Lasciate ogni speranza voi ch'entrate. Abandon all hope ye who enter here.

   Life is making us abandon established stereotypes and outdated views; it is making us discard illusions.

-Gorbachev, Mikhail Sergeyevich
  Speech, United Nations,7 Dec.

Ist es schwer und kann es ein AuÞenseiter begreifen,dass man eine Geschichte von ihrem Anfang in sich erlebt, vom fernen Punkt bis zu der heranfahrenden Lokomotive aus Stahl, Kohl und Dampf, sie aber auchjetzt noch nicht verl a« sst, sondern von ihr gejagt wird und aus eigenem Schwung vor ihr l a« uft, wohin sie nur st o« Þt und wohin man sie lockt. It is so difficult and can an outsider understand that you experience a story within yourself from its beginning, fromthe distant point up to theapproaching locomotive of steel, coal and steam, and you don't abandon it even now, but want to be pursued by it and have time for it, therefore are pursued by it and of your own volition run before it wherever it may thrust and wherever you may lure it.

-Kafka, Franz

Ce n'est pas assez pour moi de la posse¤  der,je veux qu'elle se livre. It's not enough to possess her. I want her to abandon herself.

Abandon yourself to Nature's truths, and let nothing in this world be unknown to you.
