Amartya Sen

Indian Modern · South Asia · born 1933

Indian economist and philosopher who holds that justice is about the real freedoms people have to live the lives they value.

What it is

Amartya Sen (born 1933) is an Indian economist and philosopher who won the Nobel Prize in Economics in 1998. He was born in Santiniketan in Bengal, and has taught in England and the United States since 1972, including at Harvard. He is known for asking a simple question about economics and justice: what are people actually able to do and to be?

His answer, the capability approach, says that a good society should be judged by the real freedoms its people have to live lives they have reason to value, such as staying healthy, learning, or having loving relationships. It reshaped how development is measured and informed the United Nations Human Development Report.

The main ideas

  • Capabilities. What matters is whether a person can actually be and do things they value, not only how much money or how many goods they have, or how happy they say they are.
  • People are different. The same resources do not do the same work for everyone. A person with a disability may need special goods to move around, and a pregnant woman has particular nutritional needs.
  • Adapting to hardship. People who live in harsh conditions may stop wanting what they can never have. Judging by satisfaction alone would then hide a lot of unfairness.
  • Real options matter. Someone who fasts by choice is in a different position from someone who starves, even if both go without food. The freedom to choose counts.
  • Against narrow utilitarianism. He criticised the form of utilitarianism behind welfare economics for judging actions only by their consequences, for looking only at subjective satisfaction, and for simply adding up totals.
  • Famine as a failure of distribution. He argued that famines are not caused only by a shortage of food but by who has the means to get it. He observed that no famine has taken place in a functioning democracy.

What it looks like in practice

Picture two towns with the same average income. In one, everyone has a clinic, a school and a bus that runs. In the other, the money is the same but there is no way to reach any of these. Sen would say the towns are not equal in what matters, and that the second needs more than money. This is an illustration of his line of questioning, not a passage from his writing.

Books and moments

  • "Equality of What?" (1979) is the essay that introduced the idea of capability.
  • Poverty and Famines: An Essay on Entitlement and Deprivation (1981) is his study of how famines happen.

Questions and criticism

  • Which capabilities count? If well-being is measured by capabilities, someone has to decide which ones matter, and it is fair to ask who decides.
  • Hard to measure. It is easier to count income than to count what people are able to do.
  • A paradox for liberals. His own result of 1970 shows that even mild demands for individual rights and agreement in preferences can clash when we try to combine everyone's choices into one.
