The Concept of Time presents Heidegger's so-called Dilthey review, widely considered the first draft of his celebrated masterpiece, Being and Time. Here Heidegger reveals his deep commitment to Wilhelm Dilthey and Count Yorck von Wartenburg. He agrees with them that historicity must be at the centre of the new philosophy to come. However, he also argues for an ontological approach to history. From this ontological turn he develops the so-called categories of Dasein. This work demonstrates Heidegger's indebtedness to Yorck and Dilthey and gives further evidence to the view that thought about history is the germ cell of Being and Time. However, it also shows that Heidegger's commitment to Dilthey was not without reservations and that his analysis of Dasein actually employs Husserl's phenomenology. The work reopens the question of history in a broader sense, as Heidegger struggles to thematize history without aligning it with world-historical events. The text also provides a concise and readable summary of the main themes of Being and Time and as such is an ideal companion to that text.

One of TIME’s Ten Best Nonfiction Books of the Decade "Meet the new Stephen Hawking . . . The Order of Time is a dazzling book." --The Sunday Times From the bestselling author of Seven Brief Lessons on Physics, Reality Is Not What It Seems, Helgoland, and Anaximander comes a concise, elegant exploration of time. Why do we remember the past and not the future? What does it mean for time to "flow"? Do we exist in time or does time exist in us? In lyric, accessible prose, Carlo Rovelli invites us to consider questions about the nature of time that continue to puzzle physicists and philosophers alike. For most readers this is unfamiliar terrain. We all experience time, but the more scientists learn about it, the more mysterious it remains. We think of it as uniform and universal, moving steadily from past to future, measured by clocks. Rovelli tears down these assumptions one by one, revealing a strange universe where at the most fundamental level time disappears. He explains how the theory of quantum gravity attempts to understand and give meaning to the resulting extreme landscape of this timeless world. Weaving together ideas from philosophy, science and literature, he suggests that our perception of the flow of time depends on our perspective, better understood starting from the structure of our brain and emotions than from the physical universe. Already a bestseller in Italy, and written with the poetic vitality that made Seven Brief Lessons on Physics so appealing, The Order of Time offers a profoundly intelligent, culturally rich, novel appreciation of the mysteries of time.

A brilliant graphic exploration of the physics and philosophy of time.

What is the relation between time and change? Does time depend on the mind? Is the present always the same or is it always different? Aristotle tackles these questions in the Physics, and Time for Aristotle is the first book in English devoted to this discussion. Aristotle claims that time is not a kind of change, but that it is something dependent on change; he defines it as a kind of 'number of change'. Ursula Coope argues that what this means is that time is a kind of order (not, as is commonly supposed, a kind of measure). It is universal order within which all changes are related to each other. This interpretation enables Coope to explain two puzzling claims that Aristotle makes: that the now is like a moving thing, and that time depends for its existence on the mind. Brilliantly lucid in its explanation of this challenging section of the Physics, Time for Aristotle shows his discussion to be of enduring philosophical interest.

This book links the philosophical perception of time and Einstein’s theory of special relativity to economic processes, showing that the phenomena of time dilation and length contraction seen in physics can be identified within – and adapted to – an economic framework. The author expands on Marx’s model of reproduction with the additional variable of time, which is represented as a relative or functional category. In addition to allowing a more precise understanding of both static and dynamic relations between economic systems, this concept examines approaches to time proposed by Smith, Marshall and Keynes, and challenges the equilibrium and disequilibrium economic models. Rohatinski suggests that by understanding the differences in economic activity perceived across different time periods we are better able to influence that activity at micro- and macroeconomic levels.

Heidegger's lecture course at the University of Marburg in the summer of 1925, an early version of Being and Time (1927), offers a unique glimpse into the motivations that prompted the writing of this great philosopher's master work and the presuppositions that gave shape to it. The book embarks upon a provisional description of what Heidegger calls "Dasein," the field in which both being and time become manifest. Heidegger analyzes Dasein in its everydayness in a deepening sequence of terms: being-in-the-world, worldhood, and care as the being of Dasein. The course ends by sketching the themes of death and conscience and their relevance to an ontology that makes the phenomenon of time central. Theodore Kisiel's outstanding translation premits English-speaking readers to appreciate the central importance of this text in the development of Heidegger's thought.

How do people perceive time? This book presents a wealth of contemporary and classical research, including some of the history and philosophy of time perception. Influential internal clock-based models of time perception receive an in-depth but non-technical introduction and discussion. The role of cognition and emotion in perceiving time is also explored, as well as questions derived from time experience in daily life, such as why time seems to pass more quickly in one situation rather than another. Classical and modern research on timing in children is reviewed, as well as work on time perception and time experience in older people. Leading recent models of animal timing are also discussed in a non-mathematical way.
