Understanding is a delaying tactic. - Michael Crichton

All major changes are like death. You can't see to the other side until you are there.

To an outsider, the most significant innovation in the global warming controversy is the overt reliance that is being placed on models. Back in the days of nuclear winter, computer models were invoked to add weight to a conclusion: “These results are derived with the help of a computer model.” But now, large-scale computer models are seen as generating data in themselves. No longer are models judged by how well they reproduce data from the real world—increasingly, models provide the data. As if they were themselves a reality. And indeed they are, when we are projecting forward.

My own sense is that the acquisition of self knowledge has been made difficult by the modern world. More and more human beings live in vast urban environments, surrounded by other human beings and the creations of human beings. The natural world, the traditional source of self-awareness, is increasingly absent.
