Lionel Windsor formerly worked as a photovoltaics engineer at a solar cell research company. He is now an ordained Anglican minister, lecturing in New Testament at Moore College in Sydney. He is the author of Is God Green? and Gospel Speech Online.

"In this book Lionel Windsor shows his characteristic clarity and thoughtfulness as he helps us understand life in a post-truth generation. I like the way Lionel approaches social media not as a dinosaur, scoffing that life was somehow so much better back in his day, but instead recognising that every new technology gives the world new opportunities and new challenges.
"Lionel has a gift for making complex philosophies accessible. Throughout the book Lionel gives us great short summaries of some very complex ideologies that have shaped of our age. But by far the greatest advantage of this book is that it reminds us that the gospel sits at the centre of all truth and that the gospel alone is the way to fix our truth problem."
