I am preparing the draft of a scientific article which greatly benefits from the well known quote:
"The whole is other than the sum of its parts"
However, I am unable to find the correct citation for it.
According to Wikipedia:
This principle maintains that when the human mind (perceptual system) forms a percept or "gestalt," the whole has a reality of its own, independent of the parts. The original famous phrase of Gestalt psychologist Kurt Koffka, "The whole is other than the sum of the parts" is often incorrectly translated[4] as "The whole is greater than the sum of its parts," and thus used when explaining gestalt theory, and further incorrectly applied to systems theory.[5] Koffka did not like the translation. He firmly corrected students who replaced "other" with "greater". "This is not a principle of addition" he said.[6] The whole has an independent existence.
To the best of my understanding, since I am using it as a quote, I am required to cite it. I have tried finding the source of the quotation using Google, but have been unsuccessful thus far. In such a scenario, is it appropriate to cite the 6th citation from the Wikepedia page, i.e,
Heider, F. 1977. Cited in Dewey, R.A. 2007. Psychology: An introduction: Chapter four - The Whole is Other than the Sum of the Parts. Retrieved 4/12/2014.
