 1      I, 1 |  syllogism, and the nature of a perfect and of an imperfect syllogism;
 2      I, 1 |        necessary.~I call that a perfect syllogism which needs nothing
 3      I, 4 |   extremes must be related by a perfect syllogism. I call that term
 4      I, 4 |        subject, there must be a perfect syllogism whenever universality
 5      I, 4 |     defined. So there will be a perfect syllogism. This holds good
 6      I, 4 |   syllogisms in this figure are perfect (for they are all completed
 7      I, 5 | position. A syllogism cannot be perfect anyhow in this figure, but
 8      I, 5 |       are so related, but not a perfect syllogism; for necessity
 9      I, 5 |     imperfect: for all are made perfect by certain supplementary
10      I, 6 | position. A syllogism cannot be perfect in this figure either, but
11      I, 6 |     imperfect (for all are made perfect by certain supplementary
12      I, 7 |   imperfect syllogisms are made perfect by means of the first figure.
13      I, 7 |        formed: if they are made perfect ostensively, because (as
14      I, 7 |         figure are clearly made perfect by these, though not all
15      I, 7 |   universal syllogisms are made perfect by converting the negative
16      I, 7 |      syllogisms are indeed made perfect by themselves, but it is
17      I, 7 |    universal, are directly made perfect by means of those syllogisms;
18      I, 14|       to all C, there will be a perfect syllogism to prove that
19      I, 14|    results, or if one it is not perfect. For the necessity results
20      I, 14|       universal there will be a perfect syllogism. For if A is possible
21      I, 14| affirmative or negative, only a perfect syllogism results in the
22      I, 15|      all the syllogisms will be perfect and establish possibility
23      I, 15|   possible for all C also. So a perfect syllogism results. Likewise
24      I, 15|    latter simple attribution, a perfect syllogism results proving
25      I, 15|       to no C.~It is clear that perfect syllogisms result if the
26      I, 15|     assertoric, there will be a perfect syllogism, just as when
27      I, 16|        related as before; and a perfect syllogism when the minor
28      I, 16|      belong to all C: and it is perfect, not imperfect: for it is
29      I, 16|        C. The syllogism will be perfect, but it will establish a
30      I, 22|         syllogisms must be made perfect by means of the first figure,
31      I, 22|          and that they are made perfect by means of the first figure.~
32      I, 23|       in these figures are made perfect by means of universal syllogisms
33      I, 24|        and when a valid, when a perfect syllogism can be formed;
34      I, 25|       said at the beginning, to perfect the syllogisms. It is clear
