It provides a clear account of Plato's puzzling theory of knowledge, and explains how this theory then directed his provocative views on politics, ethics and individual liberty.

    Born in Vienna in 1882, Melanie Klein became a pioneer in child psychoanalysis and developed several ground-breaking concepts about the nature and crucial importance of the early stages of infantile development. Although she was a devoted Freudian, many of her ideas were seen within the psychoanalytic movement as highly controversial, and this led to heated conflicts, particularly with Freud's daughter, Anna. Introducing Melanie Klein brilliantly explains Klein's ideas, and shows the importance of her startling discoveries which raised such opposition at the time and are only now being recognized for their explanatory power. Her concepts of the depressive position and the paranoid-schizoid position are now in common usage and her work has to be taken seriously by psychoanalysts the world over. She is also now important in many academic fields within the human sciences.

    This work traces his understanding of the cognitive realities involved in the use of language and the technical apparatus needed to represent it.

    To the public he is a figure of tragic dimensions - a brilliant scientist and author of the phenomenal best-seller A Brief History of Time, and yet confined to a wheelchair, unable to speak or write. Hawking has mastered the two great theories of 20th-century physics - Einstein's General Theory of Relativity and Quantum Mechanics - and has made breathtaking discoveris about where they break down or overlap, such as on the edge of a Black Hole or at the Big Bang origin of the Universe. Here is the perfect introduction to Hawking's work by the author, who was helped by several long discussions with Hawking in researching the book.

    It's about the broken, wrinkled, wiggly world - the uneven shapes of nature, unlike the idealized forms of Euclidean geometry. We see fractals everywhere; indeed we are fractal! Fractal Geometry is an extension of classical geometry. Using computers, it can make precise models of physical structures - from ferns to galaxies. Fractal geometry is a new language. Once you speak it, you can describe the shape of cloud as precisely as an architect can describe a house.

    Forming his economic theories in the wake of the Great Depression, John Maynard Keynes argued that a healthy economy depended on the total spending of consumers, business investors and, most importantly, governments too. Keynes formulated that governments should take control of the economy in the short term, rather than relying on the market, because, as he eloquently put it 'in the long run, we are all dead'. This graphic guide is the ideal introduction to one of the most influential economists of the 20th century, at a time when his theories may be crucial to our economic survival. Through a deft mixture of words and images, "Introducing Keynes" is a timely, accessible and enjoyable read.

    Sartre was the most famous and prolific writer in France, and one of line best known philosophers of his day.Philip Thody, a former Professor of French Literature explains the basic ideas that inspired Sartre's existential world view, paying particular attention to his concert of 'personal freedom'.

    Along the way we meet a fascinating cast of characters: Darwin's scientific predecessors, his contemporaries (including Alfred Russell Wallace, whose anticipation of natural selection forced Darwin to publish), his opponents, and his successors whose work in modern genetics provided necessary modifications to Darwin's own work.Splendidly illustrated, this clever, witty, highly informative book is the perfect introduction to Darwin's life and thought.

    Aristotle's authority extended beyond his own lifetime to influence fundamentally Islamic philosophy and medieval scholasticism. For fifteen centuries, he remained the paradigm of knowledge itself. But can Aristotelian realism still be used to underpin our conception of the world today?

    Traces the history of time from Augustine's suggestion that there is no time, to the flowing time of Newton, the static time of Einstein, and then back, to the idea that there is no time in quantum gravity.

    This book provides a clear and accessible introduction to the leading thinkers of the age, the men and women who believed that rational endeavour could reveal the secrets of the universe.

    This book follows the life and work of this prominent critical theorist, tracing his influence on modern aesthetics and cultural history as well as his particular focus on the tension between Marxism and Zionism, and between word and image in modern art.

    Beginning near the speed of light and proceeding to explorations of space-time and curved spaces, "Introducing Relativity" plots a visually accessible course through the thought experiments that have given shape to contemporary physics. Scientists from Newton to Hawking add their unique contributions to this story, as we encounter Einstein's astounding vision of gravity as the curvature of space-time and arrive at the breathtakingly beautiful field equations. Einstein's legacy is reviewed in the most advanced frontiers of physics today - black holes, gravitational waves, the accelerating universe and string theory. This is a superlative, fascinating graphic account of Einstein's strange world and how his legacy has been built upon since.

    Now genetics is exploding, and before long we will have the complete code, written in three thousand million letters of DNA, of what makes a human being.

    It affects us all. We depend on it in our daily lives, and yet many of the tools of mathematics, such as geometry, algebra and trigonometry, are descended from ancient or non-Western civilizations.Introducing Mathematics traces the story of mathematics from the ancient world to modern times, describing the great discoveries and providing an accessible introduction to such topics as number-systems, geometry and algebra, the calculus, the theory of the infinite, statistical reasoning and chaos theory. It shows how the history of mathematics has seen progress and paradox go hand in hand - and how this is still happening today.
