The projects in this book began as a list Stefan Sagmeister found in his diary under the title "Things I have learned in my life so far." Given an incredible amount of freedom by some of his clients, he began transforming these aphorisms into typographic works; they have since appeared as French and Portuguese billboards, a Japanese annual report, on German television, in an Austrian magazine, as a New York direct mailer and as an American poster campaign. Taken together, the collection is part design project, part work of art, part examination of the pursuit of happiness. To this end, noted designer Steven Heller, art critic and curator Nancy Spector and psychologist and Happiness: The Science Behind Your Smile author Daniel Nettle contribute essays to the book. The new edition contains three additional signatures (48 pages) covering new works, such as the Dietch Gallery exhibition in SOHO that coincided with the book's opening and The Happy Film, a documentary that Stefan is launching next autumn.

Suzanne Romaine and Daniel Nettle argue that the loss of linguistic diversity is just as threatening as the loss of global biodiversity. Approximately half of all known languages have disappeared in the last five hundred years, and with the advent of global communication, the rate of extinction is accelerating to the level that, according to some, 90% of all languages are in danger of becoming extinct during the next century. The loss of both linguistic and biological diversity is part of a much larger and more serious problem - the near-total collapse of our worldwide ecosystem. Languages are enmeshed in social and geographical matrix just as animals and plants, and their demise is symptomatic of the illness and dealth of cultures and ways of life different from our own. Romaine and Nettle describe the background of this situation, how the current catastrophe occurred, and what can be done about it. They argue for the importance of maintaining diverse, localized responses to the environment, and show how the maintenance of different languages is necessarily linked to the diversity of human beings.

Writing for the general reader, Daniel Nettle tackles the question of why madness exists. He shows that there is, as long suspected, a link between madness and creative genius. He thus argues that the traits that lie behind madness have evolved because they have psychological benefits as well as psychological costs.

There are some 6,500 different languages in the world, belonging to around 250 distinct families, and conforming to numerous grammatical types. This text investigates and seeks to explain that diversity. Daniel Nettle examines why diversity evolved at all, given that the biological mechanisms underlying language are the same in all normal human beings. He then considers whether the distribution of diversity may be linked with the major patterns of human geography and prehistory. Human languages and language families are not distributed evenly: there are few in Eurasia compared to the thousands in Australasia, the Pacific, and the Americas. There is also a marked correlation between bio- and linguistic diversity. The author explains how and why this diversity arose. To do so he returns to the earliest origins of language, reconstructing the processes of linguistic change and diffusion that occurred when humans first filled the continents and, thousands of years later, turned to agriculture. He concludes by examining the causes of linguistic mortality, and why the number of the world's languages may halve before 2100. The text draws on work in anthropology, linguistics, geography, ar

It is one of the great mysteries of human nature. Why are some people worriers, and others wanderers? Why are some people so easy-going and laid-back, while others are always looking for a fight?
Written by Daniel Nettle--author of the popular book Happiness--this brief volume takes the reader on an exhilarating tour of what modern science can tell us about human personality. Revealing that our personalities stem from our biological makeup, Nettle looks at the latest findings from genetics and brain science, and considers the evolutionary origins and consequences of different personalities. The heart of the book sheds light on the "big five": Extraversion, Neuroticism, Conscientious, Agreeableness, and Openness. Using a stimulating blend of true-life stories and scientific research, Nettle explains why we have something deep and consistent within us that determines the choices we make and situations we bring about. He addresses such questions as why members of the same family differ so markedly in their natures? What is the best personality to have--a bold one or a shy one, an aggressive one or a meek one? And are you stuck with your personality, or can you change it? Life, Nettle concludes, is partly the business of finding a niche where your personality works for you. "It is a question of choosing the right pond," he notes, "and being mindful of the dangers."
Full of wisdom as well as scientific insight, this book illuminates the pluses and minuses of personality, offering practical advice about living with the nature you were born with.

Madness is the central mystery of the human psyche. Our minds evolved to give us a faithful understanding of reality, to allow us to integrate into our communities, and to help us to adapt our behaviour to our environment. Yet in serious mental illness, the mind does exactly the opposite of these things. The sufferer builds castles of imaginative delusion, fails to adapt, and becomes a stranger among their own people. Mental illness is no marginal phenomenon: it is found in all societies and all historical epochs, and the genes that underlie it are quite common. Furthermore, the traits that identify the madman are found in attenuated form in normal thinking and feeling. The persistence of madness, then, is a terrible puzzle from both an evolutionary and a human point of view. In A Midsummer Night's Dream, Shakespeare suggested a link between madness and artistic creativity: 'The lunatic, the lover, and the poet', he wrote, 'Are of imagination all compact'. Recent studies have shown that there is indeed a connection. Rates of mental illness are hugely elevated in the families of poets, writers, and artists, suggesting that the same genes, the same temperaments, and the same imaginative capacities are at work in insanity and in creative ability. Thus the reason madness continues to exist is that the traits behind it have psychological benefits as well as psychological costs. In Strong Imagination, Daniel Nettle explores the nature of mental illness, the biological mechanisms that underlie it, and its link to creative genius. He goes on to consider the place of both madness and creative imagination in the evolution of our species.

There are some 6,500 different languages in the world; they belong to around 250 distinct families and conform to numerous grammatical types. This book investigates why diversity arose, how it relates to the origins and evolution of language and culture, and whether the uneven distribution of human languages may be linked with patterns of human geography and history. Daniel Nettle draws on work in anthropology, linguistics, geography, archaeology, and evolutionary science to explain linguistic diversity. He writes clearly and accessibly: his book will appeal broadly across the human and natural sciences, as well as to the informed general reader.

Half of all known languages have disappeared in the last five hundred years and 90% of all languages are in danger of becoming extinct during the next century. The loss of both linguistic and biological diversity is part of a much larger and more serious problem - the near-total collapse of our worldwide ecosystem. Romaine and Nettle describe the background of this situation, how the current catastrophe occurred, and what can be done about it.

Evolutionary theory is driving forward our understanding of human behaviour like never before. Yet, many of us lack a firm grasp of the basics of the theory of evolution - a clear picture of what evolution is, and how and why it operates. But such clarity is essential if we are to fully understand and explore the fascinating behavioural questions that lie before us.
Evolution and Genetics for Psychology lays out the conceptual toolkit one needs in order to think in evolutionary terms - and to apply this thinking to any subject. With the toolkit firmly in place, it goes on to show how these key concepts are applied to issues of human behaviour, from sex to social relationships, to learning.
Evolution and Genetics for Psychology does not set out to teach evolutionary psychology or behavioural genetics, but explores the key fundamental principles on which such disciplines are based. If you need to understand what heritability really means, what the difference is between a gene and an allele, or whether evolutionary and social explanations are compatible, this book is the survival guide you need.

Bringing together the latest insights from psychiatry, psychology, and philosophy, Daniel Nettle sheds light on happiness, the most basic of human desires. Nettle examines whether people are basically happy or unhappy, whether success can make us happy, what sort of remedies to unhappiness work, why some people are happier than others, and much more.
The book is packed with fascinating observations. We discover the evolutionary reason why negative thoughts are more powerful than positive ones. We read that happiness varies from country to country, for example, the Swiss are much more happy than Bulgarians. And we learn that, in a poll among people aged 42 years old--peak mid-life crisis time--more than half rated their happiness an 8, 9, or 10 out of 10, and 90% rated it above 5. Nettle, a psychologist, is particularly insightful in discussing the brain systems underlying emotions and moods, ranging from serotonin, to mood enhancing drugs such as D-fenfluramine, which reduces negative thinking in less than an hour; to the part of the brain that, when electrically stimulated, provides feelings of benevolent calm and even euphoria. In the end, Nettle suggests that we would all probably be happier by trading income or material goods for time with people or hobbies, though most people do not do so.
Happiness offers a remarkable portrait of the feeling that poets, politicians, and philosophers all agree truly makes the world go round.
