. Now if 'man' and 'not-man'
mean nothing different, obviously 'not being a man' will mean
nothing different from 'being a man'; so that 'being a man' will be
'not being a man'; for they will be one. For being one means
this-being related as 'raiment' and 'dress' are, if their definition
is one. And if 'being a man' and 'being a not-man' are to be one, they
must mean one thing. But it was shown earlier' that they mean
different things.-Therefore, if it is true to say of anything that
it is a man, it must be a two-footed animal (for this was what 'man'
meant); and if this is necessary, it is impossible that the same thing
should not at that time be a two-footed animal; for this is what
'being necessary' means-that it is impossible for the thing not to be.
It is, then, impossible that it should be at the same time true to say
the same thing is a man and is not a man.
The same account holds good with regard to 'not being a man',
for 'being a man' and 'being a not-man' mean different things, since
even 'being white' and 'being a man' are different; for the former
terms are much more different so that they must a fortiori mean
different things. And if any one says that 'white' means one and the
same thing as 'man', again we shall say the same as what was said
before, that it would follow that all things are one, and not only
opposites. But if this is impossible, then what we have maintained
will follow, if our opponent will only answer our question
