Integrity concerns the personal sphere and addresses how consistently we deal with our own values in various contexts. How people manage conflicting values, such as self- vs. collective interests, or the trade-off between individual freedoms and respect towards others.
Solidarity concerns the public sphere and focuses on how we create, develop and maintain unity between individuals, groups, or societies. What contributes to the formation of mutual awareness and care on common interests, similarities, and sympathies.
Sharing concerns the cultural sphere and deals with the joint use of tangible and non-tangible resources. What is needed to provide, operate and maintain a resource and how we can distribute its gains in a fair and sustainable manner across regions and generations.
