When the Nobel award came my way, it also gave me an opportunity to do something immediate and practical about my old obsessions, including literacy, basic health care and gender equity, aimed specifically at India and Bangladesh.
It is also very engaging - and a delight - to go back to Bangladesh as often as I can, which is not only my old home, but also where some of my closest friends and collaborators live and work.
From the mid-1970s, I also started work on the causation and prevention of famines.
But the idea that I should be a teacher and a researcher of some sort did not vary over the years.
People's identities as Indians, as Asians, or as members of the human race, seemed to give way - quite suddenly - to sectarian identification with Hindu, Muslim, or Sikh communities.
I left Delhi, in 1971, shortly after Collective Choice and Social Welfare was published in 1970.
