| Paragraph 1 |
We think we have scientific knowledge when we know the cause, and
there are four causes: |
| Paragraph 2 |
The same thing may exist for an end and be necessitated as
well. |
| Paragraph 3 |
Necessity too is of two kinds. |
| Paragraph 4 |
Of the products of man's intelligence some are never due to chance
or necessity but always to an end, as for example a house or
a statue; |
| Paragraph 5 |
It is mostly in cases where the issue is indeterminate (though
only where the production does not originate in chance, and
the end is
consequently good), that a result is due to an end, and this is true
alike in nature or in art. |
