| Paragraph 1 |
Quantity is either discrete or continuous. |
| Paragraph 2 |
Instances of discrete quantities are number and speech; |
| Paragraph 3 |
In the case of the parts of a number, there is no common
boundary at
which they join. |
| Paragraph 4 |
The same is true of speech. |
| Paragraph 5 |
A line, on the other hand, is a continuous quantity, for it is
possible to find a common boundary at which its parts join. |
| Paragraph 6 |
Space and time also belong to this class of quantities. |
| Paragraph 7 |
Quantities consist either of parts which bear a relative position
each to each, or of parts which do not. |
| Paragraph 8 |
Strictly speaking, only the things which I have mentioned belong
to the category of quantity: |
| Paragraph 9 |
Quantities have no contraries. |
| Paragraph 10 |
Again, whether we define them as quantitative or not, they have no
contraries: |
| Paragraph 11 |
Moreover, if these were contraries, they would themselves be
contrary to themselves. |
| Paragraph 12 |
It is in the case of space that quantity most plausibly appears to
admit of a contrary. |
| Paragraph 13 |
Quantity does not, it appears, admit of variation of degree. |
| Paragraph 14 |
The most distinctive mark of quantity is that equality and
inequality are predicated of it. |
| Paragraph 15 |
That which is not a quantity can by no means, it would seem, be
termed equal or unequal to anything else. |
