When asked by a reporter something like :"What, in your opinion is the most important question facing humanity today?" Einstein thought for a bit then replied, "I think the most important question facing humanity is, 'Is the universe a friendly place?' This is the first and most basic question all people must answer for themselves.
"For if we decide that the universe is an unfriendly place, then we will use our technology, our scientific discoveries and our natural resources to achieve safety and power by creating bigger walls to keep out the unfriendliness and bigger weapons to destroy all that which is unfriendly and I believe that we are getting to a place where technology is powerful enough that we may either completely isolate or destroy ourselves as well in this process.
"If we decide that the universe is neither friendly nor unfriendly and that God is essentially 'playing dice with the universe', then we are simply victims to the random toss of the dice and our lives have no real purpose or meaning.
"But if we decide that the universe is a friendly place, then we will use our technology, our scientific discoveries and our natural resources to create tools and models for understanding that universe. Because power and safety will come through understanding its workings and its motives."
