From the Quotation of the day mailing list, 2015-05-05:
"He who lives to see two or three generations is like a man who sits some time in the conjurer's booth at a fair, and witnesses the performance twice or thrice in succession. The tricks were meant to be seen only once, and when they are no longer a novelty and cease to deceive, their effect is gone." -- Arthur Schopenhauer, philosopher.
