"Cities are the crucible of human civilization, the drivers towards potential disaster, and the source of the solution to humanity's problems. It is therefore crucial that we understand their dynamics, growth and evolution in a scientifically predictable, quantitative way. The difference between 'policy as usual' and policy led by a new quantitative understanding of cities may well be the choice between creating a “planet of slums” or finally achieving a sustainable, creative, prosperous, urbanized world expressing the best of the human spirit."
ps. Keep that in mind. But, remember not to take it as a mantra.
