Let’s turn the kindness we show toward the stars to members of the human race on Earth and build up the trust and understanding between the different peoples and civilizations that make up humanity. But for the universe outside the solar system, we should be ever vigilant, and be ready to attribute the worst of intentions to any Others that might exist in space. For a fragile civilization like ours, this is without a doubt the most responsible path.

Look at them, the bugs. Humans have used everything in their power to extinguish them: every kind of poison, aerial sprays, introducing and cultivating their natural predators, searching for and destroying their eggs, using genetic modification to sterilize them, burning with fire, drowning with water. Every family has bug spray, every desk has a fly-swatter under it... this long war has been going on for the entire history of human civilization. But the outcome is still in doubt. The bugs have not been eliminated.

it is the nature of intelligent life to climb mountains. They all want to stand on ever higher ground to gaze ever farther into the distance. It is a drive completely divorced from the demands of survival. Had you, for example, been only concerned with staying alive, you would have fled from this mountain as fast and far as you could. Instead, you chose to come and climb it. The reason evolution bestows all intelligent life with a desire to climb higher is far more profound than more base needs, even though we still do not understand its real purpose. Mountains are universal and we are all standing at the feet of mountains.
