Ever since the dawn of Enlightenment, toleration has been considered one of the most solid bastions of social peace in liberal and pluralist civilization. Acknowledging and protecting freedom of religion, ideas and speech, the modern rule of law can be considered as a political-institutional as well as juridical fulfillment of what previously was only a hoped-for virtue: toleration. What does tolerating those who are different, those who think or act differently, really mean? Is toleration a form of resignation and indifference regards to the mistakes of others? Or is it rather a synonym for respect for and interest in diversity? Who is called upon to be tolerant? Individuals or institutions?
