To come back to my original question: is Marx relevant today? He is, if we understand his philosophy of history, which was his main interest and focus. He saw European capitalism and colonialism as universal, and originated a materialist view of history, a view that was Eurocentric–the spread of its political and economic enlightenment to the world. This view has influenced many thinkers after him–not all marxist as we understand the word–such as Wallerstein for example. It is necessary to understand Marx if we want to understand all economic theories of the 19-20th centuries, and study their development; it is necessary if we want to study where we stand ourselves after him, and if we take from him the undeniable continuity between the feudal to the modern order. If we recognize that the world in which we live today is the product of European/American economic imperialism (in whateever way we understnad this), then we may see in Marx one of the first to realize it. Even if few of us are Marxist in the sense we understand it, we are nonetheless influenced by his theories even today.
