As someone who grew up in the 70's I completely agree with Dr. Sagan. I believe I have read everyone of these stories mentioned. I found it astounding he continually mentions Heinlein as he is my favorite author to this day. He taught a young moldable mind (mine) to think outside of societal norms and to believe that things can be done. His stories no longer seem to fit what the PC world we live in. The one book I was surprised to not see mentioned was Stranger in a Strange Land. Maybe Dr Sagan never groked it. I have read it more than 10 times and still wonder if I grok.
