Foucault's claim on Marx and reference

“I often quote concepts, texts and phrases from Marx, but without feeling obliged to add the authenticating label of a footnote with a laudatory phrase to accompany the quotation. As long as one does that, one is regarded as someone who knows and reveres Marx, and will be suitably honoured in the so-called Marxist journals. But I quote Marx without saying so, without quotation marks, and because people are incapable of recognising Marx’s texts I am thought to be someone who doesn’t quote Marx. When a physicist writes a work of physics, does he feel it necessary to quote Newton and or Einstein?” (Foucault, Power/Knowledge, p. 52).

The interpretation of this quote demands a historical/cultural background in which this claim is made. Without this as the background, any attempt of interpreting this quote remains incomplete...
