What is the role of ethics in American foreign policy? The Trump Administration has elevated this from a theoretical question to front-page news. Should ethics even play a role, or should we only focus on defending our material interests? In Do Morals Matter? Joseph S. Nye provides a concise yet penetrating analysis of how modern American presidents have-and have not-incorporated ethics into their foreign policy. Nye examines each presidency during theAmerican era post-1945 and scores them on the success they achieved in implementing an ethical foreign policy. Alongside this, he evaluates their leadership qualities, explaining which approaches work and which ones do not.

Moral thinking pervades our practical lives, but where did this way of thinking come from, and what purpose does it serve? Is it to be explained by environmental pressures on our ancestors a million years ago, or is it a cultural invention of more recent origin? In The Evolution of Morality, Richard Joyce takes up these controversial questions, finding that the evidence supports an innate basis to human morality. As a moral philosopher, Joyce is interested in whether any implications follow from this hypothesis. Might the fact that the human brain has been biologically prepared by natural selection to engage in moral judgment serve in some sense to vindicate this way of thinking—staving off the threat of moral skepticism, or even undergirding some version of moral realism? Or if morality has an adaptive explanation in genetic terms—if it is, as Joyce writes, "just something that helped our ancestors make more babies"—might such an explanation actually undermine morality's central role in our lives? He carefully examines both the evolutionary "vindication of morality" and the evolutionary "debunking of morality," considering the skeptical view more seriously than have others who have treated the subject. Interdisciplinary and combining the latest results from the empirical sciences with philosophical discussion, The Evolution of Morality is one of the few books in this area written from the perspective of moral philosophy. Concise and without technical jargon, the arguments are rigorous but accessible to readers from different academic backgrounds. Joyce discusses complex issues in plain language while advocating subtle and sometimes radical views. The Evolution of Morality lays the philosophical foundations for further research into the biological understanding of human morality.

Should we pay children to read books or to get good grades? Should we allow corporations to pay for the right to pollute the atmosphere? Is it ethical to pay people to test risky new drugs or to donate their organs? What about hiring mercenaries to fight our wars? Auctioning admission to elite universities? Selling citizenship to immigrants willing to pay? In What Money Can't Buy, Michael J. Sandel takes on one of the biggest ethical questions of our time: Is there something wrong with a world in which everything is for sale? If so, how can we prevent market values from reaching into spheres of life where they don't belong? What are the moral limits of markets? In recent decades, market values have crowded out nonmarket norms in almost every aspect of life—medicine, education, government, law, art, sports, even family life and personal relations. Without quite realizing it, Sandel argues, we have drifted from having a market economy to being a market society. Is this where we want to be?In his New York Times bestseller Justice, Sandel showed himself to be a master at illuminating, with clarity and verve, the hard moral questions we confront in our everyday lives. Now, in What Money Can't Buy, he provokes an essential discussion that we, in our market-driven age, need to have: What is the proper role of markets in a democratic society—and how can we protect the moral and civic goods that markets don't honor and that money can't buy?

Most works on moral psychology consider morality an unalloyed good. Drawing primarily on social-psychological theory and research, this book looks at morality as a problem. The problem is that we often fail live up to our own moral standards. Why?

Can animals act morally? Philosophical tradition answers "no," and has apparently convincing arguments on its side. Cognitive ethology supplies a growing body of empirical evidence that suggests these arguments are wrong. This groundbreaking book assimilates both philosophical and ethological frameworks into a unified whole and argues for a qualified "yes."

Sam Harris dismantles the most common justification for religious faith--that a moral system cannot be based on science.

Can we lead a fundamentally decent life without taking such drastic steps? Todd May has answers. He's not the sort of philosopher who tells us we have to be model citizens who display perfect ethics in every decision we make. He's realistic: he understands that living up to ideals is a constant struggle. May leads readers through the traditional philosophical bases of a number of arguments about what ethics asks of us, then he develops a more reasonable and achievable way of thinking about them, one that shows us how we can use philosophical insights to participate in the complicated world around us.
