I want to know the answer to the following question:
Why did Kari Marx criticize Humanist Philosophy's?
All the background I'm provided with is that "These ideas were challenged, for example by the young Karl Marx, who criticized the project of political emancipation (embodied in the form of human rights), asserting it to be symptomatic of the very dehumanization it was supposed to oppose.". Is that enough to answer the question?
