The handicap principle, first proposed by Zahavi about 17 years ago, has in the past several years become widely accepted as a central unifying theory explaining many previously baffling aspects of animal signalling and communication. It is arguably the most important theoretical advance in animal behaviour in recent years. Basically, the theory states that to be effective, signals must be reliable, and to be reliable, they must be costly to the signaller. This fundamental insight is then developed to explain and illuminate much of animal and human behaviour - why the peacock's tail is so ornate, and why antelope will spend energy stetting or leaping into the air, when they see a predator, instead of running away, but also how humans test each others' commitment by imposing burdens during courtship. Signals are paid attention to only if the signal itself imposes a handicap on the signaller that would make cheating impossible or unprofitable, This book explores the very wide-ranging implications of the handicap principle, for predator-prey relations, sexual selection, parent-offspring relations, coalitions and alliances, and the persistence of altruism, in animals and also in human societies and intercellular signalling within multicellular organisms.

This Oxford Handbook offers a broad critical survey of the development of phenomenology, one of the main streams of philosophy since the nineteenth century. It comprises thirty-seven specially written chapters by leading figures in the field, which highlight historical influences, connections and developments, and offer a better comprehension and assessment of the continuity as well as diversity of the phenomenological tradition. The handbook is divided into three distinct parts. The first part addresses the way phenomenology has been influenced by earlier periods or figures in the history of philosophy. The second part contains chapters targeting prominent phenomenologists: How was their work affected by earlier figures, how did their own views change over time, and what kind of influence did they exert on subsequent thinkers? The contributions in the third part trace various core topics such as subjectivity, intersubjectivity, embodiment, spatiality, imagination etc. in the work of different phenomenologists, in order to explore how the notions were transformed, enriched, and expanded up through the century. This volume will be a source of insight for philosophers, students of philosophy, and for people working in other disciplines of the humanities, social sciences, and sciences, who are interested in the phenomenological tradition. It is an authoritative guide to how phenomenology started, how it developed, and where it is heading.
