 1      I, 3 |               3~The same manner of conversion will hold good also in respect
 2      I, 3 |           necessarily A, admits of conversion like other negative statements,
 3      I, 3 |           proved in the sequel. In conversion these premisses will behave
 4      I, 7 |         always results by means of conversion. It is evident also that
 5      I, 7 |           a conclusion by means of conversion, and conversion produces
 6      I, 7 |           means of conversion, and conversion produces the first figure:
 7      I, 8 |           be necessary by means of conversion, in the same manner as in
 8      I, 10|            is B possible of C: for conversion is possible without modifying
 9      I, 11|         must belong to some B: for conversion is possible. Similarly also
10      I, 13|       affirmative in form admit of conversion by opposition, e.g. "it
11      I, 14|         necessity results from the conversion.~But if one of the premisses
12      I, 15|          sometimes it requires the conversion of one premiss. We have
13      I, 15|         impossibile, others by the conversion of the problematic premiss,
14      I, 15|            be possible by means of conversion when the major premiss is
15      I, 16|           syllogism is possible by conversion, as above; but when it is
16      I, 17|          and to all C. By means of conversion no syllogism will result:
17      I, 18|           can be drawn by means of conversion, as before. Again if both
18      I, 19| proposition (the proof proceeds by conversion); but when the affirmative
19      I, 20|          the first figure again by conversion. But if both premisses should
20      I, 20|           first figure by means of conversion. But if one of the premisses
21      I, 20|           have the first figure by conversion. But if both premisses should
22      I, 22|          can be formed by means of conversion; but if it is necessary
23      I, 45|     statement AB does not admit of conversion, nor would there be a syllogism
24      I, 45|       premisses is universal after conversion.~Syllogisms in the third
25      I, 45|         negative does not admit of conversion.~It is clear then that the
26     II, 6 |         not be demonstrated by the conversion of AB: for it turns out
27     II, 8 |          result whichever form the conversion takes. This will be made
28     II, 8 |           to refute universally by conversion the premiss which concerns
29     II, 8 |           conclusion reached by O, conversion lacks universality, but
30     II, 9 |          to it, whichever form the conversion of the conclusion may take.
31     II, 9 |            a manner similar to the conversion: I mean, if the conclusion
32     II, 10|        premisses arrived at by the conversion must be particular, or the
33     II, 11|           11~It is clear then what conversion is, how it is effected in
34     II, 11|          figures. For it resembles conversion, differing only in this:
35     II, 11|            differing only in this: conversion takes place after a syllogism
36     II, 11|            whatever moods admit of conversion admit also of the reduction
37     II, 14|           are obtained by means of conversion, so that we obtain immediately
38     II, 16|            if one were to make the conversion, then he would be doing
39     II, 22|            to all C, and C to B by conversion, A will belong to all B.~
40     II, 23|           the terms are related in conversion, and in respect of being
