Towns

We begin with that part of the language which defines a town or community. These patterns can never be “designed” or “built” in one fell swoop but patient piecemeal growth, designed in such a way that every individual act is always helping to create or generate these larger global patterns, will, slowly and surely, over the years, make a community that has these global patterns in it.
