The author argues that a correct approach to the question of tolerance cannot ignore the increasing importance of the religious factor on the political, cultural and social scene of the last few years. The common European model of the relationship between the State and religious faiths that may be called the Law possesses some margins of elasticity. These margins of elasticity may be defined as tolerance. A mechanism of selection allows the law to welcome those new requests for liberty that do not undermine the fundamental features of the model.
