Tolerance cannot not be concerned with the law, once it takes up in its concept the relationship between truth and justice. And there are several reasons for this. To begin with, the word right enters into many definitions of tolerance: the right to difference, to liberty, to those fundamental public freedoms that constitute human rights. Moreover, law, as opposed to morality, is the public instance where obligation is coupled with legitimate coercion. Finally, juridical institutions offer an excellent vantage point from which to observe the transformations of the idea of tolerance and scan the history of the struggles carried out in its name.
