Dave Weinberger types out of a drug- and fatigue-induced haze:

Truth is a property of networks.

I can only guess at what I mean, starting with the obvious: Rather than thinking that truth is a relationship between the propositions we believe and the way the world is, such that the propositions represent the world, in the networked world the truth is argued for and connected via links. For all but the most mundane of truths, the network of conversations gives us more shades, nuances, and reasons to believe. Which leads me to think that if truth isn’t an emergent property of networks, then understanding is.

I think he’s right, except it’s not either/or: it’s both.
