Vitality and beauty are gifts of Nature for those who live according to its laws.

If we approach nature and the environment without this openness to awe and wonder, if we no longer speak the language of fraternity and beauty in our relationship with the world, our attitude will be that of masters, consumers, ruthless exploiters, unable to set limits on their immediate needs. By contrast, if we feel intimately united with all that exists, then sobriety and care will well up spontaneously.

I am against nature. I don't dig nature at all. I think nature is very unnatural. I think the truly natural things are dreams, which nature can't touch with decay.

The majority of people living on our planet profess to be believers. This should spur religions to dialogue among themselves for the sake of protecting nature, defending the poor, and building networks of respect and fraternity.

The wisest and noblest teacher is nature itself.

Experiment is the sole interpreter of the artifices of Nature.
