There is in this Universe much of what seems to be design.

Science is a way of thinking that helps you not to fool yourself.

There is a lurking fear that some things are not “meant" to be known, that some inquiries are too dangerous for human beings to make.

For years I've been stressing with regard to UFOs that extraordinary claims require extraordinary evidence.

Valid criticism does you a favor.

Imagine a room awash in gasoline, and there are two implacable enemies in that room. One of them has nine thousand matches. The other has seven thousand matches. Each of them is concerned about who's ahead, who's stronger. Well that's the kind of situation we are actually in. The amount of weapons that are available to the United States and the Soviet Union are so bloated, so grossly in excess of what's needed to dissuade the other, that if it weren't so tragic, it would be laughable. What is necessary is to reduce the matches and to clean up the gasoline.

If the greenhouse effect is a blanket in which we wrap ourselves to keep warm, nuclear winter kicks the blanket off.
