Gull chicks beg for food from their parents. Peacocks spread their tails to attract potential mates. Meerkats alert family members of the approach of predators. But are these–and other animals–sometimes dishonest? That’s what William Searcy and Stephen Nowicki ask inThe Evolution of Animal Communication. They take on the fascinating yet perplexing question of the dependability of animal signaling systems. The book probes such phenomena as the begging of nesting birds, alarm calls in squirrels and primates, carotenoid coloration in fish and birds, the calls of frogs and toads, and weapon displays in crustaceans. Do these signals convey accurate information about the signaler, its future behavior, or its environment? Or do they mislead receivers in a way that benefits the signaler? For example, is the begging chick really hungry as its cries indicate or is it lobbying to get more food than its brothers and sisters? Searcy and Nowicki take on these and other questions by developing clear definitions of key issues, by reviewing the most relevant empirical data and game theory models available, and by asking how well theory matches data. They find that animal communication is largely reliable–but that this basic reliability also allows the clever deceiver to flourish. Well researched and clearly written, their book provides new insight into animal communication, behavior, and evolution.
This new edition is a complete revision of the Dartmouth Medal-winning set last revised in 1995. Covering a wealth of topics on the ethics of health professions, animal research, population control and the environment, the set helps researchers to consider the impact of new scientific knowledge and its potential to harm or benefit present and future generations. All bibliographies have been updated and new entries added–from cloning, to issues of privacy or censorship on the Web, cell-stem research, same-sex marriage, privatization of water access, animal rights and much more.
Thomas Carson offers the most comprehensive and up-to-date investigation of moral and conceptual questions about lying and deception. Part I addresses conceptual questions and offers definitions of lying, deception, and related concepts such as withholding information, “keeping someone in the dark,” and “half truths.” Part II deals with questions in ethical theory. Carson argues that standard debates about lying and deception between act-utilitarians and their critics are inconclusive because they rest on appeals to disputed moral intuitions. He defends a version of the golden rule and a theory of moral reasoning. His theory implies that there is a moral presumption against lying and deception that causes harm — a presumption at least as strong as that endorsed by act-utilitarianism. He uses this theory to justify his claims about the issues he addresses in Part III: deception and withholding information in sales, deception in advertising, bluffing in negotiations, the duties of professionals to inform clients, lying and deception by leaders as a pretext for fighting wars, and 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 defence of the view that honesty is a virtue.
