World history is tragic.

What the world needs is not redemption from sin but redemption from hunger and oppression; it has no need to pin its hopes upon Heaven, it has everything to hope for from this earth.

To not be afraid in our world is the message that doesn't derive from reason, but maybe from this mysterious capacity given to humans which we call--not without a little embarrassment--faith.

The planet on which we live is poorly organized, many areas are overpopulated, others are reserved for a few, technology's potential is only in part realized, and most people are starving.

Our science has become terrible, our research dangerous, our findings deadly. We physicists have to make peace with reality. Reality is not as strong as we are. We will ruin reality.

There are risks which are not acceptable: the destruction of humanity is one of them

Do we still have the right to be more than victims?
