The research project “Cage glossary for people” examines different kinds of cages we can find not only in our modern societybut ever earlier in times. More specifically, triggered by Plato’s work “Allegory of the cave” and the meaning of the words “bind”, “bound”, “trap” and “cage” a study is conducted on “people cages” or jails. Cages in childhood, sleeping and cages, more or less severe punishment, cages and power games, modern cages and even the change of the use of a cage are under investigation. Finally, through the study that was conducted two questions arose; what and whitch is the cage of a man and why  since we are “fres: we are consideredto be “bound”.
