Jacob Bronowski was, with Kenneth Clarke, the greatest popularizer of serious ideas in Britain between the mid 1950s and the early 1970s. Trained as a mathematician, he was equally at home with painting and physics, and wrote a series of brilliant books that tried to break down the barriers between 'the two cultures'. He denounced 'the destructive modern prejudice that art and science are different and somehow incompatible interests'. He wrote a fine book on William Blake while running the National Coal Board's research establishment. The Common Sense of Science, first published in 1951, is a vivid attempt to explain in ordinary language how science is done and how scientists think. He isolates three creative ideas that have been central to science: the idea of order, the idea of causes and the idea of chance. For Bronowski, these were common-sense ideas that became immensely powerful and productive when applied to a vision of the world that broke with the medieval notion of a world of things ordered according to their ideal natures. Instead, Galileo, Huyghens and Newton and their contemporaries imagined 'a world of events running in a steady mechanism of before and after'. We are still living with the consequences of this search for order and causality within the facts that the world presents to us.
Bernard Lonergan (1904-1984) was a noted Canadian philosopher and theologian. He devoted his life to articulating a generalized method of inquiry and its implications, not only for the human and natural sciences, but also for a better world and a higher quality of human life. His own clear vision showed him the need to overcome the terrible fragmentation of knowledge and life in our time. The struggle to achieve an integrated view is the theme that unified the body of his work. In the history of that struggle, Understanding and Being plays a central role. Published a year after his profound and complex Insight, it is the edited transcription of some thirty hours of Lonergan's lectures on that seminal book. Understanding and Being serves as a guide to the very challenging terrain of Insight, or, as one commentator put it, if Insight is the Everest in the range of Lonergan's works, Understanding and Being is the approach through rolling foothills. This edition, the second, incorporates more of the historical setting in the text and adds a wealth of explanatory notes, as well as previously unedited discussions that followed the lectures.
