Ursula K. Le Guin, A Non-Euclidean View of California as a Cold Place to Be:
Utopia has been euclidean, it has been European, and it has been masculine. I am trying to suggest, in an evasive, distrustful, untrustworthy fashion, and as obscurely as I can, that our final loss of faith in that radiant sandcastle may enable our eyes to adjust to a dimmer light and in it perceive another kind of utopia. As this utopia would not be euclidean, European, or masculinist, my terms and images in speaking of it must be tentative and seem peculiar.
Non-European, non-euclidean, non-masculinist: they are all negative definitions, which is all right, but tiresome; and the last is unsatisfactory, as it might be taken to mean that the utopia I’m trying to approach could only be imagined by women — which is possible — or only inhabited by women — which is intolerable. Perhaps the word I need is yin. Utopia has been yang. In one way or another, from Plato on, utopia has been the big yang motorcycle trip. Bright, dry, clear, strong, firm, active, aggressive, lineal, progressive, creative, expanding, advancing, and hot. Our civilization is now so intensely yang that any imagination of bettering its injustices or eluding its self-destructiveness must involve a reversal. …To attain the constant, we must return, go round, go inward, go yinward. What would a yin utopia be? It would be dark, wet, obscure, weak, yielding, passive, participatory, circular, cyclical, peaceful, nurturant, retreating, contracting, and cold.
I have not been convincingly shown, and seem to be totally incapable of imagining for myself, how any further technological advance of any kind will bring us any closer to being a society predominantly concerned with preserving its existence; a society with a modest standard of living, conservative of natural resources, with a low constant fertility rate and a political life based upon consent; a society that has made a successful adaptation to its environment and has learned to live without destroying itself or the people next door. But that is the society I want to be able to imagine — I must be able to imagine, for one does not get on without hope.
