Abstract
In the Sophist, the Eleatic Stranger develops an account of non-being according to which
it is understood as a part of Different. Yet the precise language he uses to characterize
the form Non-Being and other negative forms has two variations. In the first, a negative
form is characterized as a part of the nature of Different contraposed to the nature
of the form negated. Thus, Non-Beautiful is described as ‘something different among
beings that is marked-off from some one kind and in turn contraposed with something
among beings’ (257e2-4), and Non-Being is identified as ‘the part of the nature of
Different contraposed with the being of each thing’ (258e2). In the second variation,
however, a negative form is characterized as the contraposing (antithesis) of the nature
of a part of Different relative to the nature of the form negated. Hence, Non-Beautiful
‘turns out to be a contraposing of being in relation to being’ (257e6-7) and Non-Being
is ‘the contraposing of the nature of a part of Different and of the nature of Being’
(258a11-b1). In this essay, I develop an account of the parts of Different that explains
the two variants in the Stranger’s characterization of negative forms, focusing on the
Stranger’s description of the Non-Beautiful as a part of Different. Since the Stranger’s
account of the parts of Different is based on an analogy with parts of knowledge, I begin
by examining what it means to be a part of knowledge, drawing on Socrates’ account of
knowledge in Republic V.
