Everything that happens in life is there to aid our spiritual growth.
It is our task-our essential, central, crucial task-to transform ourselves from mere social creatures into community creatures.
We cannot solve life's problems except by solving them.
We know a great deal more about the causes of physical disease than we do about the causes of physical health.
Integrity is never painless.
The major threats to our survival no longer stem from nature without but from our own human nature within. It is our carelessness, our hostilities, our selfishness and pride and willful ignorance that endanger the world.
