If Future is knowable, simple, controllable - then we don't need immigrants and troublemakers

But if it is not -- if we face a potential global disaster in the near future with no sure way yet to resolve it -- then maybe we need the biggest possible of all 'Big Tents' : we need everyone's ideas and everyone's critique.

Particularly those of immigrants - for their often strikingly different take on a crisis (instead of our conventional same old same old) might be just what Dr Mother Nature ordered.

For do we really still believe that the Anglo Saxon scientific establishment (all on its own) could have won the last war, without the help of the foreign born, their children and native-born troublemakers ?

Is to dream !
