Tolerance emerged during the Modern Age as a response to the rise of Protestantism, aimed at preventing religious turmoil. Today, it reappears in the context of globalization, due to the rise of new religious and cultural minorities. Philosopher Salvatore Veca, by reinterpreting the history of the concept and the ideas of Voltaire and Rawls, explores the meaning of tolerance in contemporary society, affirming the need to reconceptualize it. The contemporary context presents new challenges that require reflection beyond the historical analysis. Veca identifies two main justifications for tolerance: the prudential justification, which considers tolerance as the result of a cost-benefit analysis, and the hermeneutic justification, based on the principle of fallibilism. Both of these views consider tolerance as an instrumental and contingent solution, but fail to offer a moral foundation. Veca's work aims to provide an ethical and political ground for tolerance presenting it as a public virtue. A world with diverse beliefs and lifestyles is not only ethically preferable but also conducive to human flourishing. As an ethical virtue, tolerance allows for coexistence, promotes understanding of different perspectives, and facilitates communication. Veca grounds this virtue on three key principles: authenticity, empathy and sympathy. Although Veca's proposal presents some challenges and problems, it attempts to rethink the concept of tolerance in the context of contemporary multiethnic society. His work offers valuable insights into how we can define intercultural and interreligious dialogue within a democratic framework, revisiting canonical arguments for tolerance while addressing the critiques on this principle.
