This article argues that secularism is not neutral. Secularization is a process, the secular state is a structure, whereas secularism is a political philosophy. Secularism takes two main forms: first, a “benevolent” secularism that endeavours to treat all religious and nonreligious belief systems even-handedly, and, second, a “hostile” kind that privileges unbelief and excludes religion from the public sphere. I analyze the European Court of Human Rights decision in Lautsi v Italy, which illustrates these types. The article concludes that secularism as a political philosophy cannot be neutral, and the secular state is not neutral in its effects, standpoint, governing assumptions or treatment of religious truth claims.
