the whole is greater than the sum of its parts is the motto of the
Gestalt psychology 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 something else than the sum of its parts"[2] is often incorrectly translated[3] 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.[4] Koffka did not like the translation. He firmly corrected students who replaced "other" with "greater". "This is not a principle of addition" he said.[5] The whole has an independent existence.
Consequentialism The phrase and concept of "The end justifies the means" are at least as old as the first century BC. Ovid wrote in his Heroides that Exitus acta probat "The result justifies the deed".
