I completely agree! This series has been highly transformative in my life. I greatly respect and admire his view of the Cosmos and where we fit into it. While his ideas were often quite cosmic (get it?), he still always had such a common sense way of viewing things. I am proud to say, Carl Sagan is one of my heroes.
I have heard great things about the book
Cosmos. I plan on reading it this winter when school is out. Also, his book
Contact is very good, I'm told, and is another I plan to read.
