In First Things, Peter J. Leithart reads Robert Pogue Harrison
What can make us at home again? Harrison quotes Heidegger's famous Der Spiegel interview in which he stated that “only a god can save us.” The interviewers responded to Heidegger's insistence that human beings are essentially related to earth (humans to the humus) by proposing that human beings are not determined by anything at all. One day, they said, we may settle on other planets and then where, Prof. Heidegger, is your humus human?
Humans need to get essentially related to the sky -- continue the discoveries; go where no anthropos has gone before -- because the sun's going to fry the earth some day. And who's going to save us from large, extinction event, meteorites?
