As long as we do science, some things will always remain unexplained.

Subatomic particles do not exist but rather show 'tendencies to exist', and atomic events do not occur with certainty at definite times and in definite ways, but rather show 'tendencies to occur'.

The creativity and adaptability of life expresses itself through the spontaneous emergence of novelty at critical points of instability. Every human organization contains both designed and emergent structures. The challenge is to find the right balance between the creativity of emergence and the stability of design.

Genuine mental health would involve a balanced interplay of both modes of experience, a way of life in which one's identification with the ego is playful and tentative rather than absolute and mandatory, while the concern with material possessions is pragmatic rather than obsessive.

The more we study the major problems of our time, the more we come to realise that they cannot be understood in isolation. They are systemic problems, which means that they are interconnected and interdependent.

A diverse ecosystem will also be resilient, because it contains many species with overlapping ecological functions that can partially replace one another. When a particular species is destroyed by a severe disturbance so that a link in the network is broken, a diverse community will be able to survive and reorganize itself... In other words, the more complex the network is, the more complex its pattern of interconnections, the more resilient it will be.

Ecology and spirituality are fundamentally connected, because deep ecological awareness, ultimately, is spiritual awareness.
