In Our Time: Science Folgen

Melvyn Bragg and guests discuss the problems of consciousness, one of the greatest mysteries facing science and philosophy today. The frustrations, the stubborn facts and the curiosities of today’s thinkers, philosophers, physicists and psychologists, demonstrate the elusiveness, and the utter impenetrability of consciousness. Can we explain our perception of colour, smell or what it is like to be in love in purely physical terms? Can memory, conviction and reason be explained primarily in terms of neural firing sequences in the brain? Three centuries ago Descartes famously believed that the problem was best solved by being ignored. Was he right? Could it be that the human mind is just not built to understand its own basis?With Ted Honderich, philosopher and former Grote Professor of the Philosophy of Mind and Logic, University College, London; Sir Roger Penrose eminent physicist, mathematician and author of The Large, The Small, and the Human Mind.

Melvyn Bragg and guests discuss the theory of Genetic Determinism. In the middle of the last century two men - Gregor Mendel, an Austrian monk, and Charles Darwin, an English naturalist, established the central theories of modern biology and changed the world forever. Darwin’s On the Origin of Species has been described as the book of the Millennium, “the only best-seller to change man’s conception of himself”. Through the rediscovery of Mendel’s work in the early decades of our century, evolutionary theory was transformed by the emergence of genetics as a science. Crick and Watson found DNA at Cambridge and announced that they had discovered the secret of life in a local pub, and the rest has been the most compulsive element in the intellectual history of the twentieth century. It seems as if almost every week we read about another gene which claims to determine our fate - whether it governs our intelligence, personality or sexual orientation. Many rail against what they see as “genetic determinism” - the idea that genes are the destiny we can do nothing about. Others willingly blame their anti-social behaviour on “criminal genes” - thus absolving themselves of any responsibility. Genetics may be all about inheritance but is inheritance all about the genes? With Steve Jones, Professor of Genetics, University College, London and author of Almost Like a Whale: The Origin of Species Updated; Matt Ridley, science journalist, chairman of the International Centre for Life and author of Genome: The autobiography of a species in 23 chapters.

Melvyn Bragg and guests discuss pain; something of which everyone has an individual experience. What causes it, how do we cope with it, what mechanisms are involved, what is the traditional view of pain and how is that being challenged today? Do we experience pain in the same way and how is emotional pain different from physical pain? What can our experience of pain tell us about ourselves and human consciousness? Is each individual human experience unique or are there experiences we can say apply across all of human consciousness? Is science a blunt instrument for examining subjective experience?With Patrick Wall, Professor of Physiology at St Thomas’ Hospital, London and author of Pain: The Science of Suffering; Semir Zeki, Professor of Neurobiology at University College, London.
