In “The Disremembered” Charles Leadbeater claims that “[p]hilosophy is not of much practical use with most illnesses but in the case of dementia it provides insights about selfhood and identity that can help us make sense of the condition and our own reactions to it.”  There are two broad philosophical explanations of self-identity. There is the mind-based or memory-based explanation of Descartes and Locke. But when mind and memory fade, so does self-identity. But there is another philosophical tradition that can help: “philosophers in this tradition contend that who we are depends not simply on our self-reflective ability to marshal our memories but, crucially, on our relationships with other people and how we are embedded in the world around us.” In other words, beware of being a memory snob.
