Richard Wilson on the difference between doubt and dogmatism

Richard Wilson writes in the New Statesman about his new book "Don't get fooled again." From the piece:

In South Africa, at the beginning of this decade, Aids scepticism gained currency with a political class dismayed at the prices being charged for life-saving medicines. Under the influence of Duesberg and his fellow "dissidents", Thabo Mbeki's government chose to delay for several years public provision of anti-HIV drugs. The economist Nicoli Nattrass estimates that this decision - made amid one of the world's worst Aids epidemics - may already have cost hundreds of thousands of lives.
