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. |
