ABSTRACT
A Dutch literature classic tells about a boy named Johannes who finds himself in a class of crickets having a zoological lesson (Van Eeden, 1905). In this lesson the cricket teacher tells his students that all living creatures can be classified into three groups: those who jump, those who fly and those who crawl. The ability of crickets to jump places them in the highest order of beings. Humans are in the lowest order because they can neither jump nor fly.
