Democracy is characterized by the recognition of individual value systems. Plurality of value systems is an inevitable condition. However, tolerance can lead to segmentation and even fragmentation when the focus of attention is limited to the search and recognition of individual demands, and not the common good. So, the main question of this article is: in the process of nurturing democracy and the commitment for tolerance, is it still possible for us to make room for various efforts to fight for the common good? To answer this question, the research method is a comparative literature review of the thought of David Hollenbach [1942-present] and comparing it with the encyclical Laudato Si [2015] of Pope Francis.

David Hollenbach argues that the fact of and the challenges of living together as global citizens make tolerance no longer sufficient as the only moral dimension of modern society. Hollenbach argues that tolerance still needs to be situated within the common endeavor to strive for the common good (bonum commune). Indeed, the basis of the search for the common good remains the respect for equality and freedom. These two values are strongly emphasized in tolerance. But equality and freedom need to be placed in a real challenge of living together that will inevitably force every citizen to be involved in finding solutions to it. According to Hollenbach, the Church's long tradition of reflecting on the common good (bonum commune) can contribute to efforts to integrate freedom and common endeavor in plural societies.

The collective action to save the environment guided by Pope Francis' encyclical Laudato Si is one example of reconciling tolerance and the common good. Its basis is ecological conversion that makes us more concerned about caring for creation. Ecological conversion initiated by the universal Church in cooperation with everyone of good will becomes a collective action to fight for bonum commune in a plural world.
