I have been charmed and delighted to find that the comments that have come in for this series have been sound, friendly, helpful and informed. In this final episode for this series, I’ve singled out one or two. Thank you for your questioning, your listening — go on searching, asking and wondering. Wondering in both senses: wondering by wanting to know and wondering by marvelling. And here’s to madmen, hermits, heretics, dreamers, rebels and sceptics.
