To cope with the problems of today's world, we need to enter into a dialogue regardless of political, religious and philosophical beliefs - a transversal dialogue as Pope Francis called for in the private audience, he gave to Alexis Tsipras, Walter Baier and Franz Kronreif in September 2014. This conversation resulted in the DIALOP initiative - a transversal dialogue between Socialists and Christians. Since then, a network of universities and NGOs have been exploring paths of what they call a transversal social ethics. In this book authors from Austria, Belgium, Colombia, France, Germany, Greece, Hungary, Italy, Portugal and the Vatican air their views on topics like social equality, European Unity, democracy, the commons and ecology. The editors are the steering committee of the initiative DIALOP - transversal dialogue project.
