Chapter 3. The Logic of Relatives (cont.)

§4. Classification of Relatives (cont.)

227.   These different classes have the following relations.  Every negative of a concurrent and every alio-relative is both an opponent and the negative of a self-relative.  Every concurrent and every negative of an alio-relative is both a self-relative and the negative of an opponent.

There is only one relative which is both a concurrent and the negative of an alio-relative;  this is ‘identical with ──’.

There is only one relative which is at once an alio-relative and the negative of a concurrent;  this is the negative of the last, namely, ‘other than ──’.

The following pairs of classes are mutually exclusive, and divide all relatives between them:

No relative can be at once either an alio-relative or the negative of a concurrent, and at the same time either a concurrent or the negative of an alio-relative.

228.   We may append to the symbol of any relative a semicolon to convert it into an alio-relative of a higher order.  Thus will denote a ‘lover of ── that is not ──’.
