 1      I, 4 |           term cannot be attributed. Suppose the terms are animal, man,
 2      I, 11|           will not be necessary. For suppose BC is affirmative and necessary,
 3      I, 15|    necessarily from A’s possibility. Suppose, the terms being so related,
 4      I, 15|        possible attribute for all C. Suppose that it is not possible,
 5      I, 15|            possibly belongs to no C. Suppose that it cannot belong, and
 6      I, 15|              shall have a syllogism. Suppose that A belongs to no B,
 7      I, 16|            follows is not necessary. Suppose A necessarily belongs to
 8      I, 16|              not similar in quality, suppose first that the negative
 9      I, 16|          that A belongs to no C. For suppose A to belong to all C or
10      I, 17|              may belong to no A. For suppose it to follow and assume
11      I, 17|      convertible.~This being proved, suppose it possible that A may belong
12      I, 17|             But neither is possible. Suppose the conclusion is affirmative:
13      I, 17|        cannot belong to the subject. Suppose the conclusion is negative:
14      I, 18|              shall have a syllogism. Suppose A belongs to no B, but can
15      I, 19|              conclusion is possible. Suppose that A necessarily belongs
16      I, 19|              other problematic; i.e. suppose that A may belong to no
17      I, 19| complementary affirmative as before. Suppose A necessarily does not belong
18      I, 19|           will not belong to C; e.g. suppose that A is white, B swan,
19      I, 20|         premisses be problematic and suppose that both A and B may possibly
20      I, 20|             assertoric propositions. Suppose that A may possibly belong
21      I, 21|            premisses be affirmative: suppose that A belongs to all C,
22      I, 21|             reductio ad impossibile. Suppose that B belongs to all C,
23      I, 22|           than in the other figures. Suppose first that the premisses
24      I, 22|             AC is problematic. Again suppose one proposition is affirmative,
25      I, 22|    affirmative being necessary: i.e. suppose A may possibly belong to
26      I, 22|            not belong to some B. For suppose that A necessarily does
27      I, 24|             position will be begged. Suppose we have to prove that pleasure
28      I, 24|        isosceles triangle are equal. Suppose the lines A and B have been
29      I, 25|     established by means of A and B. Suppose that the proposition E is
30      I, 25|              be related in this way. Suppose then that A stands in this
31      I, 27|           which follows one must not suppose to follow as a whole, e.g.
32      I, 28|        clearer in the following way. Suppose the consequents of A are
33      I, 28|           possibly belong to A by D. Suppose again that the attributes
34      I, 29|       belongs to none of the Es. For suppose A to belong to some E: then
35      I, 29|            from the same terms, e.g. suppose it has been proved that
36      I, 34|            of the premiss well, e.g. suppose A to be health, B disease,
37      I, 36|            are negative. But we must suppose the verb "to belong" to
38      I, 41|            of all of it.~We must not suppose that something absurd results
39      I, 44|             instance if a man should suppose that unless there is one
40      I, 46|           some difference whether we suppose the expressions "not to

43     II, 5 |              that B belongs to C. Or suppose it is necessary to prove
44     II, 5 |        convertible with one another. Suppose the proposition AC has been
45     II, 5 |    particular premiss may be proved. Suppose that A has been proved of
46     II, 8 |              some" to "not to some". Suppose that A been proved of C,
47     II, 8 |           the syllogism is negative. Suppose it has been proved that
48     II, 8 |            but no refutation at all. Suppose that A has been proved of
49     II, 9 |            premisses can be refuted. Suppose that A belongs to no B,
50     II, 10|        refuted and in all the moods. Suppose it has been proved that
51     II, 10|      original syllogism is negative. Suppose it has been proved that
52     II, 11|       figures, but not in the first. Suppose that A belongs not to all
53     II, 11|         negatives can all be proved. Suppose that A belongs to no B,
54     II, 11|              B. Clearly then we must suppose the contradictory.~Again
55     II, 11|             the contradictory.~Again suppose that A belongs to some B,
56     II, 11|       problem in hand is not proved. Suppose that A belongs to all B,
57     II, 11|           contradictory that we must suppose.~To prove that A does not
58     II, 11|             belong to all B, we must suppose that it belongs to all B:
59     II, 11|             Consequently we must not suppose that A belongs to some B,
60     II, 12|         figures this also is proved. Suppose that A does not belong to
61     II, 12|              this is impossible (for suppose it to be clear that C belongs
62     II, 12|            When A belongs to some B, suppose that A belongs to no B,
63     II, 12|              the first figure.~Again suppose that A belongs to some B,
64     II, 12|             does not belong to an B, suppose it does belong to all B,
65     II, 13|           formed in the last figure. Suppose that A does not belong to
66     II, 13|              When A belongs to no B, suppose A belongs to some B, and
67     II, 14|           known, nor that one should suppose beforehand that it is true
68     II, 14|             other it is necessary to suppose beforehand that it is not
69     II, 14|              negative in the middle. Suppose that A has been proved to
70     II, 14|             the middle figure. Again suppose it has been proved that
71     II, 14|              belong to some C.~Again suppose it has been proved in the
72     II, 14|              the first figure.~Again suppose it has been proved in the
73     II, 16|            what those persons do who suppose that they are constructing
74     II, 17|              connexion upwards; e.g. suppose that A belongs to B, E to
75     II, 19|            middle terms. For example suppose that A is to be inferred
76     II, 21|             think the opposite true. Suppose that A belongs to B and
77     II, 21|             of a single series; e.g. suppose A belongs to B, B to C,
78     II, 21|            false, that any one could suppose the essence of good to be
79     II, 22|          will be convertible with A. Suppose B does not belong to A;
80     II, 25|             A belongs to C. Or again suppose that the terms intermediate
81     II, 27|    concomitant of this woman, people suppose it has been proved that
82     II, 27|          soul are affected together. Suppose this sign is the possession
