; they gave shape to physical bodies, but themselves
pre-existed and transcended such bodies; Aristotle’s forms were instead
immanent and could only be separated from primary matter hypothet-
ically and speculatively, rather than actually.) On the other hand, hylo-
morphism was also Aristotle’s corrective to natural philosophies, such as
those of Empedocles and Democritus, which focused almost entirely on
matter and seemed to ignore form and essence.

In differentiating himself from both Plato and the pre-Socratics,
Aristotle is interested in trying to understand in what sense primary mat-
ter (which is distinct from substance, though never in fact achieved with-
out it, but which can only be defined as “that which becomes,” Physics
190a33–34) does and does not change in that process of becoming sub-
stance. Matter is that which survives change, and, through form, matter
both “comes to be and ceases to be in one sense, while in another it does
not” (Physics 192a25–26). From the kind of perspective that Empedocles
took, nature is all about matter: “nature is the underlying matter of
things which have in themselves a principle of motion or change” (Physics
193a28–29).

Aristotle, by contrast, insisted that form was the defining
feature of substance: “nature is the shape or form which is specified in the
definition of the thing” (193a30–31).
Aristotle differentiates matter from form but does so by way of a sec-
ondary distinction that he makes between art and nature. On the one
hand, art differs from nature because it does not have an “innate impulse
to change” (Physics 192b17–18). A wooden statue may decay, but that is a
change to the wood, as a thing of nature, rather than to the statue itself,
as a thing of art. Works of art thus do not participate in the process of
becoming, the transformation of matter into substance through form, in
quite the same way that nature does. In keeping with this, artificial things
will have causes that are external, whereas living things have causes that
are internal. On the other hand, art provides what turns out to be the
best examples of how matter becomes substance. Primary matter is hard
to grasp: it cannot be apprehended in its own right and, while it underlies
form, it is never truly distinct or separable from it. Teleology (“for the
