Discursive, entertaining and provocative, Secular Sermons contains fourteen essays by celebrated philosopher Professor Alan Musgrave, examining the basic assumptions of science, religion and mathematics. Can we decide what to believe? Why do scientists do experiments and wat can their experiments show? Is evolution a scientific theory? Such apparently simple questions are brilliantly investigated by Musgrave in order to interrogate the worldviews we inhabit - and their consequences. He brings to these questions an expansive historical knowledge, provoking his readers to enter the now-discredited belief-systems of earlier ages in order to compare these with their own.
