The other day I lectured in Paris and after my lecture a very able man came to me and said, "Have you got a scheme?" I said, "What scheme?" "Of bettering conditions. " I replied that I had not made such a scheme, and he said, "I have a scheme, I will show it to you." He opened his box and brought out a very large paper with mathematics on it and showed it to me saying, "This is the economic scheme that will make the condition of the world better: everyone will have the same share." I said, "We should practice that economic scheme first on tuning our piano: instead of saying D, E, F, we should tune them all to one note and play that music and see how interesting that would be -- all sounding the same, no individuality, no distinction, nothing." And I added, "Economy is not a plan for construction, but it is a plan for destruction. It is economics which have brought us to destruction. It is the heart quality, it is the spiritual outlook which will change the world."
