It is clear that the nations of the world now can only rise and fall together. It is not a question of one nation winning at the expense of another. We must all help one another or all perish together.

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

If we continue to accumulate only power and not wisdom, we will surely destroy ourselves.

Except in pure mathematics, nothing is known for certain (although much is certainly false).
Carl Sagan

Any faith that admires truth, that strives to know God, must be brave enough to accommodate the universe.
