Over the past few years, many have asked me to clarify what I mean with self-sacrifice, as I have published about this, drawing upon my PhD study. Sometimes I feel that it is more urgent to explain what it is not and why I think it is a meaningful and relevant concept. I am afraid that those who ask a brief, clear cut answer, are let down. For my entire view everybody will need to read my book. But for those who want a first entry, I have created this page.
