In 1999 the BBC conducted a series of polls, asking people to name the
greatest men and women of the millennium. In October of that year,
within a few weeks of the tenth anniversary of the dismantling of the
Berlin Wall, the BBC declared the people's choice for “greatest
thinker”. It was Karl Marx. Einstein was runner-up, Newton and Darwin
third and fourth, respectively. “

In a poll of eliciting 34,000 votes to a UK radio programme for the
greatest philopher, Marx came far ahead of rivals with 28% of the
vote.

Double that of the next rival David Hume at 13%
The interesting thing was in Eric Hobsbawm's observations on the
result - available on the internet.
