Is there such a thing as the self? If so, what is it? We all have experience of having or being a self, a hidden inner mental presence. Galen Strawson argues that if we look closely at what experience of a self is like, we may be able to work out what a self must be, if it exists. He concludes that selves do exist, but they are not what we think. Selves is a wonderfully engaging and provocative book. True, it is long, often complex, and sometimes dense and difficult, with many by-ways and detours en route to its astonishing conclusion - but it is also bold, brilliantly written, and packed full with insights, arguments and speculations.
