But that does stop his rumination about Heidegger scholars, what I take it to be meant by cult:
There is also something interesting to be written about the ways in which the Heidegger cult and its temporal and cultural kin, the Strauss cult, have operated in similar, quasi-fascistic, "in group" vs. "out group" ways: esoteric terminology, hostility towards dialectic engagement, worship of the master, and so on.
Heidegger doesn't engage in dialectical argument because for him, the purpose of philosophy is to describe human facticity. He is teasing out phenomenological descriptions of human existence. Maybe that is, in itself, an argument---yet in so doing, philosophy is not a description of some problem abstracted from history. It occurs within an ontotheology. In this way, it is resistant to the very positivism that carries Leiter's naturalistic Nietzsche (of course, I would argue something like that someday)! This is not some weird obscurantism if people were honestly going to give him an honest reading, know the background of the philosophy that gives birth to Heidegger, i.e. Husserl, know his contemporaries like Natorp, the background of Dilthey, and see him as completing (by Heidegger's self-estimation) the shortcoming of Husserl's phenomenology. When you know all of that, Heidegger is up to something whether or not one agrees with its status in the history of phenomenology, or philosophy at large.
Moreover, understanding the context of Heideggerian phenomenology in its beginning allows one to encounter why Heidegger moves to poetry. In fact, the language Heidegger adopts is provocative; it has a purpose beyond the lens put to language in any analytic framework. But again, one would have to understand the under-currents of Rilke, Holderlin, Heidegger's rejection of some central themes of the metaphysics of presence and the attempt to implement phenomenology as reasons for why Heidegger requires/uses language the way he does.
The charitability of Leiter's lapse is as charitable as a Protestant Minister's characterizing Leiter's work on moral psychology and Nietzsche. Just because Heidegger and those influenced by his philosophy look like something from the outside doesn't mean they are that way. This is a separate issue from whether or not Continental philosophers and supporters of Heidegger in general have done a good job of talking to outsiders. However, the outsiders must be willing to listen, and one good way might be to honestly represent Continental philosophy schools that are marginalized. And, I might add, have great scholars in phenomenology working on Heidegger! But this problem is more complicated than just than the professional dimension.
Leiter also displays some ignorance of the status of this debate. Consider the following,
"Faye's leitmotif throughout is that Heidegger, from his earliest writings, drew on reactionary ideas in early-20th-century Germany to absolutely exalt the state and the Volk over the individual, making Nazism and its Blut und Boden ("Blood and Soil") rhetoric a perfect fit." OK, so how do these "reactionary ideas" about exaltation of "the state and the Volk" figure in the main themes of Being and Time? I have no idea...
Since Leiter finds the argument from one phrase of Romano on Faye somewhat "interesting", let's look at the above. First, this theme has already been taken up by a number of skeptics and critics. The big book, Mr. Leiter is Victor Farias' Heidegger and Nazism. So, now you have some "idea"; you're only about twenty years too late in your ignorance (It was published in 1987 by Temple University Press).
Really... Oh yes, he does Continental philosophy lady and gentleman. Lest we forget. Now, I know he is nice to me when he says, "The ideas that Heidegger's books should be banned and that anyone who studies Heidegger is a Nazi sympathizer are so ludicrously offensive as to defy belief." I take that as nice, and what he might mean by generous. But seriously, you have to listen to people, like myself, who engage in this stuff before characterizing us from the outside. At least, he goes to Thomson and Carman as good philosophers working on phenomenology. At least, we should respect him that far. Yet, the spirits of his comments are redolent of generosity cloud in the intolerance we Continental Philosophers (Aspiring or Established) find ourselves.
