The supreme good lies in the integrity of the earthly and cosmic community, which at this phase of evolution is entrusted to human responsibility. Human beings live ethically when they maintain the dynamic equilibrium of all things and when, in order to preserve it, they prove capable of setting limits to their own desires. Human beings are not simply beings of desires; desire alone would make them anthropocentric and mimetic. They are also and fundamentally beings of solidarity and communion. When they become more so, they enter into harmony with the universal dynamism and carry out their cosmic mission as custodian, troubadour and guardian angel for everything crated, thereby realizing their ethical dimension.

— Leonardo Boff, Cry of the Earth, Cry of the Poor
