"With all kinds of clever inventions of comfortability, they want to teach people to make it as bright as possible around them in temporality so that they would no longer be able to see eternity. Or even if they do not want to do away completely with the conception of eternity and the happiness of eternity, they still want to degrade it in such a way that no eternal difference (indeed, can anything be more meaningless) remains between the temporal and the eternal. What difference, then, can remain? It seems to be beyond dispute that just as there is a difference of humanity between a human being and an animal, there must be an eternal difference between the temporal and the eternal."
