Physics and Philosophy (1958)
Context: [I]n the Copenhagen interpretation of quantum theory we can indeed proceed without mentioning ourselves as individuals, but we cannot disregard the fact that natural science is formed by men. Natural science does not simply describe and explain nature; it is part of the interplay between nature and ourselves; it describes nature as exposed to our nature of questioning. This was a possibility of which Descartes could not have thought, but it makes a sharp separation between the world and the I impossible.
If one follows the great difficulty which even eminent scientists like Einstein had in understanding and accepting the Copenhagen interpretation... one can trace the roots... to the Cartesian partition.... it will take a long time for it [this partition] to be replaced by a really different attitude toward the problem of reality. <!--p. 81

“Der erste Trunk aus dem Becher der Naturwissenschaft macht atheistisch, aber auf dem Grund des Bechers wartet Gott.” in 15 Jahrhunderte Würzburg: e. Stadt u. ihre Geschichte [15 centuries Würzburg. A city and its history] (1979), p. 205, by Heinz Otremba. Otremba does not declare his source, and the quote per se cannot be found in Heisenberg's published works.
The journalist Eike Christian Hirsch PhD, a personal acquaintance of Heisenberg, whom he interviewed for his 1981 book Expedition in die Glaubenswelt, claimed in de.wikiquote.org on 22 June 2015, that the content and style of the quote was completely foreign to Heisenberg's convictions and the way he used to express himself, and that Heisenberg's children, Dr. Maria Hirsch and Prof. Dr. Martin Heisenberg, did not recognize their father in this quote.
Statements similar to the quote were made by Francis Bacon, in "Of Atheism" (1601): "A little philosophy inclineth man’s mind to atheism; but depth in philosophy bringeth men’s minds about to religion", and Alexander Pope, in "An Essay on Criticism" (1709): "A little learning is a dangerous thing; drink deep, or taste not the Pierian spring: there shallow draughts intoxicate the brain, and drinking largely sobers us again."
There is a passage in a lengthy essay written by Heisenberg in 1942, "Ordnung der Wirklichkeit” ("Reality and Its Order"), published in Collected Works. Section C: Philosophical and Popular Writings. Volume I. Physics and Cognition. 1927-1955 (1984), that parallels the ideas expressed in the quote (albeit in a much expanded form):
"The first thing we could say was simply: 'I believe in God, the Father, the almighty creator of heaven and earth.' The next step — at least for our contemporary consciousness — was doubt. There is no god; there is only an impersonal law that directs the fate of the world according to cause and effect... And yet [today], we may with full confidence place ourselves into the hands of the higher power who, during our lifetime and in the course of the centuries, determines our faith and therewith our world and our fate." (English translation by M.B.Rumscheidt and N. Lukens, available at http://www.heisenbergfamily.org/t-OdW-english.htm)
Carl Friedrich von Weizsäcker, a protégé of Heisenberg, did publish a version of the quote itself in Die Geschichte der Natur (The History of Nature) (1948), appearing to consider it an adage:
"Aus dem Denken gibt es keinen ehrlichen Rückweg in einen naiven Glauben. Nach einem alten Satz trennt uns der erste Schluck aus dem Becher der Erkenntnis von Gott, aber auf dem Grunde des Bechers wartet Gott auf den, der ihn sucht. Wenn es so ist, dann gibt es einen Weg des Denkens, der vorwärts zu religiösen Wahrheiten führt, und nur diesen Weg zu suchen ist lohnend. Wenn es nicht so ist, wird unsere Welt auf die Religion ihre Hoffnungen vergeblich setzen." ("From thinking there is no honest way back into a naive belief. According to an old phrase, the first sip from the cup of knowledge separates us from God, but at the bottom of the cup God is waiting for the one who seeks him. If so, then there is a way of thinking that leads to religious truths, and to seek only that way is rewarding. If it is not so, our world will put its hopes to religion in vain.")
