The motive behind the tragic shootings at the headquarters of satirical weekly magazine Charlie Hebdo in Paris has not yet been confirmed but it seems clear that there is a link between the publication's stance on controversial content and the decision by several masked gunmen to launch such a murderous attack against the staff.
Now we must reaffirm the importance of absolute freedom of expression in an open society - regardless of how offensive it might be to some and, on occasion, how puerile it may become. The solution to bad ideas - as the enlightenment philosopher John Stuart Mill noted - is not censorship but more speech with which to counter them.
Charlie Hebdo has certainly been provocative in the past and hasn't relented in its approach since 2006, when it republished controversial cartoons depicting the prophet Mohammed, or since 2011 when its offices were fire bombed. Recent front covers have poked fun not just at the Muslim prophet, but the Pope, Jesus, Jews, various world leaders and celebrities. Infantile as some of this may seem, it is also a reaction to an increasingly censorious society.
While this attack and others like this shock the world, it is governments, as well as the media itself on occasion, that have been at the vanguard of banning free expression and regulating ideas in recent years. The French government has demonstrated its censorious and anti-Enlightenment outlook by banning Muslim women from wearing the veil in public, for example. Meanwhile, in the UK, the past year has seen an art exhibition in London shut down and a public debate on abortion cancelled at the University of Oxford.
In the wake of the Paris attack, it will be interesting to see how leaders react. Barack Obama, for instance, recently defended the right of film makers at Sony to poke fun at the North Korean President Kim Jong Un and accused North Korea of orchestrating a cyber-attack against the company in an attempt to stifle its freedom of expression. Whether or not he will be willing to come to the defence of Charlie Hebdo in such an absolute and uncompromising manner remains to be seen.
