Creativity is a spark. It can be excruciating when we're rubbing two rocks together and getting nothing. And it can be intensely satisfying when the flame catches and a new idea sweeps around the world.
...new ideas are merely several old thoughts that occur at the exact same time.
Just because an idea is true doesn't mean it can be proved. And just because an idea can be proved doesn't mean it's true.
[It's] troubling because it reminds us how difficult it is to prove anything. We like to pretend that our experiments define the truth for us. But that's often not the case. Just because an idea is true doesn't mean it can be proved. And just because an idea can be proved doesn't mean it's true. When the experiments are done, we still have to choose what to believe.
Cities force us to interact with strangers and with the strange. They pry the mind open. And that is why they are the idea that has unleashed so many of our new ideas.
