Dr. Gumplowicz, professor of sociology at the University of Gratz, says that there are illusions which have been most baneful in the wider life of the world. He mentions two of them which, with real German facility for coining new names, he calls "acrochronism" and "ethnocentrism." ["Address of Professor J.C. Bracq," in "The Eighth Lake Mohonk Arbitration Conference," May 28, 1902; he adds, "Acrochronism is the illusion which leads us to think that what we are doing is the culminating point of some great process."]

I am grown old and my memory is not as active as it used to be. When I was younger I could remember anything, whether it had happened or not; but my faculties are decaying now and soon I shall be so I cannot remember any but the things that never happened. It is sad to go to pieces like this, but we all have to do it. [Mark Twain, "Autobiography"]
