The only reason runaway global warming seems unstoppable is that we have not yet tried to stop it.

A spacecraft is a metaphor of national inspiration: majestic, technologically advanced, produced at dear cost and entrusted with precious cargo, rising above the constraints of the earth. The spacecraft carries our secret hope that there is something better out there-a world where we may someday go and leave the sorrows of the past behind. The spacecraft rises toward the heavens exactly as, in our finest moments as a nation, our hearts have risen toward justice and principle.

I think the thing that I most appreciate now is that stereotypes involving Jewish identity activate fears of persecution that exist in the present day.

Instant-doomsday hyperbole caused the world's attention to focus on the hypothetical threat of global warming to the exclusion of environmental menaces that are real, palpable, and awful right now.

Set aside the many competing explanations of the big bang; something made an entire cosmos out of nothing. It is this realization - that something transcendent started it all - which has hard-science types... using terms like "miracle."

Stereotypes involving Christian identity, Christian persecution is so far back in history now that no one fears it being revived, unless you live in China, I guess.

We must use the smartest possible economics, and that means investing in China and India.
