I’ve just finished reading An Anthropologist on Mars, by Oliver Sacks. It is a compilation of case studies of people with neurological disorders, how it affects their memories, their creativity and their life in general, and how they create new senses of self.

As I mentioned in another thread, it is quite interesting, but it is not light reading. I’ve just spent a couple of weeks reading with a dictionary by my side.

Here are the words I had to look up. There's no need for anybody to comment, I'm just putting them here because I found them interesting and I though you might too.

Qualia: n. The experiences of sensory input (as opposed to the describable facts of such input.) In the classic example, a sighted person can see red, (e.g. “red looks hot”) or provide informational descriptions (e.g. “it’s the colour you see when light of such-and-such wavelength is directed at you”.) Simpler still, consider the impossibility of ever describing the experience of seeing colour to a person born blind.
