"It is unfortunate that the people who know best how to run the country are too busy cutting hair and driving cabs." - George Burns
"I am somehow less interested in the weight and convolutions of Einstein's brain than in the near certainty that people of equal talent have lived and died in cotton fields and sweatshops." -Stephen Jay Gould
To say that most humans don't have problems with slavery or aren't interested in human rights is ludicrous. The slavery abolitionist movement--people just kind of did that for fun? Same with the civil rights movement or the womens suffrage movement--those were just lackadaisical occurrences?
1: let's go help these people overcome there fucked up leaders and achive peace cuz things there are fucked
or 2: ohh new sorce of slaves
I really like Carl Sagan, but I think even here he understates the problems of the size of the cosmos and another question (which no-one ever thinks about) which is the amount of time a civilization would have to stick around for us to meet them. Human civilization has only existed for about 10,000 years, that's 1/500,000-th the age of the earth. Even if aliens existed, do they exist *now*?
well I think that the lifespam of a civilization depends on several issues.The industrial revolution which we are in recently. So far as a civilization manages to expand to other planets it gains great survavibility. Because from that point on there is a little possibility for a disaster to happen on all of the colonized worlds at the same time.
