The thesis of the book is that the bihemispheric structure of the brain creates two different “realities,” or experiences of reality, as a result of the different manner in which the left and right hemispheres pay attention to the world. And so it came about that the master was usurped, the people were duped, the domain became a tyranny and eventually it collapsed.”(1) He saw his master’s temperance and forbearance as weakness, not wisdom, and on his missions on the master’s behalf, adopted his mantle as his own – the emissary became contemptuous of his master.
