Abstract
This book investigates the idea of inequality. According to the author, it does not address the question whether one should care about inequality nor which version is more plausible. Instead, its purpose is “to understand egalitarianism”, to “elucidate the notion of inequality”. The general thesis is that inequality is a “complex notion,” as shown by the fact that there are many different ways of measuring it. This is relentlessly detailed in a series of chapters that many will find rather hard on the brain, with their panoplies of diagrams and technical distinctions, complete with acronyms. Still, the diagrams are clear enough, and the terminology to the point.
