A couple of weeks ago, three excellent and interesting books came out in the same week with the same title. First was ‘Post Truth’ by Matthew D’ancona. The second one was ‘Post Truth’ by James Ball. The third was ‘Post Truth’ by Evan Davis. They are all responses to the Oxford English Dictionary’s decision to choose the word ‘post truth’ as their word for 2017 and the dangerous and growing phenomenon of ‘alternative facts’, ‘fake news’ etc. Here are a few thoughts of mine about the concept of ‘post truth’ based on these books and why the resultant erosion of trust is so dangerous for our society.
