The Potsdam Denkschrift is a declaration of Hans-Peter Dürr, J. Daniel Dahm and Rudolf zur Lippe under the patronage of the Federation of German Scientists-VDW. It is the base – the “mother” of the abstract condensed version, the Potsdam Manifesto ‚We have to learn to think in a new way’ what was up to now signed by more than 130 scientists and personalities from all over the world. Both were presented to the public in Berlin in autumn 2005. The collapse of a course of action legitimised by the materialistic-deterministic world view of the classical physics is elucidated in several chapters. The "progressing uniformity of all ideas of value and affluence, habits of consumption and economic strategies on the pattern of a Western/American/European knowledge society" (Potsdam Manifesto & Potsdam Denkschrift) and its hazards is accentuated and a rethinking towards a more holistic view and behaviour is claimed. Creativity, differentiation and connectedness are basic characteristics of life. The future is essentially open. Process For the initiation, scientific feedbacking in content and composition and for the multiplication of Potsdam Denkschrift & Potsdam Manifesto an intensive international scientific discourse was carried out since beginning of the Einstein-Year 2005. An interdisciplinary symposium in Potsdam to discuss a first draft of the “Denkschrift” (therefore Potsdam Denkschrift & Potsdam Manifesto) was carried out in June 2005. The resultant development of the critical and bracing symposium was the full backing of all participants, as well as the decision to publish a short Manifesto additionally to the “Denkschrift”. On October 14, 2005 both - the short Potsdam Manifesto 2005 "We have to learn to think in a new way" and the more explicit Potsdam Denkschrift 2005 - were presented to the public in Berlin. In the following months various international signees of the Potsdam Manifesto were contacted and successfully mobilized as supporters. Background Denkschrift and Manifesto connect to a central but not expanded appeal of the Russell–Einstein Manifesto of Bertrand Russell and Albert Einstein, published on the 9th of July 1955 in London: "We have to learn to think in a new way". The Russell–Einstein Manifesto was an ultimate calling for a new way of thinking that would guarantee war, in the future, to be completely banned as an instrument of politics and conflict resolution.
