Is this a “continental philosophers operating as normal before Wittgenstein” thing or is this a “Marx is particularly bad” thing?
The former (kind of - if memory serves, philosophers at least kept doing so after Wittgenstein). I am not at all calling Marx especially bad. Marx is singled-out because he’s important when it comes to topics related to socialism and, well, given who we are, he’s important when it comes to our views.
