from which opposite consequences are deduced,
1.a. If one is one, it is nothing.
1.b. If one has being, it is all things.

To which are appended two subordinate consequences:
1.aa. If one has being, all other things are.
1.bb. If one is one, all other things are not.

The same distinction is then applied to the negative hypothesis:
2.a. If one is not one, it is all things.
2.b. If one has not being, it is nothing.

Involving two parallel consequences respecting the other or remainder:
2.aa. If one is not one, other things are all.
2.bb. If one has not being, other things are not.

'I cannot refuse,' said Parmenides, 'since, as Zeno remarks, we are alone,
though I may say with Ibycus, who in his old age fell in love, I, like the
old racehorse, tremble at the prospect of the course which I am to run, and
which I know so well. But as I must attempt this laborious game, what
shall be the subject? Suppose I take my own hypothesis of the one.' 'By
all means,' said Zeno. 'And who will answer me? Shall I propose the
youngest? he will be the most likely to say what he thinks, and his answers
will give me time to breathe.' 'I am the youngest,' said Aristoteles, 'and
at your service; proceed with your questions.'--The result may be summed up
as follows:--

1.a. One is not many, and therefore has no parts, and therefore is not a
