The following paper is a reply to Vernon Ruttan's article "The Sociology of Development and Underdevelopment: Are There Lessons in Economics'?", which is an attempt to point out the potential contributions of sociologists utilizing modernizalion theory, dependency theory and world systems theory to economics. The argument put forth in this paper is basically a partial agreement of Ruttan's comment that communication between economists and sociologists has become rare. However, the paper explains this barrier by emphasizing three points. First. that sociology has developed into a decreasingly systematic, flexible discipline. Second, it has adopted various and differing theoretical paths which co-exist as accepted epistemological modes. Three, sociology has forcefully rejected the Parsonian project to codify and systematize the discipline within a structural-functionalist approach. The conclusion made is thal inevitably, any socio-cultural explanation of variations in econoinic change is bound to disrupt the very explanatory framework proposed by economics.
