Instead, he is about to bash people who subscribe to 'new age' therapies which he says are based on 'irrational superstition'.

In a TV programme to be shown later this month, Dawkins looks at a range of ludicrous therapies and gurus, including faith healers, psychic mediums, 'angel therapists', 'aura photographers', astrologers and others. 

Not surprisingly, he is horrified by such widespread irrationality, not to mention an exploitative industry that fleeces people while encouraging them to run away from reality. He is right to be alarmed. 

What previously belonged to the province of the quack and the charlatan has become mainstream. The NHS provides funding for shamans, while the NHS Directory For Alternative And Complementary Medicine promotes 'dowsers', 'flower therapists' and 'crystal healers'. 

'We are living in a scientific, largely post-religious age in which faith is presented as unscientific superstition' 

Indeed, such therapies aren't the half of it. Millions of us are now eager to believe that the world is controlled by conspiracies of covert forces, for which there is not one shred of evidence because such theories are simply bonkers. 

Thus Press articles and TV documentaries seriously advance the belief that the 9/11 attacks on America were orchestrated by the U.S. government itself. Similarly, thousands believe that Princess Diana was murdered at the hands of a conspiracy composed of the Duke of Edinburgh, Prince Charles and MI5. 

Bestselling books by the former TV sports presenter David Icke, who has announced he is 'the son of God', argue that Britain will be devastated by tidal waves and earthquakes, and that the world is ruled by a secret group called the 'Global Elite' or 'Illuminati' which was responsible for the Holocaust, the Oklahoma city bombing and 9/11.

These trends are not just nutty but sinister. Thousands of cults now combine similar crazy beliefs with programmes to control people's minds and behaviour. 

Their techniques include food and sleep deprivation; trance induction through hypnosis or prolonged rhythmical chanting; and 'love bombing', where cult members are bombarded with conditional love which is removed whenever there is a deviation from the dictates of the leader.
