Ich setze Mich nicht voraus, weil Ich Mich jeden Augenblick überhaupt erst setze oder schaffe, und nur dadurch Ich bin, dass Ich nicht vorausgesetzt, sondern gesetzt bin, und wiederum nur in dem Moment gesetzt, wo ich mich setze, d.h. Ich bin Schöpfer un Geschöpf in Einem.

I belong to no organized party. I am a Democrat.
Source: Will Rogers, Ambassador of Good Will, Prince of Wit and Wisdom (1935), Ch. 9 "Rogers was a lifelong Democrat but he studiously avoided partisanship. He contributed to the Democratic campaign funds, but at the same time he frequently appeared on benefit programs to raise money for the Republican treasury. Republican leaders sought his counsel in their campaigns as often as did the Democrats." ~ P. J. O'Brien
