Regulatory bodies, like the people who comprise them, have a marked life cycle. In youth they are vigorous, aggressive, evangelistic, and even intolerant. Later they mellow, and in old age – after a matter of ten or fifteen years – they become, with some exceptions, either an arm of the industry they are regulating or senile.
We forget that the water cycle and the life cycle are one.
Contingency is a thing unto itself, not the titration of determinism by randomness.
