The names of these ''four'' [[symbol]]s are shown to the right.

The ''four'' [[symbol]]s correspond to ''four'' different [[discourse|positions]] in each [[matheme|algorithm]] of the [[discourse|four discourses]].

Each [[matheme|algorithm]] of the [[discourse|four discourses]] has ''four'' different [[discourse|positions]] with which the ''four'' [[symbol]]s correspond.

The [[discourse|position]] of the ''four'' [[symbol]]s in each [[matheme|algorithm]] is what distinguishes the [[discourse|four discourses]] from one another.

Each of the [[discourse|four discourses]] is defined by the [[discourse|position]] of the ''four'' [[symbol]]s in its [[matheme|algorithm]].
