"How to understand our cheerfulness. - The greatest recent event - that 'God is dead'; that the belief in the Christian God has become unbelievable - is already starting to cast its first shadow over Europe. To those few at least whose eyes - or the suspicion in whose eyes is strong and subtle enough for this spectacle, some kind of sun seems to have set; some old deep trust turned into doubt: to them, our world must appear more autumnal, more mistrustful, stranger, 'older'. But in the main one might say: for many people's power of comprehension, the event is itself far too great, distant, and out of the way even for its tidings to be thought of as having arrived yet."
