In this essay on econometrics in its conception and its use in economic planning for the betterment of man's fate, I will try to cover a very broad field.
When talking about the methodology in the particular fields mentioned - about which I am supposed to have a little more than second hand knowledge - I have always found it utterly inadequate to focus attention only on these special fields without seeing them in a much broader perspective.
Therefore it was inevitable that I should have to include in the field of vision of this paper also some branches of science where I can only speak as a layman, hopefully as a somewhat informed layman. For whatever blunders I may have made in these fields I must ask for the reader's forgiveness
