This book addresses questions in ethical theory and practical questions about lying, deception, and information disclosure in public affairs, business and professional ethics, and personal relationships. Part I is a conceptual map for the rest of the book. It proposes an analysis of the concepts of lying and deception and related concepts such as withholding information, “keeping someone in the dark,” and “half-truths.” Part II addresses questions in ethical theory. The book examines the implications of Kant's theory, act-utilitarianism, Ross's theory, and rule-consequentialism for moral questions about lying and deception. The book argues that Kant's absolutism about lying is untenable and that his moral theory doesn't commit him to being an absolutist. It also argues that the standard debates about lying and deception between act-utilitarians and their critics are inconclusive because they rest on appeals to disputed intuitions. The book defends a version of the golden rule and a theory of moral reasoning. The book's theory implies that there is a moral presumption against lying and deception that cause harm — a presumption that is at least as strong as that endorsed by act-utilitarianism. The book uses this theory to justify its claims about the issues it addresses in Part III: deception and withholding information in sales, deception in advertising, bluffing and deception in negotiations, the duty of professionals to inform their clients, lying and deception by leaders as a pretext for fighting wars (or avoiding wars), lying and deception about history (with special attention to the Holocaust), and cases of distorting the historical record by telling half truths. The book concludes with a qualified defense of the view that honesty is a virtue.
