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.’

Kant is arguably the most influential modern philosopher, but also one of the most difficult. Roger Scruton tackles his exceptionally complex subject with a strong hand, exploring the background to Kant's work and showing why the Critique of Pure Reason has proved so enduring. 

Hegel is regarded as one of the most influential figures on modern political and intellectual development. After painting Hegel's life and times in broad strokes, Peter Singer goes on to tackle some of the more challenging aspects of Hegel's philosophy. Offering a broad discussion of Hegel's ideas and an account of his major works, Singer explains what have often been considered abstruse and obscure ideas in a clear and inviting manner. 

Schopenhauer is considered to be the most accessible of German philosophers. This book gives a succinct explanation of his metaphysical system, concentrating on the original aspects of his thought, which inspired many artists and thinkers including Nietzsche, Wagner, Freud, and Wittgenstein. Schopenhauer's central notion is that of the will-a blind, irrational force that he uses to interpret both the human mind and the whole of nature.

With his well known idiosyncrasies and aphoristic style, Friedrich Nietzsche is always bracing and provocative, and temptingly easy to dip into. Michael Tanner's introduction to the philosopher's life and work examines the numerous ambiguities inherent in his writings and explodes many of the misconceptions that have grown in the hundred years since Nietzsche wrote "do not, above all, confound me with what I am not!" 

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.

T. W. Adorno (1903-1969) was a German philosopher and social and cultural theorist. His work has come to be seen as increasingly relevant to understanding the pathologies of contemporary society evident in today's climate emergency, the financial crash, the reappearance of fascism in many countries, and the growing instability of the world order. This Very Short Introduction covers Adorno's work and life, explaining his key philosophical concepts and the philosophical background and historical context of Adorno's thinking.

Timothy Williamson tackles some of the key questions surrounding philosophy in new and provocative ways, showing how philosophy begins in common sense curiosity, and develops through our capacity to dispute rationally with each other. Discussing philosophy's ability to clarify our thoughts, he explains why such clarification depends on the development of philosophical theories, and how those theories can be tested by imaginative thought experiments, and compared against each other by standards similar to those used in the natural and social sciences.

An accessible, expert introduction to one of the greatest minds of 19th century. Whether you're completely new to him, or if you're already familiar with his work, Kierkegaard: A Single Life presents a fresh understanding of his life and thought. Kierkegaard was a brilliant and enigmatic loner whose ideas permeated culture, shaped modern Christianity, and influenced people as diverse as Franz Kafka and Martin Luther King Jr. Though few people today have read his work, that lack of familiarity with the real Kierkegaard is changing with this biography by scholar Stephen Backhouse.

How much faith should we place in what scientists tell us? Is it possible for scientific knowledge to be fully "objective"? What, really, can be defined as science? In the second edition of this very short introduction, Samir Okasha explores the main themes and theories of contemporary philosophy of science and investigates fascinating, challenging questions such as these.

Poststructuralism changes the way we understand the relations between human beings, their culture, and the world. Following a brief account of the historical relationship between structuralism and poststructuralism, this Very Short Introduction traces the key arguments that have led poststructuralists to challenge traditional theories of language and culture. 

A good book may have the power to change the way we see the world, but a great book actually becomes part of our daily consciousness, pervading our thinking to the point that we take it for granted, and we forget how provocative and challenging its ideas once were - and still are. The Structure of Scientific Revolutions is that kind of book.

Philosophy of Physics is concerned with the deepest theories of modern physics - notably quantum theory, our theories of space, time and symmetry, and thermal physics - and their strange, even bizarre conceptual implications. A deeper understanding of these theories helps both physics, through pointing the way to new theories and new applications, and philosophy, through seeing how our worldview has to change in the light of what we learn from physics.

In this Very Short Introduction audiobook, Gary Gutting presents a wide-ranging but nonsystematic exploration of some highlights of Foucault's life and thought. Beginning with a brief biography to set the social and political stage, he then tackles Foucault's thoughts on literature, in particular the avant-garde scene; his philosophical and historical work; his treatment of knowledge and power in modern society; and his thoughts on sexuality. 

Sigmund Freud revolutionized the way in which we think about ourselves. From its beginnings as a theory of neurosis Freud developed psychoanalysis into a general psychology, which became widely accepted as the predominant mode of discussing personality and interpersonal relationships. Anthony Storr goes one step further and investigates the status of Freud's legacy today and the disputes that surround it.
