Peter Singer’s Drowning Child thought experiment

In 1971, the region that is now Bangladesh fought for independence from Pakistan. At the time, Peter Singer was a philosophy lecturer at the University of Oxford.

Horrified by the suffering in Bangladesh, Singer wrote an essay in which he put forward his Drowning Child thought experiment, one of the most influential ideas in modern philosophy.

The thought experiment, published in 1972, inspired the Effective Altruism movement, which has led donors to commit billions of dollars to charities. Peter Singer speaks to Ben Henderson.

This programme contains views on disability that some people may find offensive.
