Is It Possible to Act Selflessly?

The following is my attempt to answer a question posed to me recently. When I look at the question, it seems to focus on the individual. So, I think the easiest way to begin this, is to start with the self. Since I’m no Derek Parfit or Bernard Williams, and the question seems to be focusing on moral sentiment and moral choice, I’m going to reduce the ‘self’ to just that part we always end up talking about, when we talk about choice: The Will.
