“When philosophizing,” Ludwig Wittgenstein writes, “one has to climb down into old chaos and feel well there”. In philosophizing, the human subject touches chaos, the non-ground. It maintains an at least problematic contact with it. To feel well in chaos can mean nothing other than to integrate the uncanny, the incommensurable and unviable dimension which it represents into one’s way of living. To feel well in chaos is tantamount inhabiting an uninhabitable region or, assimilating oneself to that which is most disturbing.
