Carl Sagan. Not just a brilliant astronomer and scientist, but an all around accessible man. With logical, plausible, and hopeful thoughts on such daunting and potentially depressing topics as where we came from, why we are here, and what will happen to us in the future, he inspired millions to look both more closely at the world around them, and to look with a new perspective at the greater universe of which we occupy such a tiny part. Rather than subscribe to the millenia-old method of relying on a higher power who may or may not be there to help us, he offers real, challenging and wholly inspirational suggestions as to how we should conduct ourselves as a species and as a planetwide society to achieve our most awesome potential.
