As explained in the Preface, the concept of order is a tool used in mathematics
both in its more general form and under certain supplementary conditions.
This chapter first deals with partially ordered sets at the general level, then with
totally ordered sets and well-ordered sets, thus beginning the specialization line
which leads to ordinals (to be studied in the next chapter)....
