SIGNED by Sagan on the half-title “Science is only a Latin word for knowledge. Knowledge is our destiny.”

In his brief exploration on the evolution of human intelligence, Sagan traces its remarkable evolutionary path, delving into the mechanisms and environmental forces that may have influenced its growth. He presents his speculations in a compelling amalgamation of anthropology, evolutionary biology, psychology, and computer science. 

Central to Sagan’s thesis is the concept of the “extra-genetic learning system.” This theory proposes that human progress hinges crucially on our ability to transfer knowledge across generations and peers without relying solely on genetic inheritance or personal trial and error. This capability dramatically hastens our learning processes, enabling swift adaptation to changing environments and advancing survival skills beyond the slow pace of genetic evolution. Further, Sagan insightfully explores the relationship between evolution and civilization and offers masterful insights on the Cosmic Calendar to make vast, complex concepts like the age of the universe more comprehensible.
