Take an incisive look at Buddhism's past, present, and future.

Faced with the spectacle of the cruelties perpetrated in the name of faith, Voltaire famously cried ‘Ecrasez l’infâme!’. Scores of enlightened thinkers followed him, declaring organised religion to be the enemy of mankind, the force that divides the believer from the infidel and which thereby both excites and authorises murder. Richard Dawkins is the most influential living example of this tradition, and his message, echoed by Dan Dennett, Sam Harris and Christopher Hitchens, sounds as loud and strident in the media today as the message of Luther in the reformed churches of Germany. The violence of the diatribes uttered by these evangelical atheists is indeed remarkable. After all, the Enlightenment happened three centuries ago; the arguments of Hume, Kant and Voltaire have been absorbed by every educated person. What more is to be said? And if you must say it, why say it so stridently? Surely, those who oppose religion in the name of gentleness have a duty to be gentle, even with – especially with – their foes?

The God Delusion by the atheist writer Richard Dawkins, is remarkable in the first place for having achieved some sort of record by selling over a million copies. But what is much more remarkable than that economic achievement is that the contents – or rather lack of contents – of this book show Dawkins himself to have become what he and his fellow secularists typically believe to be an impossibility: namely, a secularist bigot. (Helpfully, my copy of The Oxford Dictionary defines a bigot as ‘an obstinate or intolerant adherent of a point of view’).
