5 SDN’s philosophy We believe that every person and every living thing has inherent worth, and is owed respect and care. We believe that we live in an inter-dependent world, where we all belong and are enriched by each other’s contributions. We have always believed, since our beginnings in 1905, that the world can be a better and more equitable place, and that we can help to make it so. We believe that potentials and possibilities are realised when everyone offers and experiences care, connection and challenge.
