Understanding our humanity - the essence of who we are - is one of the deepest mysteries and biggest challenges in modern science. Why do we have bad moods? Why are we capable of having such strange dreams? How can metaphors in our language hold such sway on our actions? As we learn more about the mechanisms of human behavior through evolutionary biology, neuroscience, anthropology, and other related fields, we're discovering just how intriguing the human species is.

Critical theory emerged in the 1920s from the work of the Frankfurt School, the circle of German-Jewish academics who sought to diagnose—and, if at all possible, cure—the ills of society, particularly fascism and capitalism. In this book, Stephen Eric Bronner provides sketches of leading representatives of the critical tradition (such as George Lukács and Ernst Bloch, Theodor Adorno and Walter Benjamin, Herbert Marcuse and Jurgen Habermas) as well as many of its seminal texts and empirical investigations.

In this new edition, Steve Bruce discusses the continuing arguments for social egalitarianism, considering issues such as gay marriage, women in combat roles, and the 2010 Equality Act to debunk contemporary arguments against parity.

Philosophical Investigations was published in 1953, two years after the death of its author. In the preface written in Cambridge in 1945 where he was professor of philosophy he states: ‘Four years ago I had occasion to re-read my first book (the Tractatus Logico-Philosophicus) and to explain its ideas to someone. It suddenly seemed to me that I should publish those old thoughts and the new ones together: that the latter could be seen in the right light only by contrast with and against the background of my old way of thinking.’

This short, smart book tells you everything you need to know about "nothing". What remains when you take all the matter away? Can empty space - "nothing" - exist? To answer these questions, eminent scientist Frank Close takes us on a lively and accessible journey that ranges from ancient ideas and cultural superstitions to the frontiers of current research, illuminating the story of how scientists have explored the void and the rich discoveries they have made there.

Economics has the capacity to offer us deep insights into some of the most formidable problems of life and offer solutions to them, too. Combining a global approach with examples from everyday life, Partha Dasgupta describes the lives of two children who live very different lives in different parts of the world: the Midwest USA and in Ethiopia. He compares the obstacles facing them and the processes that shape their lives, their families, and their futures. He shows how economics uncovers these processes, finds explanations for them, and how it forms policies and solutions.

Martin Heidegger, considered by some to be the greatest charlatan ever to claim the title of "philosopher", by some as an apologist for Nazism, and by others as an acknowledged leader in continental philosophy, is probably the most divisive thinker of the 20th century. In the second edition of this Very Short Introduction audiobook, Michael Inwood focuses on Heidegger's most important work, Being and Time, to explore its major themes of existence in the world, inauthenticity, guilt, destiny, truth, and the nature of time.

What is socialism? Does it have a future, or has it become an outdated ideology in the 21st century? This audiobook considers the major theories in socialism and explores its historical evolution from the French Revolution to the present day. Michael Newman argues that socialism has always been a diverse doctrine, while nevertheless containing a central core of interconnected values and goals: a critique of capitalism; an optimistic view of human beings; and the belief that it is possible to establish societies based on egalitarianism, social solidarity, and cooperation.

One of the leading philosophical movements of the 20th century, existentialism has had more impact on literature and the arts than any other school of thought. Focusing on the leading figures of existentialism, including Sartre, Nietzsche, Heidegger, Kierkegaard, de Beauvoir, Merleau-Ponty, and Camus, Thomas Flynn offers a concise account of existentialism, explaining the key themes of individuality, free will, and personal responsibility, which marked the movement as a way of life, not just a way of thinking.

Psychology is part of everyone's experience: It influences the way we think about everything from education and intelligence, to relationships and emotions, advertising and criminality. People readily behave as amateur psychologists, offering explanations for what people think, feel, and do. But what exactly are psychologists trying to do? What scientific grounding do they have for their approach? This Very Short Introduction explores some of psychology's leading ideas and their practical relevance.

This book provides a historical account of feminism, exploring its earliest roots as well as key issues including voting rights, the liberation of the '60s, and its relevance today. Margaret Walters touches on the difficulties and inequities that women still face more than 40 years after the "new wave" of 1960s feminism, such as how successful women are at combining domesticity, motherhood, and work outside the house. She brings the subject completely up to date by providing an analysis of the current situation of women across the globe.

In The Righteous Mind, social psychologist Jonathan Haidt explores the origins of our divisions and points the way forward to mutual understanding. His starting point is moral intuition - the nearly instantaneous perceptions we all have about other people and the things they do. These intuitions feel like self-evident truths, making us righteously certain that those who see things differently are wrong. Haidt shows us how these intuitions differ across cultures, including the cultures of the political left and right.
