This book was primarily intended for the use of students of medicine, as an introduction to the study of insanity, to give them a general notion of the subject without going into much detail, and incidentally to be of use to them in examinations. It was not intended as an advanced book for those who make a special study of insanity.

This book marked a notable advance in psychiatry in that it emphasizes sharply the contrast between the older descriptive psychiatry of Kraeplin and the newer interpretative psychiatry of the present time which utilizes the psychoanalytical principles and general biological viewpoints developed by Freud and his pupils in Europe and by Meyer, Hoch, White and others. As an introduction to the study of clinical psychiatry the physician and the student will find the chapters dealing with the principles of psychology and psychopathalogy particularly helpful and stimulating.

This book is the only account of what honeybees actually see. Bees detect some visual features such as edges and colours, but there is no sign that they reconstruct patterns or put together features to form objects. Bees detect motion but have no perception of what it is that moves, and certainly they do not recognize "things" by their shapes. Yet they clearly see well enough to fly and find food with a minute brain. Bee vision is therefore relevant to the construction of simple artificial visual systems, for example for mobile robots. The surprising conclusion is that bee vision is adapted to the recognition of places, not things. In this volume, Adrian Horridge also sets out the curious and contentious history of how bee vision came to be understood, with an account of a century of neglect of old experimental results, errors of interpretation, sharp disagreements, and failures of the scientific method. The design of the experiments and the methods of making inferences from observations are also critically examined, with the conclusion that scientists are often hesitant, imperfect and misleading, ignore the work of others, and fail to consider alternative explanations. The erratic path to understanding makes interesting reading for anyone with an interest in the workings of science but particularly those researching insect vision and invertebrate sensory systems.

Exploring the management of ‘truth’ in the Kingdom of Saudi Arabia, this book aims to investigate the ways in which the official ‘truth’ is constructed and institutionalised in the country. The Politics of Truth Management in Saudi Arabia argues that there are two interrelated notions which articulate the ways in which ‘truth’ is conceptualised in Islam. One, at macro level, constitutes the trans-historical foundational principles of the religion, a set of engrained beliefs, which establish the ‘finality’, and ‘oneness’ of Islam in relation to other competing narratives. The other, at a micro level, takes place internally to find ‘truth’ within the ‘truth’. Unlike Islamic truth at the macro level, which is entrenched, the Islamic truth at the micro level refers to the various attempts by different agencies to claim to have found the ‘truth’ within the ‘truth’. Wahhabism, which is the product of an eighteenth century revivalist movement, is portrayed as the most ‘authentic’ reading of Islam. It is seen as the raison d'être for the prevailing political mechanism in the country and is introduced as an example of truth management at the micro level. Arguing that truth is not born in a power vacuum and often its construction and institutionalisation signify domination in one way or another, this book will be of interest to students of Religion, Politics, and Saudi Politics more specifically.
