By similar treatment of other conceivable alternatives he proceeds to show
that as the existent had no beginning so it can have no ending in time. From
this, by a curious transition which
Aristotle quotes as an
example of loose reasoning, he concludes that the existent can have no limit
in space either. As being thus unlimited it must be one, therefore immovable
(there being nothing else into which it can move or change), and therefore
always self-identical in extent and character. It cannot, therefore, have
any body, for body has parts and is not therefore one.
Being incapable of change one might perhaps conclude that the absolutely
existing being is incapable of any mental activity or consciousness. We have
no authority for assuming that Melissus came to this conclusion; but there
is a curious remark of Aristotle’s respecting this and previous philosophers
of the school which certain critics have made to bear some such
interpretation. He says: “Parmenides
seems to hold by a Unity in thought, Melissus by a Material unity. Hence the
first defined the One as limited, the second declared it to be unlimited.
Xenophanes made no clear
statement on this question; he simply, gazing up to the arch of heaven,
declared, The One is God.”
