The Man Who Mistook His Wife’s Head for a Hat

The Man Who Mistook His Wife’s Head for a Hat

What happens when we are no longer able to recognise objects, but there’s nothing wrong with our ability to see? When we lose our sense of self and no longer feel the body we’re in? When the concept of ‘leftness’ is severed from our reality?

Oliver Sacks describes cases involving all these issues and more in a classic survey of ‘losses’ and ‘excesses’ in the human brain. The patients are a fascinating array of characters each suffering from such unusual problems that the symptoms seem almost comical. The eponymous man who failed to identify his wife’s head suffered from a form of visual agnosia , leaving him incapable of identifying objects, although his visual acuity was not impaired. Another sufferer had lost all ability to form new memories, and indeed was stuck at some point in his past, incapable of progressing past that point.

How Not to Be Wrong: The Power of Mathematical Thinking

How Not to Be Wrong: The Power of Mathematical Thinking

Maths is a powerful tool, but in the wrong hands it can be pointless at best, dangerous at worst. Unfortunately, most human beings are a wrong pair of hands. We weren’t designed for handling numbers of any complexity, and tend to be out of our depths once they go beyond single digits. But a basic knowledge of numbers makes us overconfident and keen to interpret figures and statistics we don’t really understand as if they were cold hard facts. You only need to watch someone trying to work out which packet of washing powder presents the better deal when the supermarkets add a few percentages to the labels, or our reactions to opinion polls or the latest cancer-scare headlines.

Wesley: The Story of a Remarkable Owl

Wesley: The Story of a Remarkable Owl

Doubtless recommended to me because I enjoyed Are We Smart Enough to Know How Smart Animals Are? by Frans de Waal, this story was at first somewhat disappointing in the sense that it is to a greater extent a personal memoir rather than an investigation of animal intelligence. I had been expecting a heavier, more science-laden account of their relationship, but once I’d adjusted to the style and tone of the book, I found plenty here to enjoy.

Return to Monolingualism

Return to Monolingualism

Over the years I’ve run through a number of plugins on this blog, many just for fun, adding non-essential little features for giggles or purely for show. Often the plugins run their course within a few years, going through a period of rising popularity with improvements, additions and occasional feature bloat, before ultimately overwhelming the poor one-man development band who subsequently goes silent and drops all support for their once pet project. Sometimes the functionality is superseded by happenings elsewhere – another plugin, an external service offering their own widgets, added functionality in the core – but othertimes the plugin just slumbers by the wayside and it falls to the community to pick up the pieces and carry on the torch.

Freedom Next Time

Freedom Next Time

What you need to know about humans is that they are dicks. And if you give them any power their dickness prevails over everything else.

That beautifully succinct phrase comes from a review  on Good Reads and is an understandable frame of mind to find yourself in after reading this book. Reading it ten years after publication, it’s almost surreal how little has changed in the intervening period, how the wheels of progress continue to grind on the gears of conservatism. In Freedom Next Time John Pilger surveys the state of peoples suffering under the weight of ignorance, ill-will, apathy and condescension in various theatres of the world, turning the spotlight in turn on Palestine, India, Afghanistan, South Africa and the Chagos Islands.
