A wisdom deficit - fewer elders and even fewer people who listen to them.

I pictured myself as a virus or a cancer cell and tried to sense what it would be like.

I see the triumph of good over evil as a manifestation of the error-correcting process of evolution.

Life is an error-making and an error-correcting process.

There is a moment of conception and a moment of birth, but between them there is a long period of gestation.

A wisdom deficit - fewer elders and even fewer people who listen to them.

If all the insects were to disappear from the earth, within 50 years all life on earth would end. If all human beings disappeared from the earth, within 50 years all forms of life would flourish.
