Though I can't fully answer Rich's objection, it made me think of Ted Hughes' short poem, "The Jaguar," which is available here. I'll just quote a few lines here:
But who runs like the rest past these arrives
At a cage where the crowd stands, stares, memerized,
As a child at a dream, at a dream, at a jaguar hurrying enraged
Through prison darkness after the drills of his eyes
On a short fierce fuse. Not in boredom -
The eye satisfied to be blind in fire,
By the bang of blood in the brain deaf the ear -
He spins from the bars, but there’s no cage to him
More than to the visionary his cell:
His stride is wildernesses of freedom:
The world rolls under the long thrust of his heel.
Over the cage floor the horizons come.
It’s possible to read Hughes’ poem as demystifying the "caged" jaguar, challenging our human-centric understanding: the jaguar doesn’t know what a cage is, and will never know. Hughes is getting us to see the world as (he presumes) the jaguar sees it, and as such is testing the limits of cognition. The poem can be read as complementary to the aims of science, in that it aims to get us to understand the jaguar's "being" as it really is, and not as simply a grumpy human-like thinking being that is gawked at by children, behind bars, in a zoo. To think of the animal as angry at its status, or bored, is to think metaphorically.
On the other hand, maybe not. Though the poem demystifies, when Hughes uses words like "freedom" and "anger" he also retains some level of anthropomorphism, and through anthropomorphism, metaphor. He probably couldn't successfully take us into the being of the jaguar in writing, or via any representation at all (the only way to really do that would be to become the jaguar).
What I was after in my previous post is the idea that scientists are as dependent on metaphor (especially the metaphor of anthropomorphism) as we are. They are, of course, not dependent on it when they are actively performing experiments; that is something else, and it doesn’t make sense to see it as connected to poetry at all. But the rest of the time, it seems to me that the attempt to comprehend and theorize requires metaphors.
If we grant that science depends on metaphors, it might also be possible to think of poems as doing something complementary to science: it might be possible to say from a linguistics point of view that a certain kind of poetry might perform conceptual tests on our understanding of what objects are in and through language. I think Hughes' poem attempts something like that, and succeeds in a very limited way.

As an example of a discussion of anthropomorphism within science itself, here are some comments by a computer science professor at UT-Austin:
Let me first relate my experience that drove home how pervasive anthropomorphism is. It took place at one of the monthly meetings of the science section of the Royal Netherlands Academy of Arts and Sciences, where we were shown a motion picture made through a microscope. Thanks to phase contrast microscopy . . . it is now possible to see through the microscope undied cultures of living cells, and that was what they had done while making this motion picture. It showed us - somewhat accelerated - the life of a culture of amoebae. For quite a while we looked at something we had never seen: I can only describe it as identifiable bubbles with irregular changing contours, slowly moving without any pattern through a two-dimensional aquarium. To all intents and purposes it could have been some sort of dynamic wallpaper. It was, in fact, rather boring, looking at those aimlessly moving grey blots, until one of the amoeba in the centre of the screen began to divide. We saw it constrict, we saw in succession all the images familiar from our high-school biology, we saw the centres of the two halves move in opposite directions until they were only connected by a thin thread as they began to pull more frantically at either end of the leash that still connected them. Finally the connection broke and the two swam away from each other at the maximum speed young amoebae can muster.
The fascinating and somewhat frightening observation, however, was that at the moment of the rupture one hundred otherwise respectable scientists gave all a sigh of relief: “at last they had succeeded in freeing themselves from each other." None of us had been able to resist, as the division process went on, the temptation to discern two individuals with which we could identify and of which we felt - more in our bones that in our brains, but that is beside the point - how much they “wanted” to get loose. A whole pattern of human desires had been projected on those blots! Crazy, of course, but such is the pervasive and insidious habit of anthropomorphic thought.
I thought this was interesting because Prof. Dijkstra makes it a point to describe the amoebae without any anthropomorphism at all in the first paragraph, and it’s purely abstract -— like looking at wallpaper. Then one of the other scientists in the room creates a human plot... and suddenly, it’s possible to “understand” it.
Whether or not I'm on the mark about the relationship between science and poetry, it's somewhat gratifying to see that scientists are interested in the problem of anthropomorphism as well.
