言論自由的爭論，自始常和政治與宗教牽扯。2015年初法國「查理事件」引發的爭議－言論自由與宗教信仰孰輕孰重，若從法國歷史文化脈絡中理解，與「世俗性」（laicite）原則脫不了關係，亦即與宗教信仰在法國社會中被賦予之社會功能和所代表的意義息息相關。本文即針對何謂「世俗性」原則；「世俗性」是否等同於「言論自由」；既受到法國世俗傳統的影響，「言論自由」在法律保障下，如何看待宗教表述；另外，言論自由保障下的「嘲諷權」與「傷害言論」，該如何區隔；以及法律是解決或深化仇恨，且實踐上是否會引發倫理道德爭議等各面向，試從法律觀點逐一檢視。

Freedom of expression is considered the most significant characteristics of a liberal society, while it's often in conflict with religion and politics. In early 2015, a huge controversy was raised in the wake of the tragic attack on French satirical magazine Charlie Hebdo: where to draw the line concerning freedom of expression and religion? In France, the answer can only be found through reference to French laicite (＂secularism＂). This paper will try to clarify the meaning and function of the principle and how it is applied to freedom of expression and religion issues. Inevitably, it will distinguish between the legal parody as a form of free speech and hate speech, to know whether the law could resolve disputes or deepen prejudice.
