"No, nothing is sacred. And even if there were to be something called sacred, we mere primates wouldn't be able to decide which book or which idol or which city was the truly holy one. Thus, the only thing that should be upheld at all costs and without qualification is the right of free expression, because if that goes, then so do all other claims of right as well."

The history of intellectual growth and discovery clearly demonstrates the need for unfettered freedom, the right to think the unthinkable, discuss the unmentionable, and challenge the unchallengeable. To curtail free expression strikes twice at intellectual freedom, for whoever deprives another of the right to state unpopular views necessarily also deprives others of the right to listen to those views.
