I want to know the answer to the following question:
Who was one early naysayer of Humanism?
All the background I'm provided with is that "Postmodern critics who are self-described anti-humanists, such as Jean-François Lyotard and Michel Foucault, have asserted that humanism posits an overarching and excessively abstract notion of humanity or universal human nature, which can then be used as a pretext for imperialism and domination of those deemed somehow less than human.". Is that enough to answer the question?
Answer: no
