"only one tenth of the mass of the iceberg is
Visible above the surface of the water...
The vast majority being hidden underneath."
This phenomenon is not restricted to icebergs.
"the iceberg model" is a look inside the head of a
Man who, on the surface is confined in a restrictive
Environment, and yet possesses immense potential
Within his mind. it shows how eventually the external
Pressures become so great that they throw his internal
Thought world into chaos.
