The authentic spiritual quest is marked not by certainties but by questions and doubt. How To Be An Agnostic explores the wonder of science, the ups and downs of being ‘spiritual but not religious’, the insights of ancient philosophy, and God the biggest question. Mark Vernon was an Anglican priest, left a conviction atheist, and now finds himself to be a committed, searching agnostic. Part personal story, part spiritual search, this journey through physics and philosophy concludes that the contemporary lust for certainty is demeaning of our humanity. We live in a time of spiritual crisis, but the key to wisdom – as Socrates, the great theologians and the best scientists know – is embracing the limits of our knowledge. This much expanded edition was previously published as After Atheism, and includes new chapters looking at mindfulness meditation, pic’n’mix religion, quantum spirituality, the probability of God and why Stephen Hawking is wrong about nothing.
