Scratch the surface of knowledge and mystery bubbles up like a spring. And occasionally, at certain disquieting moments in history (Aristarchus, Galileo, Plank, Einstein), a tempest of mystery comes rolling in from the sea and overwhelms our efforts.

A lifetime in front of a TV set may be the equivalent of a self transplant.

The dark night was the first book of poetry and the constellations were the poems.

The new advocates of ID [Intelligent Design] ask that their ideas be judged by scientific, not religious, criteria. OK, let's see how well ID stacks up as a scientific alternative to Darwinism. To gauge how well ID is doing as a platform for scientific research, I logged into the best database of the biological literature. A search for keyword ''evolution'' yielded 24,000 hits in the last decade. A search for ''intelligent design'' yielded not a single piece of research. Evolution by natural selection remains the basis of every successful biological research program.

Knowledge is an island surrounded by a sea of mystery.

I am a cautious pilgrim of the night, a tentative wanderer among the stars. My awareness of my home in the universe is fleeting and incomplete. Into the homeless home of the sun-faced buddha I have stepped but briefly.
