Peter Sloterdijk said this quote
“ The stakes in this game are not low. Our enterprise is no less than the introduction of an alternative language, and with the language an altered perspective, for a group of phenomena that tradition tended to refer to with such words as 'spirituality', 'piety', 'morality', 'ethics' and 'asceticism'. If the manoeuvre succeeds, the conventional concept of religion, that ill-fated bugbear from the prop studios of modern Europe, will emerge from these investigations as the great loser. Certainly intellectual history has always resembled a refuge for malformed concepts - and after the following journey through the various stations, one will not only see through the concept of 'religion' in its failed design, a concept whose crookedness is second only to the hyper-bugbear that is 'culture'. ”
