Amartya Sen's Inequality Re-Examined is a seminal text setting out a theory to evaluate social arrangements and inequality. By asking the question, 'equality of what'?, Sen shows that (in)equality should be assessed as human freedom; for people to have the ability to pursue and achieve goals they value or have reason to value.

The text lays out the fundamental ideas to Amartya Sen's Capability Approach. This approach is celebrated in diverse academic disciplines because of its specific contribution towards the improvement to debates on inequality beyond economic deprivation and utility measures. Furthermore, the arguments put forward by Sen in Inequality Re-Examined has had many practical applications throughout policy circles including the Human Development Index, the Multi –Dimensional Poverty Measure, the compilation of lists of capabilities and drawing further attention to human agency and democracy. Amartya Sen won the Nobel Prize for Economics in 1998 for his contribution to welfare economics; the core arguments of this work is found in this book.
