 5 4 |           every sentence is not a proposition; only such are propositions
 6 4 |         types of sentence but the proposition, for this last concerns
 7 5 |         one by conjunction.~Every proposition must contain a verb or the
 8 5 |           time be added, is not a proposition. It may be asked how the
 9 5 |        expression only, and not a proposition, since it is not possible
10 5 |     simple propositions. A simple proposition is a statement, with meaning,
11 7 |           positive and a negative proposition of universal character with
12 7 |   contrary". By the expression "a proposition of universal character with
13 7 |           is a universal, but the proposition is not made as of universal
14 7 |   universal, but rather gives the proposition a universal character. If,
15 7 |      subject are distributed, the proposition thus constituted is contrary
16 7 |       circumstances, be true. The proposition "every man is every animal"
17 7 |          is white", or again, the proposition "no man is white" is the
18 7 |          the contradictory of the proposition "some men are white". But
19 7 |        owing to the fact that the proposition "man is not white" appears
20 7 |           to be equivalent to the proposition "no man is white". This,
21 7 |          its proper denial in the proposition "Socrates is not white".
22 8 |           horse and of a man, the proposition "garment is white" would
23 8 |           it is equivalent to the proposition "horse and man are white",
24 8 |          and do not form a single proposition, it is plain that the first
25 8 |           is plain that the first proposition either has more than one
26 9 |          be white; if the reverse proposition is true, it will of necessity
27 9 |        Again, if it is white, the proposition stating that it is white
28 9 |           if it is not white, the proposition to the opposite effect was
29 9 |        facts should prove the one proposition false, the opposite would
30 10|         Since the contrary of the proposition "every animal is just" is "
31 10|           both true.~Further, the proposition "no man is just" follows
32 10|         is just" follows from the proposition "every man is not just"
33 10|          man is not just" and the proposition "not every man is not just",
34 10|       not-just", follows from the proposition "some men are just"; for
35 10|           one, a certain positive proposition is also true. Thus, if the
36 10| universals, but rather a negative proposition. For instance, if to the
37 10|            on the other hand, the proposition "everything that is not
38 10|        just" is equivalent to the proposition "nothing that is not man
39 10|         contradictory to the same proposition, whereas it has been demonstrated’
40 10|           demonstrated’ that each proposition has one proper contradictory
41 10|          and one only. For of the proposition "man is white" the appropriate
42 10|         is not white", and of the proposition "white is man", if its meaning
43 10|          the contradictory of the proposition "white is not-man", and
44 10|          the contradictory of the proposition "man is white"; thus there
45 10|        two contradictories to one proposition.~It is evident, therefore,
46 11|     predicates cannot be a single proposition. For as I have explained
47 11|      cannot construct a composite proposition and say that he is a good
48 11|         to form a unity. Take the proposition "man is white of complexion
49 11|         always possible. Take the proposition "Homer is so-and-so", say "
50 11|      Homer only incidentally, the proposition being that Homer is a poet,
51 12|          the contradictory of the proposition "man is" is "man is not",
52 12|          positive or the negative proposition is true of any subject,
53 12|          same rule applies to the proposition "it is contingent that it
54 13|       propositions thus. From the proposition "it may be" it follows that
55 13|           not necessary.~From the proposition "it may not be" or "it is
56 13|           should not be. From the proposition "it cannot be" or "it is
57 13|       that it should be. From the proposition "it cannot not be" or "it
58 13|    inversion. The negative of the proposition "it is impossible" is consequent
59 13|            is consequent upon the proposition "it may be" and the corresponding
60 13|         impossible" is a positive proposition and "it is not impossible"
61 13|       separate sequences. For the proposition "it is not necessary that
62 13|         lies in the fact that the proposition "it is impossible" is equivalent,
63 13|          contrary subject, to the proposition "it is necessary". For when
64 13|          is absurd.)~Yet from the proposition "it may be" it follows that
65 13|         is absurd. But again, the proposition "it is necessary that it
66 13|          does not follow from the proposition "it may be", nor does the
67 13|          it may be", nor does the proposition "it is necessary that it
68 13|           should not be". For the proposition "it may be" implies a twofold
69 13|      remains, therefore, that the proposition "it is not necessary that
70 13|          not be" follows from the proposition "it may be". For this is
71 13|      necessarily be.~Moreover the proposition "it is not necessary that
72 13|       that which follows from the proposition "it cannot be"; for "it
73 13|      contradictory of this is the proposition "it is not necessary that
74 13|         be questioned whether the proposition "it may be" follows from
75 13|          may be" follows from the proposition "it is necessary that it
76 13|           contradictory, then the proposition "it may not be".~Now both
77 14|          affirmation; whether the proposition "every man is just" finds
78 14|         finds its contrary in the proposition "no man is just", or in
79 14|           man is just", or in the proposition "every man is unjust". Take
