The best part of a Reg Hartt presentation is what he has to say.

[Cities] are not like suburbs, only denser. They differ from towns and suburbs in basic ways, and one of these is that cities are, by definition, full of strangers.

Just the way in Europe, Paris, Copenhagen, and Stockholm, and Frankfurt, possibly and Berlin, certainly, all had important roles, because of independence. Because they were depending on themselves.

You can neither lie to a neighbourhood park, nor reason with it. 'Artist's conceptions' and persuasive renderings can put pictures of life into proposed neighbourhood parks or park malls, and verbal rationalizations can conjure up users who ought to appreciate them, but in real life only diverse surroundings have the practical power of inducing a natural, continuing flow of life and use.

...frequent streets and short blocks are valuable because of the fabric of intricate cross-use that they permit among the users of a city neighbouhood.

I think that intelligent people to a great extent are captives of their time or place.

The first fundamental of successful city life: People must take a modicum of responsibility for each other even if they have no ties to each other. This is a lesson no one learns by being told. It is learned from the experience of having other people without ties of kinship or close friendship or formal responsibility to you take a modicum of responsibility for you.
