All Optimists - without exception - are Social Darwinists ; all Pessimists are Altruists

Always the OPTIMIST

Its a Fact. Its a Dogma, a Law, a Commandment you can carve in stone - by definition, all 'blue sky' optimists must be Social Darwinists. Just as, again by definition, all cautious, skeptic, 'grounded' pessimists must be altruists.

Are there any limits to human efforts to control Nature ? Blue Sky scientists don't see any...

think tank "boiler room"

But today's Grounded scientist disagrees strongly. Perhaps they are simply tired of seeing this "there are no limits" line pushed endlessly by politicians, think tanks and retired scientists like some old fashioned high pressure "boiler room" scam.
