"Great Thinkers in 60 Minutes Volume 5" comprises the five books "Adorno in 60 Minutes", "Habermas in 60 Minutes", "Foucault in 60 Minutes", "Rawls in 60 Minutes", and "Popper in 60 Minutes". Each short study sums up the key idea at the heart of each respective thinker and asks the question: "Of what use is this key idea to us today?" But above all the philosophers get to speak for themselves. Their most important statements are prominently presented, as direct quotations, in speech balloons with appropriate graphics, with exact indication of the source of each quote in the author's works. This light-hearted but nonetheless scholarly precise rendering of the ideas of each thinker makes it easy for the reader to acquaint him- or herself with the great questions of our lives. Because every philosopher who has achieved global fame has posed the "question of meaning": what is it that holds, at the most essential level, the world together? For Adorno it is the dialectical development of civilization from the Stone Age up to capitalism along with the alienation of Man from Nature that goes with it. Habermas, by contrast, sees in this historical process of development the chance to gradually improve society through the emancipatory power of language in communicative action. Foucault remains sceptical here and reveals to us the rigid structures in which we, as modern individuals, are trapped. Rawls develops a complex and compelling procedure for the creation of an ideally just state of affairs. Popper, finally, establishes a quite new theory of science whereby every scientific truth has only a provisional character so that it must eventually be relieved and replaced by better truths. In other words, the meaning of the world and thus of our own lives remains, among philosophers, a topic of great controversy. One thing, though, is sure: each of these five thinkers struck, from his own perspective, one brilliant spark out of that complex crystal that is the truth.
