Definition:Figure of Categorical Syllogism/II

Definition
The second figure of a categorical syllogism is the pattern where:


 * In the major premise, the middle term is placed second
 * In the minor premise, the middle term is placed second.

Let $P$ denote the primary term, $S$ denote the secondary term and $M$ denote the middle term of a categorical syllogism.

Then the second figure can be tabulated as: where $\mathbf \Phi_1$, $\mathbf \Phi_2$ and $\mathbf \Phi_3$ each denote one of the categorical statements $\mathbf A$, $\mathbf E$, $\mathbf I$ or $\mathbf O$.
