BBC - Human Universe
"Science is unreasonably effective. It's generated knowledge beyond all expectation. It's also delivered perspective. Yes, we are an insignificant speck, in an infinite universe, but we're also rare. And because we're rare, we're valuable.
So what are we to do to secure our future? Well, we must learn to value to the acquisition of knowledge for its own sake. And not just because it grows our economy or allows to us to build better bombs.
We must also learn to value the human race, and take responsibility for our own survival. Why? Because there's nobody else out there to value us or to look after us.
And finally - most important of all, we must educate the next generation in the great discoveries of science. And we must teach them to use the light of reason to banish the darkness of superstition. If we do that, then at least there's a chance this universe will remain a human one."
