I'm an indoors person. I'm not afraid of the outdoors and I penetrate it easily and cheerfully. However, I must admit I like Central Park better than the wilderness, and I like the canyons of Manhattan better than Central Park, and I like the interior of my apartment better than the canyons of Manhattan, and I like my two rooms better with the shades down at all times than with the shades up. I'm not an agoraphobe at all, but I am a claustrophile, if you see the distinction.

Properly read, the Bible is the most potent force for atheism ever conceived.

I want to be a human being, nothing more and nothing less. ... I don't suppose we can ever stop hating each other, but why encourage that by keeping the old labels with their ready-made history of millennial hate?

I do not fear computers. I fear the lack of them.

You see, proteins, as I probably needn't tell you, are immensely complicated groupings of amino acids and certain other specialized compounds, arranged in intricate three-dimensional patterns that are as unstable as sunbeams on a cloudy day. It is this instability that is life, since it is forever changing its position in an effort to maintain its identity--in the manner of a long rod balanced on an acrobat's nose.

If a conclusion is not poetically balanced, it cannot be scientifically true.

The energy requirements for interstellar travel are so great that it is inconceivable to me that any creatures piloting their ships across the vast depths of space would do so only in order to play games with us over a period of decades. If they want to make contact, they would make contact; if not, they would save their energy and go elsewhere.
