I’ve met author and assisted-death advocate Terry Pratchett twice, both times years ago before he began to suffer from posterior cortical atrophy, a rare form of early-onset Alzheimer’s. He is one of the scariest-clever people I’ve ever had the privilege to converse with. I’m not a total moron, and fairly un-used to feeling like one in company, but Pratchett along with my old friend Charlie Stross and Richard Dawkins are three who manage it effortlessly.
If you haven’t read Pratchett’s books – humorous fantasy but with a darkness and an ascerbic wit most reminiscent of George MacDonald Fraser’s Flashman series, I heartily recommend them. But whether you’re new to his work or an old fan, you really should read the interview by Laurie Penny currently at The New Statesman.
