"What was good enough two hundred thousand years ago no longer works very well. Davis makes his case with illuminating examples from everyday life. Caveman Logic is written with wit, humor, and compassion. A must-read for those searching beyond superstition and fear to understand our place in the universe." - Prof. Harry M.B. Hurwitz
"Hank Davis does a terrific job helping readers understand how ways of thinking that were both reasonable and advantageous in caveman days become illogical - and potentially destructive - when they are overextended to modern times. A stimulating, thought-provoking book!" - Madeleine Van Hecke
