Friedrich Nietzsche said this quote

“ And that discovery would betray the closely guarded secret of modern culture to the laughter of the world. For we moderns have nothing of our own. We only become worth notice by filling ourselves to overflowing with foreign customs, arts, philosophies, religions and sciences: we are wandering encyclopaedias, as an ancient Greek who had strayed into our time would probably call us. But the only value of an encyclopaedia lies in the inside, in the contents, not in what is written outside, in the binding or the wrapper. And so the whole of modern culture is essentially internal; the bookbinder prints something like this on the cover: “Manual of internal culture for external barbarians.” The opposition of inner and outer makes the outer side still more barbarous, as it would naturally be, when the outward growth of a rude people merely developed its primitive inner needs. For what means has nature of repressing too great a luxuriance from without? Only one,—to be affected by it as little as possible, to set it aside and stamp it out at the first opportunity. And so we have the custom of no longer taking real things seriously, we get the feeble personality on which the real and the permanent make so little impression. Men become at last more careless and accommodating in external matters, and the [Pg 34] considerable cleft between substance and form is widened; until they have no longer any feeling for barbarism, if only their memories be kept continually titillated, and there flow a constant stream of new things to be known, that can be neatly packed up in the cupboards of their memory. ”
