In his own words:
"Urgent call for help against an attempt to censor my work.
I have received notification today that my recent 18-minute TEDx video presentation, “The War on Consciousness” (YouTube) which has at time of writing received more than 132,000 views, is to be deleted from the TEDx website because what I say in that presentation allegedly “strays well beyond the realm of reasonable science”, and because I allegedly make “non-scientific and reckless” statements about psychotropic drugs. I am fighting these charges from TED’s Science Board which in my opinion are untrue and amount to nothing more than an ideologically driven attempt to censor my work. All the indications, however, are that my presentation will be deleted some time today...
...I don’t intend to allow this bizarre transgression of my freedom of speech on the part of an institution – TED – for which I once had the highest respect, to pass without a fight..." (paraphrased)
Graham Hancock (born 2 August 1950 in Edinburgh, Scotland) is a British writer and journalist. Hancock specialises in unconventional theories involving ancient civilizations, stone monuments or megaliths, altered states of consciousness, ancient myths and astronomical/astrological data from the past. One of the main themes running through many of his books is the possible global connection with a "mother culture" from which he believes all ancient historical civilizations sprang.
Born in Edinburgh, Scotland, Hancock's formative years were spent in India, where his father worked as a surgeon. Having returned to the UK, he graduated from Durham University in 1973, receiving a First Class Honours degree in Sociology. As a journalist, Hancock worked for many British papers, such as The Times, The Sunday Times, The Independent, and The Guardian. He was co-editor of New Internationalist magazine from 1976–1979, and the East Africa correspondent of The Economist from 1981-1983. (Wikipedia)
