The life of Jean-Dominique Bauby took a dramatic turn on Friday 8 December 1995. On that day, he had a cerebrovascular accident that left him in a coma. When he woke up twenty days later, his body did not respond, his brainstem was damaged beyond repair. Able to move only his left eyelid, Jean-Dominique patiently wrote a whole book, The Diving Bell and the Butterfly, where he describes his experience.

In essence, Intelligent Design claims to build on scientific observations. The rationale of the argument is that biological organisms, human beings in particular, are too complex to be the product of chance. They are designed. And if there is a design, there must be a designer.
If you have read George Orwell's novel Nineteen Eighty-Four, you will perhaps remember the fictive language Newspeak. By removing words from the English vocabulary, the powers that be gradually enclose the...
