"The party really is over....The attitude that has been so appropriate this past 10,000 years, and has allowed the most exploitative-experimental people to rise inexorably if fitfully to the top, has simply ceased to be appropriate. Yet our economies are geared to the exploitative-experimental approach, and so are our political systems. So all of a sudden, or so it seems, our political and economic institutions and philosophies are out of synch with the biological and physical realities of the planet. It might be unrealistic to devise new systems that are radically different, with a radically different motivation; but if we do not do this, then we cannot seriously contemplate long-term survival. Surely it cannot be the case that the only “realistic” course is to head pell-mell for disaster? Is that what the level-headed, sober-suited people are arguing? Our position seems not merely precarious, but ludicrous."
