Earlier this week, the American Enterprise Institute in Washington, DC, held a remarkably interesting conference titled "Panic Attack: The New Precautionary Culture, the Politics of Fear, and the Risks to Innovation." It was interesting not only because I was a participant, but because it looked at how many Western countries are losing their cultural nerve, as evidenced by the increasing cultural acceptance of the so-called precautionary principle.
Ron's perspective is, as usual, well worth noting. He doesn't deal specifically with nanotechnology in his essay, but CRN covers the topic in our paper, "Applying the Precautionary Principle to Nanotechnology."
