Pints and Philosophical Problems with Matthew Sweet. This week, the problem of induction: are we justified in predicting the future on the basis of what's happened in the past? How do we know that the sun will rise tomorrow? In the snug with Matthew is philosopher Helen Beebee, discussing a conundrum which faces all of us in our daily life - and which raises profound questions about the nature of science.
