Yes well it has to do with relevance and providing compelling descriptions of our intellectual milieux. I don't think the Republicans are master deconstructionists, but they sure are adept at manipulating the media, and thus the critique of the right and especially the cabal calls for sophisticated arguments. The notion that the American moron represents the current incarnation of the totalitarian masses does not strike me as adroit. However, Arendt's work does strike a chord, and your observations are insightful. I'll return to that after fielding some of your particular questions.
1. You obviously have a passing familiarity with semiotics, but I would now strongly recommend reading Roland Barthes'
Mythologies. The ideas are clearly presented, the examples are both illuminating and humorous, and the prose is enjoyable, even in translation. If you were to draw one idea from it, iirc, you'd probably be struck by the argument about how
contextualization confers meaning. To put it crudely, for example, when you want to understand what a particular example of photojournalism is saying, you don't merely look at what's in the photo: you look at what the photo is in. That's too crude, but you get the picture.
2.
Bruno Latuour, the nonmodernist. Very interesting, especially from the point of view of the theory of science. Thanks for pointing him out. I have never understood the fascination with Michel Serres. Perhaps in time.
3. Neo-Kantians and the field of cognitive science. Okay, I have some familiarity with the work of Mark Johnson who worked with Lakoff. I think that's valuable work, especially with regards to the science of language, but I don't see it as a validation of Kant, and viewed in the context of other ideas about language, it's not the be all and end all for me. Your primary concern is epistemology and scientific theory? I can see how you would prefer Kant to say Foucault. Well, there have been accomplishments in cognitive science but the essential claims seem overreaching and unconvincing to me--viewed within the whole of linguistics and philosophy etc.
4. Psychological insights. Well, among other things, I guess so, yes. Speaking of the lives of thinkers, you might be interested in Kristeva's
Hannah Arendt: Life is a Narrative. Or if you're going to deal with the Heidegger question, also
The Political Ontology of Martin Heidegger by Bourdieu. These things are related, and postmodernism encompasses some of that kind of critique, but there are important distinctions to be drawn. The question of Heidegger's political life wouldn't deserve much consideration if it weren't for the fact that he was an existential phenomenologist, and not just any existentialist, but a leading proponent and an institutionally well-positioned and influential mentor. So there are deeply philosophical grounds for investigating the personal lives and politics of the existentialists, and you see that beginning with Sartre, Merleau-Ponty, Levinas, and of course Arendt, who imo is the person who wrestled most with this conflict and offered the most profound resolutions.
There is another angle on the personal exposed by the postmodernists proper, which has to do with the rejection of master narratives and decentering the locus of ideation and hence shifting the focus of inquiry away from the cogito, and in some manifestations of that approach you see like Guattari's notion of schizo:
A long time ago I renounced the Conscious-Unconscious dualism of the Freudian topoi and all the Manichean oppositions correlative to Oedipal triangulation and to the castration complex. I opted for an Unconscious superposing multiple strata of subjectivication, heterogeneous strata of variable extension and consistency. Thus a more "schizo" Unconscious, liberated from familial shackles, turned more towards actual praxis than fixations on, and regressions to, the past. An Unconscious of Flux and abstract machines rather than an Unconscious of structure and language. I don't, however, consider my "schizoanalytic cartographies" to be scientific theories. Just as an artist borrows from his precursors and contemporaries the traits which suit him, I invite those who read me to take or reject my concepts freely. The important thing is not the final result but the fact that the multicomponential cartographic method can co-exist with the process of subjectification, and that a reappropriation, an autopoeisis, of the means of production of subjectivity can be made possible.
(From Chaosmosis, "On the Production of Subjectivity," pp. 12-13.)
I don't expect that you'll be too receptive at this point, but I think you can see the seductiveness of the approach here, and maybe see why it resonates with the experience of intellectual life for many of us, especially those of us outside the strictures of established disciplines.
5. Philosophy is dead? On the contrary, postmodernism ("") has given us a wealth of new thinking and provided some of the best minds of our time the opportunity to flourish. In my book, Derrida, Lyotard and Kristeva are genuine philosophers doing genuine work with genuine talent.
6. Rorty is indeed eddifying--when he's not floundering around unsure of where to apply his thinking. There is a deep connection with Arendt's politics of pluralism, but of course stylistically they are not close. Hopefully recent events will push Rorty to a stronger examination of his pluralism and the pragmatic. (I know he's been critical of Bushco, and also certain intellectual (non)responses, but I'm waiting for something more in depth.) And I think the distiction you are making between eddifying and structural I have read for instance in one of his defences of Derrida. It is worth looking at.
7. Back to Baudrillard. I'm reading over
Simulations now. First, an explanation of what is meant by the age of Simulation:
In this passage to a space whose curvature is no longer that of the real, nor of truth, the age of simulation thus begins with a liquidation of all referentials--worse: by their artificial resurrection in systems of signs, a more ductile material than meaning, in that it lends itself to all systems of equivalence, all binary oppositions and all combinatory algebra. It is no longer a question of imitation, nor of reduplication, nor even of parody. It is rather a question of substituting signs of the real for the real itself, that is, an opperation to deter every real process by its opperational double, a metastable, programmatic, perfect descriptive machine which provides all the signs of the real and short-circuits all its vicissitudes. Never again will the real have to be produced--this is the vital function of the model in a system of death, or rather of anticipated resurrection which no longer leaves any chance even in the event of death. A hyperreal henceforth sheltered from the imaginary, and from any distinction between the real and the imaginary, leaving room only for the orbital recurrence of models and the simulated generation of difference. (pp.3-4)
On a theoretical level, the allusion is to Levi-Strauss, and what you have is a turning of structuralism on its head with Benjamin as the fulcrum. Well, as I said, Barthes offers the kindest introduction here, and Baudrillard's use of Benjamin is transparent enough.
Ah, but the application. Can you see the potential? There are some decent examples presented by Buadrillard, for instance in the latter half of the book he discusses opinion polling. He presents a thesis like opinions are no longer formed or produced, but instead are subject to an endless reproduction, a kind of political hyperreality.
The polls manipulate that which cannot be decided. Do they really effect the vote? True, false? Do they give an exact picture of reality, or simple tendencies, or the refraction of this reality in a hyperspace of simulation whose curve even is unkown? True, false, undecidable. Their most sophisticated analyses leave room always for the reversibility of the hypotheses. Statistics is only casuistry. This undecidable quality is proper to any process of simulation (see above, the crisis of indecision). The internal logic of these procedures (statistics, probability, operational cybernetics) is certainly rigorous and "scientific"; somehow though it does not stick, it is a fabulous fiction whose index of refraction in any reality (true or false) is nil. This is even what gives these models their forcefulness. But it also is this which only leaves them, as truth, the paranoid projection tests of a case, or of a group which dreams of a miraculous correspondance of the real to their models, and therefore of an absolute manipulation.
What is true of the statistics scenario is also true of the regulated partition of the political sphere: the alternation of the forces in power, majority/minority, substitutive, etc. On this limit of pure representation, "that" no longer represents anything. Politics die of the too-well-regulated game of distinctive oppositions. The political sphere (and that of power in general) becomes empty. This is somehow the payment for the accomplishing of the political class' desire: that of a perfect manipulation of social representation. Surreptitiously and silently, all social substance has left this machine in the very moment of its perfect reproduction.
The same thing holds true for the polls. The only ones who believe in them finally are the members of the political class, just as the only ones who really believe in advertising and market studies are the marketeers and advertisers. This is not because they are particularily stupid (though we can't exclude that either) but because the polls are homogeneous with the current functioning of politics. They take on a "real" tactical value, they come into play as a factor in the regulation of the political class according to its own rules of the game. It therefore has reason to believe in them, and it believes. But who else does, really? It is the political class' burlesque spectacle, hyperrepresentative of nothing at all, that people taste by the way of the polls and media. There is a jubilation proper to spectacular nullity, and the last form it takes is that of statistical contemplation. This is accompanied always, we know, by a profound disappointment--the kind of disillusion that the polls provoke in absorbing so utterly the public's voice, in short-circuiting all process of expression. The fascination they exercise is in accordance with this neutralization by emptiness, whith this trance they create by anticipation of the image over all possible reality. (pp. 126-129, the Semiotext(e) edition btw, and do read further, it's interesting.)
Whew.
Okay. To sum up where I'm coming from. No doubt Arendt is a superior thinker with some insights on the origins of totalitarianism, and as you have pointed out, she remains very much relevant. What I'm saying is not that you should drop Arendt in favor of Baudrillard. Far from it. But I do think Braudillard's description of mass representations rings true in many ways. If your task is avowedly political, then I don't see any reason why you shouldn't consider other versions of the story of wholesale duplicity and bring them to bear on your critique of PNAC propoganda. After all, you're not necessarily aiming to construct a foundational system for explaining political discourse. Take a cue from Rorty. If it's eddifying, go for it.
