This is an audiobook about the big questions in life: knowledge, consciousness, fate, God, truth, goodness, justice. It is for anyone who believes there are big questions out there, but does not know how to approach them. Think sets out to explain what they are and why they are important. Simon Blackburn begins by putting forward a convincing case for the study of philosophy and goes on to give the listener a sense of how the great historical figures such as Descartes, Hume, Kant, and Wittgenstein have approached its central themes. Each chapter explains a major issue, and gives the listener a self-contained guide through the problems that philosophers have studied. The large scope of topics covered range from skepticism, the self, mind and body, and freedom to ethics and the arguments surrounding the existence of God. Lively and approachable, this audiobook is ideal for all those who want to learn how the basic techniques of thinking shape our existence.
