I'd forgotten all about that book. I've got it sitting on a dusty shelf somewhere. I don't agree with all of Sagans ideas but he's an amazing writer. Must be about time to pull it out again.
I only wish he could remake it now. So much has been discovered since.
But the thing I love the most is the manner in which it presents science. So easy to comprehend. No formulas, no microscopic details. Just a global picture. A long view.
