But space travel can't ease the pressure on a planet grown too crowded not even with today's ships and probably not with any future ships-because stupid people won't leave the slopes of their home volcano even when it starts to smoke and rumble. What space travel does do is drain off the best brains: those smart enough to see a catastrophe before it happens, and with the guts to pay the price-abandon home, wealth, friends, relatives, everything-and go. That's a tiny fraction of one percent. But that's enough.
Robert A. HeinleinPeople simplify 'Apollonian' into 'mild', and 'calm', and 'cool'. But 'Apollonian' and 'Dionysian' are two sides of one coin--a nun kneeling in her cell, holding perfectly still, can be in ecstacy more frenzied than any priestess of Pan Priapus celebrating the vernal equinox.
