 1      I, 26|         particular statements can be refuted in one way only-by proving
 2      I, 36|               in which the thesis is refuted because the genus is asserted
 3     II, 8 | contradictory, both premisses may be refuted, but when it is converted
 4     II, 8 |              Thus both premisses are refuted. But neither can be refuted
 5     II, 8 |          refuted. But neither can be refuted if the conclusion is converted
 6     II, 8 |          original premiss is not yet refuted: for it is possible that
 7     II, 8 |            all C, both premisses are refuted: but if the assumption is
 8     II, 8 |           some C, neither premiss is refuted. The proof is the same as
 9     II, 9 |             The other premiss can be refuted in a manner similar to the
10     II, 9 |               the premiss AB will be refuted as before, the premiss,
11     II, 9 |      contrary neither premiss can be refuted, as also happened in the
12     II, 9 | contradictory, both premisses can be refuted. Suppose that A belongs
13     II, 9 |      original statement has not been refuted: for it is possible that
14     II, 9 |            the proposition AB is not refuted. But if the conclusion is
15     II, 9 | contradictory, both premisses can be refuted. For if B belongs to all
16     II, 10|              of the premisses can be refuted in any of the syllogisms,
17     II, 10| contradictory, both premisses may be refuted and in all the moods. Suppose
18     II, 10|            both the premisses can be refuted. For if A belongs to no
19     II, 10|      Therefore the premisses are not refuted. But when the contradictory
20     II, 10|      conclusion is assumed, they are refuted. For if A belongs to all
21     II, 10|            one way the premisses are refuted, in the other way they are
22     II, 10|           the minor extreme is alway refuted through the middle figure,
23     II, 10|              minor extreme is always refuted through the first figure,
24     II, 10|         concerns the major is always refuted through the first figure,
25     II, 11|            but the hypothesis is not refuted. Therefore it is the contradictory
