The manual on diversity has the goal to touch a number of components making part of a person’s identity. E. g. a person’s gender identity, religious or national ideologies, sexual orientation, disability, skin color, professional or other skills and other moral and material components that form diversity. Also discussed in the course of the manual are the topics of human relationships, approaches, worldviews, reality, conflict resolution, conflict sensitivity, and others. A few situations characteristic to our reality are touched. In the manual we can meet proposals acting as ways to improve human relationships.
