The Premise of the Dispossessed

The story is set in a universe where there are 2 sister planets, which run on completely different ideologies:

• Urras: an Earth-like planet, with many states, the most powerful one described as a capitalist one
• Anarres is an arid planet with an anarchic society: no rulers, no private property, and no government. 

The story follows  Shevek, a brilliant temporal physicist from Anarres. We follow him growing up on Anarres and on a trip to Urras, in a series of alternating chapters. Each chapter is a philosophical exploration of concepts such as freedom, love, or property.
