JETZT tries to tell the history of thought in a poetological way. Human being in relation to nature and his surrounding is in constant change. Man is re-inventing himself again and again by inventing new descriptions of himself and his surrounding. By those descriptions we can observe the changes in the past human history. It’s the transformation of language use through human history which is the subject matter of this opera. Seven epochs are chosen. Short scenes about death interconnect those seven epochs.
