W. B. Yeats is one of the most important writers in English of the twentieth century, and the system of A Vision is generally recognized as fundamental to the power and achievement of his later poetry. Yet this strange mixture of esoteric geometry, lunar symbolism, and sweeping generalization has proven frustrating to generations of readers, who have found it obscure in both matter and presentation. This book helps readers to approach and understand the origins, structure, and implications of the system. Concentrating on the 1937 revised edition of A Vision, the treatment is divided into major topic areas with several levels: a general introduction to each topic; a fuller and deeper examination of that topic, drawing on A Vision's two versions and the manuscript background, and forming the bulk of each chapter; an examination of how the topic manifests in Yeats's literary work; full notes to explore conceptual and textual problems. The first three chapters examine the background and origins of A Vision; the central seven chapters look at the major elements involved in the system; the following four at the major processes of life and history. The main treatment ends with a summary and conclusion, and is supplemented by a glossary of terms and appendices.

Yeats, Philosophy, and the Occult is a collection of essays examining the thought of the Irish poet W. B. Yeats and particularly his philosophical reading and explorations of older systems of thought, where philosophy, mysticism, and the supernatural blend. It opens with a broad survey of the current state of Yeats scholarship, which also includes an examination of Yeats's poetic practice through a manuscript of the original core of a poem that became a work of philosophical thought and occult lore, "The Phases of the Moon." The following essay examines an area where spiritualism, eugenic theory, and criminology cross paths in the writings of Cesare Lombroso, and Yeats's response to his work. The third paper considers Yeats's debts to the East, especially Buddhist and Hindu thought, while the fourth looks at his ideas about the dream-state, the nature of reality, and contact with the dead. The fifth essay explores Yeats's understanding of the concept of the Great Year from classical astronomy and philosophy, and its role in the system of his work A Vision, and the sixth paper studies that work's theory of "contemporaneous periods" affecting each other across history in the light of Oswald Spengler's The Decline of the West. The seventh essay evaluates Yeats's reading of Berkeley and his critics' appreciation (or lack of it) of how he responds to Berkeley's idealism. The book as a whole explores how Yeats's mind and thought relate to his poetry, drama, and prose, and how his reading informs all of them.

While most of us live our lives according to the working week, we did not evolve to be bound by industrial schedules, nor did the food we eat. Despite this, we eat the products of industrialization and often suffer as a consequence. This book considers aspects of changing human nutrition from evolutionary and social perspectives. It considers what a 'natural' human diet might be, how it has been shaped across evolutionary time and how we have adapted to changing food availability. The transition from hunter-gatherer and the rise of agriculture through to the industrialisation and globalisation of diet are explored. Far from being adapted to a 'Stone Age' diet, humans can consume a vast range of foodstuffs. However, being able to eat anything does not mean that we should eat everything, and therefore engagement with the evolutionary underpinnings of diet and factors influencing it are key to better public health practice.
