Is this a true of false quote?

If we study the course of our cultural life during the last twenty-five years we shall be astonished to note how far we have already gone in this process of retrogression. Everywhere we find the presence of those germs which give rise to protuberant growths that must sooner or later bring about the ruin of our culture. Here we find undoubted symptoms of slow corruption; and woe to the nations that are no longer able to bring that morbid process to a halt.
