What do we know about the world, the past, and ourselves? Very recently, just in the course of the last century and a half, there have been spectacular advances in our enquiries into these matters.

Using the most general labels for them we call them science, history and psychology respectively. What has been achieved in them, and where is our new knowledge leading us? These successes are the result of new technologies of enquiry which have vastly extended humanity's reach backwards in time and across previously inaccessible scales of distance, from the remotest galaxies down to the intricacies of the human brain, and yet further down to the internal structure of matter. Each step in these advances has in its turn raised new questions, questions that beforehand were not possible to ask; and one of the chief results has been to expose a paradox: the paradox of knowledge, which is that the more we know, the greater becomes the extent of our ignorance. We used to think that enquiry diminishes ignorance: the opposite is true.

The aim of Frontiers of Knowledge is to demonstrate and explain this point, and to make two further, related, and important points: that our increased knowledge and correlative increased ignorance teach us much that is new about the challenges facing enquiry, and that we need to place redoubled emphasis in our education and culture on reconnecting the different branches of knowledge so that we do not lose an overall sense of ourselves and our
