 Names make no sense unless they stand in mutual relation. Mother is not mother unless she may call, under the law, somebody the father. Brother is brother to a sister. And unless he calls her sister and she calls him brother, the name is worthless. The general and the sergeant, the master and the apprentice, the army and the navy make room for each other, in the wonderful whole of names. All names belong to this holon, to society. No name is good without the others. The Pan of the universe drives people panicky, that is they lose speech. The holon of the city gives everybody a name in such a manner that everybody else now can be named by him, too (1970b, 83–84).
