Arthur Chester Millspaugh, a US citizen, is well known in the modern political history of Iran due to his two consultancy missions for financial and monetary reforms in Iran (in 1922 and 1943). Having experienced the colonial behavior of Britain and Russia, Iranians preferred to employ foreign experts from countries with no colonial recording Iran, such as the US, France, Germany, Austria and Italy. This paper, by reviewing two books by Millspaugh, The American Task in Persia and Americans in Persia. Will present a different perspective on such missions. Powerful colonial states, as a result of uneven relationships, look at colonized countries from subjects' point of view, and their studies are based on subject/object relationships. In those studies, subjects employ their own standards to study others, and leave no room for objects' standards to play in the cognition process. As a step towards critical review of western Iranology, this article will study MiIlspaugh's books' to recognize subject /object perspective and relationship in these studies. This study will conclude the necessity of developing appropriate for social and cultural needs and conditions.
