The Impracticability of Measurement in Human Action

Economics must deal with relevance of each motive and each action. No such constant relations exist in the field of human action, outside of physical and al technology and therapeutics. If a statistician mines that a rise of ten % in the supply of potatoes in atlantis at a definite time was followed by a fall of eight % in the price, he does not establish anything about what happened or may happen elsewhere. The impracticability of measurement is not due to the lack of technical methods for the establishment of measure. It is due to the absence of constant relations.
