The Invisible Gorilla by Christopher Chabris and Daniel Simons challenges many preconceptions about our certainties of the world. The subtitle, And Other Ways Our Intuitions Deceive Us, describes what the book is all about: how we can be lured into a false sense of believing ourselves correct in many aspects of our lives. The authors describe the fragility of memory; how recall seems to us like an unedited video, but is instead a continuously updated and altered process with errors added all the time. We should never be certain of past events unless there is robust corroboration. Professors admanant they knew exactly where they were when the Twin Towers were attacked were mistaken. Eye-witness testimonies taken very soon after events can differ remarkably. The examples go on.
After reading The Invisible Gorilla I now preface every statement involving memory with a comment along the lines of “As far as I recall”. So when I say that, as far as I recall, the last thing I remember before regaining conciousness in the Emergency Department was seeing a car heading straight towards me and thinking “I’m not certain that car should be there,” I might be mistaken. However this is the image that still wakes and haunts me in the early lonely hours.

We like to think of time as linear. Seconds building on seconds, forming the minutes, hours and days that track the path of our lives. Dementia and death fracture this line.





Adelaide Martens was born in London in 1845, the daughter of a sugar baker. There is little known of her early years, but when she was 17 she decided to emigrate to the antipodes. She obtained work as a stewardess and sailed to Australia, then on to New Zealand. While working as a stewardess on coastal boats between Invercargill and Christchurch she met Henry Hicks, a cook and steward on the same ship. His mother was English, and his father a freed Afro-American slave. Adelaide and Henry were married in Invercargill and moved to Dunedin, to live in Leith Street.
