Truth, reason, and objectivity--can we survive without them? What happens to law, science, and the pursuit of social justice when such ideas and ideals are rejected? These questions are at the heart of the controversies between traditionalists and "postmodernists" that Barbara Herrnstein Smith examines in her wide-ranging book, which also offers an original perspective on the perennial--perhaps eternal--clash of belief and skepticism, on our need for intellectual stability and our experience of its inevitable disruption.

Focusing on the mutually frustrating impasses to which these controversies often lead and on the charges--"absurdity," "irrationalism," "complicity," "blindness," "stubbornness"--that typically accompany them, Smith stresses our tendency to give self-flattering reasons for our own beliefs and to discount or demonize the motives of those who disagree with us. Her account of the resulting cognitive and rhetorical dynamics of intellectual conflict draws on recent research and theory in evolutionary biology, neuroscience, developmental psychology, and the history and sociology of science, as well as on contemporary philosophy and language theory.

Smith's analyses take her into important ongoing debates over the possibility of an objective grounding of legal and political judgments, the continuing value of Enlightenment rationalism, significant challenges to dominant ideas of scientific truth, and proper responses to denials of the factuality of the Holocaust. As she explores these and other controversies, Smith develops fresh ways to understand their motives and energies, and more positive ways to see the operations of intellectual conflict more generally.

Every day, corporations are connecting the dots about our personal behavior—silently scrutinizing clues left behind by our work habits and Internet use. The data compiled and portraits created are incredibly detailed, to the point of being invasive. But who connects the dots about what firms are doing with this information? The Black Box Society argues that we all need to be able to do so—and to set limits on how big data affects our lives.

Hidden algorithms can make (or ruin) reputations, decide the destiny of entrepreneurs, or even devastate an entire economy. Shrouded in secrecy and complexity, decisions at major Silicon Valley and Wall Street firms were long assumed to be neutral and technical. But leaks, whistleblowers, and legal disputes have shed new light on automated judgment. Self-serving and reckless behavior is surprisingly common, and easy to hide in code protected by legal and real secrecy. Even after billions of dollars of fines have been levied, underfunded regulators may have only scratched the surface of this troubling behavior.

Frank Pasquale exposes how powerful interests abuse secrecy for profit and explains ways to rein them in. Demanding transparency is only the first step. An intelligible society would assure that key decisions of its most important firms are fair, nondiscriminatory, and open to criticism. Silicon Valley and Wall Street need to accept as much accountability as they impose on others.
