"Society is more than a number of individuals. It is a number of individuals among whom certain definite and more or less stable relations exist."
"In possessing use value a commodity is in no way peculiar. Objects of human consumption in every age and in every form of society likewise possess use value. Use value is an expression of a certain relation between the consumer and the object consumed. Political economy, on the other hand, is a social science of the relations between people."

Paul Marlor Sweezy was an American Marxist economist, political activist, publisher, and founding editor of the long-running magazine Monthly Review. He is best remembered for his contributions to economic theory as one of the leading Marxian economists of the second half of the 20th century.
"Society is more than a number of individuals. It is a number of individuals among whom certain definite and more or less stable relations exist."
"It seems obvious that in this way the economist avoids a systematic exploration of those social relations which are so universally regarded as having a relevance to economic problems that they are deeply imbedded in the everyday speech of the business world. And it is even more obvious that the basic point of view which modern economics has adopted unfits it for the larger task of throwing light on the role of the economic element in the complex totality of relations between man and man which make up what we call society."
"The legitimate purpose of abstraction in social science is never to get away from the real world but rather to isolate certain aspects of the real world for intensive investigation."
"Discussions of methodology in economics, as in other fields, are likely to be tiresome and unrewarding. Nevertheless, to avoid the problem altogether is to risk serious misunderstanding."
"It must be emphasized, because the contrary has so often been asserted, that Marx was not trying to reduce everything to economic terms. He was rather attempting to uncover the true interrelation between the economic and the non-economic factors in the totality of social existence."
"The real danger from advertising is that it helps to shatter and ultimately destroy our most precious non-material possessions: the confidence in the existence of meaningful purposes of human activity and respect for the integrity of man."
