Fear comes from uncertainty. When we are absolutely certain whether of our worth or worthlessness we are almost impervious to fear.

Fundamentalists are panicked by the apparent disintegration of the family the disappearance of certainty and the decay of morality. Fear leads them to ask if we cannot trust the Bible what can we trust?

The best thing about science is that hard empirical answers are always there if you look hard enough. The best thing about religion is that the very absence of that certainty is what requires - and gives rise to - deep feelings of faith.

I'm a scientist not a theologian. I don't know if there is a God or not. Religion requires certainty. Revere and respect Gaia. Have trust in Gaia. But not faith.

When prayer removes distrust and doubt and enters the field of mental certainty it becomes faith and the universe is built on faith.

Faith means living with uncertainty - feeling your way through life letting your heart guide you like a lantern in the dark.

Our nation's Social Security Trust Fund is depleting at an alarming rate and failure to implement immediate reforms endangers the ability of Americans to plan for their retirement with the options and certainty they deserve.

Life is full of change and uncertainty. We know this. We experience it on a daily basis.
