The Dispossessed

Le Guin's 'The Dispossessed' represents the high orbit of what SF can do. Science Fiction is best, most lasting, most literate, when it is using its conventional form(s) to explore not space but us. When the vehicle of SF is used to ask big questions that are easier bent with binary planets, with grand theories of time and space, etc., we are able to better understand both the limits and the horizons of our species.

The great SF writers (Asimov, Vonnegut, Heinlein, Dick, Bradbury, etc) have been able to explore political, economic, social, and cultural questions/possibilities using the future, time, and the wide-openness of space. Ursula K. Le Guin belongs firmly in the pantheon of great social SF writers. She will be read far into the future -- not because her writing reflects the future, but because it captures the now so perfectly.
