Synopsis

The brain is the focus of this fascinating portion of our journey as Dr. Sagan examines another of the intelligent creatures with whom we share the planet Earth — whales.

Then we wind through the maze of the human brain to witness the architecture of thought. We see how genes, brains and books store the information necessary for human survival.
