The public realm in America has two roles: it is the dwelling place of our civilization and our civic life, and it is the physical manifestation of the common good. And when you degrade the public realm, you will automatically degrade the quality of your civic life and the character of all the enactments of your public life and communal life that take place there. The public realm comes mostly in the form of the street in America because we don't have the 1,000-year-old cathedral plazas and market squares of older cultures. And your ability to define space and to create places that are worth caring about all comes from a body of culture that we call the culture of civic design. This is a body of knowledge, method, skill and principle that we threw in the garbage after World War II and decided we don't need that anymore; we're not going to use it. And consequently, we can see the result all around us. The public realm has to inform us not only where we are geographically, but it has to inform us where we are in our culture. Where we've come from, what kind of people we are, and it needs to, by doing that, it needs to afford us a glimpse to where we're going in order to allow us to dwell in a hopeful present.
