That's often how such terms work.
I believe you're confusing values with structure. It's certainly true that corporations might be run differently, and that their management may espouse different values; but this doesn't alter a certain basic corporate model. Even when you say the "individual nature of people is diverse" while people are uniform in shape, you're making a false qualification; that is, you're saying that corporations (as far as this analogy goes) correspond to the intentions and will of the "people," which can be diverse. This is incorrect; the corporate model corresponds to the "uniform" model of the body.
So, you're correct to draw the distinction between human "nature" (I don't like this term, but I'll use it for sake of ease) and biological constitution; but you're wrong to draw the parallel between corporations and diverse human natures. Corporations, in this sense, must be compared in a material and structural sense to the "body"; after all, this is what the term translates into.
I think you are stopping short, or confusing what I mean here.
Different people have different values, specialties, methods etc. Of course there might be some relatively identical models here and there, and there will be overlap very often in any given area, but there is still a significant amount of uniqueness in behavior, despite humans having the same basic structure (organs, limbs, skeletal structure).
This is seen also in corporations, except that there are more variations in structure along with variations in values, specialties, methods, etc. You have basic legal differences like LLC, S, C, non-profit, etc. and then you also have structural differences within each of those, once the legal requirements for classification are met.
I don't mean any disrespect, but you're not really "in" either of those fields. I'm sure if you ask any of your philosophy professors about the antihumanist turn in later-20th-century philosophy, they would be able to explain it. More often than not this topic is reserved for more advanced philosophy courses since it isn't something that most find easy to grasp (I'm not saying it wouldn't be easy for you to grasp, just that most of the students in your courses would likely not find it accessible).
I am participating in scientific research within the social sciences, so I feel I can at least claim that. If you want to submit that social sciences aren't "real" science that is something else.
I also disagree about not being "in philosophy". However, given that due to scheduling all my classes and readings in school have been surrounding Ethics, it would indeed be unlikely to see anything antihumanist within Ethics classes, regardless of level.
Spam? Not at all; it's a metaphor for the exact opposite of consciousness. Spam consists of iterations with no discernible motive or intention toward interactive communication.
Think about how most people view spam; not as something profitable, even to those who perpetuate it and send it out. It's seen as a nuisance and as senseless, or even purposeless, since most people delete it or ignore it. On a vast popular scale, spam is a non-conscious entity.
You mentioned that it yields economic reward for those who send it; but that isn't how the metaphor works because that's not how the vast majority of people understand spam. Metaphors need not be logically correct; they're anything but logical. "My love is a red rose" contains nothing logical; the associations work because the phrase appeals to popular cultural knowledge. That's what Shaviro is commenting on, and that's why the spam metaphor does work.
I think people do understand spam that way, depending on its location. The spam in your mailbox is no different than what can wind up under your windshield wiper while you shop, or the posters slapped on every available surface in an urban area. To suggest that something ignored at any given juncture is purposeless is too obviously prey to reductio to bother with it. Defense of this position also appears headed straight for a No True Spam defense - as in if it is *not ignored/deleted/seen as a nuisance" by someone, then that particular instance is not spam. EG, The 1 out of 100 cases where someone clicks the spam.
Let us look at Facebook. People are FWDing this stuff for some personal reason, even as you and I want to claw our eyes out at the steady stream of "JESUS LOVES YOU - LIKE IF YOU AGREE", "SHARE THIS WITH TEN PEOPLE SO I CAN GO ON A TRIP", "LITTLE OLD LADY IS MUGGED - YOU WON'T BELIEVE WHAT HAPPENS", and so on. Is it spam or is it not spam? Looks pretty subjective to me. About as subjective as the opinion of Shaviro, or the opinion imaginary aliens in the story, etc.
