5.2 The unity of the eternal change
5.2.1 Two ways in which change may be eternal
As we have seen, the starting point of the argument is the assumption that
change is eternal. Aristotle then presents the only two ways in which this in
principle may be possible:
εἴη δ᾽ ἂν συνεχῶς [1] ἢ συνεχὴς οὖσα [2] ἢ ἐφεξῆς6
As I will show in this section, these two ways in which change may exist
continuously, i.e. be eternal, are that either (1) there is one single change
which is “continuous” (συνεχής) as a whole, or (2) that change is eternal in
virtue of there being a succession of changes that follow “one after another”
(ἐφεξῆς) in some way and thereby so to speak would form an eternal
change. The sentence quoted above could accordingly be translated like
this: “it would exist continuously either [by being] continuous, or [by there
being] one [change] after another.” That these are the two basic options for
an explanation of how change may be eternal is clear from what the term
‘eternal’ represents: something x is eternal when there is no time at which x
is not. As we have just seen, this accordingly means for change that, given
that it is eternal as is stated in Phys. VIII 1, this is the case either because
there are a number of different changes that somehow are responsible for
there being eternal change, or because there is one single change; either of
the two options being the case implies that there is no time at which there
is no change.7 This, however, makes clear that the term ‘change’ in this con-
text is used in two different senses, namely as a count noun, in order to refer
to one or more individual occurrences of change, but also as a mass term in
the sense that Aristotle points out that in general some change is always
occurring, without making clear how many different individual changes this
involves, i.e. which of these two options is correct.8 Aristotle basically
argues that change, in the sense of a mass term, exists continuously, in that
6 Phys. VIII 7, 260b20–21.
7 This, of course, does not exclude the possibility that there is one single eternal change—
or several eternal changes—and at the same time a number of changes, which taken by itself
would already make change eternal. As I said, Aristotle here first of all points out the two
basic ways in which it is possible in principle to account for the eternal existence of change.
8 As we will see there is yet another ambiguity with respect to Aristotle’s usage of the term
change, namely insofar as ‘change’ as a count noun is applied in two significantly different
ways that one needs to be aware of if one is to make sense not only of the argument presented
here in Phys. VIII 7, but also of other arguments in Phys. VIII in general.
