We see the face of the Virgin Mary staring up at us from a grilled cheese sandwich and sell the uneaten portion of our meal for $37,000 on eBay. While science offers a wealth of rational explanations for natural phenomena, we often prefer to embrace the fantasies that reassured our distant ancestors. And we'll even go to war to protect our delusions against those who do not share them.
These are examples of what evolutionary psychologist Hank Davis calls "Caveman Logic." Although some examples are funny, the condition itself is no laughing matter. In this engagingly written book, Davis encourages us to transcend the mental default settings and tribal loyalties that worked well for our ancestors back in the Pleistocene age. Davis laments a modern world in which more people believe in ESP, ghosts, and angels than in evolution. Superstition and religion get particularly critical treatment, although Davis argues that religion, itself, is not the problem but "an inevitable by-product of how our minds misperform."
Davis argues, "It's time to move beyond the one-size-fits-all, safety and comfort-oriented settings that got our ancestors through the terrifying Pleistocene night." In contrast, Davis advocates a world in which "spirituality" is viewed as a dangerous rather than an admirable quality, and suggests ways in which we can overcome our innate predisposition toward irrationality. He concludes by pointing out that "biology is not destiny." Just as some of us succeed in watching our diets, resisting violent impulses, and engaging in unselfish behavior, we can learn to use critical thinking and the insights of science to guide individual effort and social action in the service of our whole species.

The first important distinction between operant and Pavlovian conditioning was made in 1928 by Polish scientists Konorski and Miller. Unaware of their work, Skinner proposed a similar analysis in 1935 of the manner in which operant and Pavlovian conditioning might differ and interact. Konorski and Miller responded to Skinner’s statement, and by 1937 the now-classic debate over "two types of conditioned reflexes" was in high gear. In the years before publication, the attention of many learning theorists had returned to the fundamental question of whether there are identifiably different forms of learning. The present volume, originally published in 1977, contains chapters that reassess our basic learning paradigms of the time. They deal with the definitional problems of isolating operant and Pavlovian conditioning, as well as the attempt to analyze the inevitable interactions that follow. These issues are examined in a variety of settings: some authors deal with operant-Pavlovian interactions directly by devising procedures to generate them; others examine operant-Pavlovian interactions by examining their possible contribution to established conditioning paradigms.

In 1993 successful psychologist and journalist Hank Davis undertook an epic journey exploring the atmosphere and culture of both minor league baseball and the small towns that embrace it. Davis shows us the warmth, quirkiness, and desperate energy of minor league ball, from encounters with future stars to those who would never make it to the "show"; from the kids selling Cracker Jacks outside the park to the aging coaches who persevere out of sheer love for the game. As Davis says, "the minor leagues are full of stories," and he tells some of the best of them here. A new afterword by the author dis-cusses where the minor league players are now. Hank Davis is a professor of psychology at the University of Guelph in Ontario, Canada.
