What's that squirrel thinking as it runs across the street? Behavioral neuroscientist Marc D. Hauser asks big questions about little brains in Wild Minds: What Animals Really Think. While his subjects aren't accessible for interviews, he believes that we can gain insight into their interior lives by examining their behavior in the context of their social and physical environments. Thus, while comparing the actions of chimps, rats, honeybees, and human infants, he is careful to keep in mind that each of them has different needs that require different kinds of intelligence and emotion and ought not be judged by the same criteria. Looking at counting, mapmaking, self-understanding, deception, and other intelligent activities, Hauser shows that the birds and the bees have more on their minds than we've come to believe. Acknowledging the vast gulf of language that separates our species from all others, he still maintains that this tool is but one of many and is no better an indication of "superior" intelligence than is the bat's fantastically well-developed echolocation system. In the last chapter, Hauser looks at moral behavior and decides that animals can be "moral patients but not moral agents"--that is, their inability to attribute mental states to others keeps them blameless for their actions but their sensitivity to suffering earns them fair treatment from the rest of us. Whether or not you agree with that, you're sure to find Wild Minds a refreshing look at the thoughts of our mute cousins. --Rob Lightner
