A Research Report submitted to the Faculty of Humanities, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Master of Arts, Applied Ethics for Professionals, September 2017 / The cartoons depicting the Prophet Muhammad on the front cover of various issues of the French satirical magazine, Charlie Hebdo, leading up to the 2015 terrorist attack have been seen by many to be harmful and offensive. This report argues that, from a liberal perspective, the cartoonists did not do anything morally wrong by publishing these cartoons. In fact, it is argued that the cartoonists were morally justified in publishing these cartoons because they were protecting the liberal value of free speech. I argue that both the act of publishing these cartoons, as well as the actual content of these cartoons were morally justifiable. Arguments against the cartoons pertaining to both harm and offence are proven to be unsound. Furthermore, when balancing the seriousness of the offence with the reasonableness of the cartoons, it becomes clear that the offence is not as serious as some may think. / XL2018
