The Elements

A large logical tree diagram at the top of the page illustrating the square of opposition and the logic of indefinite terms. The diagram is divided into two main branches: "man" on the left and "not-man" on the right. Each side further branches into four propositional forms: "is just," "is not just," "not-just is," and "not-just is not." Connecting lines and annotations between the branches indicate logical relations such as contradiction and subalternation.

It happens according to the underlying assumptions of the negation?

A second, smaller logical diagram below the first, also structured as a branching tree, further refining the divisions of categorical propositions and their negations.
