7.4In this two-part Channel 4 series, Professor Richard Dawkins challenges what he describes as 'a process of non-thinking called faith'. He describes his astonishment that, at the start of the 21st century, religious faith is gaining ground in the face of rational, scientific truth. Science, based on scepticism, investigation and evidence, must continuously test its own concepts and claims. Faith, by definition, defies evidence: it is untested and unshakeable, and is therefore in direct contradiction with science. In addition, though religions preach morality, peace and hope, in fact, says Dawkins, they bring intolerance, violence and destruction. The growth of extreme fundamentalism in so many religions across the world not only endangers humanity but, he argues, is in conflict with the trend over thousands of years of history for humanity to progress to become more enlightened and more tolerant.

America is addicted to oil. President George Bush said so… and now that phrase is echoed everywhere. But are we really “addicted”? Our daily lives are dripping in oil. It’s in virtually everything we use and fuels everything we do. To be sure, it is something to worry about. Are we going to run out? Aren’t we fighting wars for oil? But, if we do slow the flow, how will that change the way we live? When it comes to what we’re told about oil, there’s rhetoric and then there’s reality. Who can we believe? The media? Politicians? Environmental activists? You’d be surprised. For nearly ten years, journalist turned media analyst MARK MATHIS has studied our use of oil. And what he found shocked him so thoroughly that he made a movie about the misinformation, distortions and even outright lies about oil. We do have an “oil problem” in America (and the world), but it’s not what you’ve been told. So, it’s time to Fill Up on Truth… for a change.
