The Dispossessed

I have read sci fi books where they cross into religion, this one is all  philosophy and politics.  In our world there are capitalists and communists, in this world we have propertarians and dispossessed. There are also archists and anarchists not to mention the simultaneists and the sequentists.  It all revolves around the Theory of Simultaneity and the ability to travel more quickly. eg sequentially you must move to a place but in simultaneity you can be at a place. Simples!

The previous owner of my copy was moved to write notes in the margins in an attempt to get to grips with the ideas.
