What distinguishes the historical social system we are calling historical capitalism is that in this historical system capital came to be used (invested) in a very special way. It came to be used with the primary objective or intent of self-expansion. In this system, past accumulations were 'capital' only to the extend they were used to accumulate more of the same.
Immanuel WallersteinThe break from the supposedly culturally-narrow religious bases of knowledge in favor of supposedly trans-cultural scientific bases of knowledge served as the self-justification of a particularly pernicious form of cultural imperialism.
Immanuel WallersteinFor the other end of the spectrum, the 50 to 85 percent of the world's population who are not the recipients of privilege, the world they know is almost certainly worse than any their earlier counterparts knew. It is likely they are worse off materially, despite the technological changes. In substantive as opposed to formal terms, they are more, not less, subject to arbitrary constraints, since the central mechanisms are more pervasive and more efficient. And they bear the brunt of the various kinds of psychic malaise, as well as of the destructiveness of civil wars.
Immanuel WallersteinTo be sure, the use of force by one party in a market transaction in order to improve his price was no invention of capitalism. Unequal exchange is an ancient practice. What was remarkable about capitalism as a historical system was the way in which this unequal exchange could be hidden; indeed, hidden so well that it is only after five hundred years of the operation of this mechanism that even the avowed opponents of the system have begun to unveil it systematically.
