New indirect syllogistic moods

Summary/Abstract: In this paper are presented the indirect syllogisms that are divided in two categories. These syllogisms are resulting from operation applied either to the premisses, being named primary indirect syllogisms, or to the conclusion of other syllogisms, being named secondary indirect syllogisms. For the first category three new primary indirect syllogisms have been established by us, by one in the second, third and fourth figures. For the second category thirteen indirect syllogisms are proposed. So, in the total, twenty-four indirect syllogisms are resulted, by six in every figure.
