The book starts with a look at emotions and how they are important in our behaviour. It then considers social behaviour, looking at the adaptive differences between men and women. The next chapter considers emotion and rationality, and the mechanisms of decision making. In the following chapter, the author looks at philosophical issues, considering the relationship between the mind and brain, and considering whether the hardware/software distinction in a computer might tell us something about mind-brain interactions. The following chapter considers neuroaesthetics - the biological foundations of our appreciation of art - including visual art, literature, and music. Is art a useless ornament? Is music, to quote Steven Pinker, really just 'auditory cheescake'?
After this, the author looks at the field of neuroeconomics - how neuroscience is informing us about how we make economic choices. The wide-ranging chapters that follow consider neuroethics - the biological foundations of ethical behaviour, neuropsychiatry - the connection between neural functioning and psychiatric disorders, neuroreligion - the possible biological foundations of religious belief, and neuropolitics - how our knowlege of the emotion and rational reasoning systems might help us develop strategies to solve political problems.
