In the year of the bicentenary of Karl Marx's birth, the historian José Neves addresses the complex legacy that the philosopher left us, a legacy that did not pass the test of time or the ups-and-downs of political and economic history. He talks of what is still current – and often such an integral part of current language and representations of the political and social world that we all seem to be more or less Marxians, even if we are not Marxists.
