This is either an idea I got from Dr. Sagan, or it occurred to me after having viewed Cosmos a couple of times. Probably I'm paraphrasing the man himself.

Why isn't Cosmos, or something like it, part of the core curriculum in our schools? Countless generations of our ancestors looked up and wondered: what are those things in the night sky? They looked at each other and the natural world around them and wondered about that, too. Who are we? What is this place? How did we come to be here? And we are among the first people to have actual answers to some of those things. Real answers. Incomplete answers, to be sure, but answers nonetheless. Not only is it cheating children if a proper education and leaving them ill-prepared for modern life, it's also incredibly disrespectful to all of the people who came before us, who lived and died with no real answers at all.

The story of the cosmos, as far as we understand it, is amazing and everyone should know about it. The fact of evolutionary biology should be taught to every student regardless of whether they take a biology class. There should be an entire course on evolution by natural selection, required for graduation.

Also, why is it not a graduation requirement for high school students to design a scientifically sound experiment? Why are kids not taught the history of science and the scientific method as subjects in and of themselves?

Published by Random House but just lists 1980 with no further info. Thanks!
