"But this madness has remained sane. The madness has remained sane when everything else went mad. The madhouse has been a house to which, age after age, men are continually coming back as to a home. That is the riddle that remains; that anything so abrupt and abnormal should still be found a habitable and hospitable thing. I care not if the sceptic says it is a tall story; I cannot see how so toppling a tower could stand so long without foundation. Still less can I see how it could become, as it has become, the home of man. Had it merely appeared and disappeared, it might possibly have been remembered or explained as the last leap of the rage of illusion, the ultimate myth of the ultimate mood, in which the mind struck the sky and broke. But the mind did not break. It is the one mind that remains unbroken in the break-up of the world. If it were an error, it seems as if the error could hardly have lasted a day. If it were a mere ecstasy, it would seem that such an ecstasy could not endure for an hour. It has endured for nearly two thousand years; and the world within it has been more lucid, more level-headed, more reasonable in its hopes, more healthy in its instincts, more humorous and cheerful in the face of fate and death, than all the world outside."
