I mean, there's really not enough information there to respond to at all. Aristotle's discussion takes no account of the work he did as a practicing biologist because we're going to just assert that it didn't, and the result is flawed because it's flawed. I'd need to know more about precisely what he means by top-down and down-up too. Usually I associate that with holism vs. reductionism.
Oh, I very much agree that Clark seems to give short shrift to making it clear as to just 'how' Aristotle is flawed. At the moment, I can't verify exactly how Clark comes to his conclusion since it has something to do with a citation and reference he makes to an analysis made by Ernan McMullin in an essay from 1970 entitled,
The History and Philosophy of Science: A Taxonomy.
However, to me, it sounds like Clark is implying something resembling the concept of Heidegger's Hammer, I say this because in McMullin's essay I find that Aristotle's philosophical approach to science is compared, and said to be similar in some respects, to that of Rudolf Carnap, the analytic philosopher and logical positivist of the early 20th century who evaluated the practices of history and science. In fact, McMullin's evaluation is something like:
It is assumed by Aristotle and Carnap alike that one can make a sharp
cut between that which is to be proved or justified (what Carnap calls the
"hypothesis") and the evidence for it. The latter is supposed to be some-
how "given"; the concepts in which it is expressed are taken to be unprob-
lematic. Furthermore, no question is asked about how the hypothesis it-
self is derived in the first place, about the modifications of concept or the
postulates of structure that may have been needed in order to arrive at it.
In defense of so dubious a set of assumptions and so drastic a limitation of
goal, it is argued that only thus can purely logical modes of analysis be
used, and some over-all methodological pattern established.
(p. 13)
Then, following up from the previous quote I cited in the previous post above, I find Clark going on to say:
...Indeed, recent decades have witnessed a shift toward the historical approach [i.e. the Internal Method cited in my previous post, in contrast to the External Method]. In this method, researchers study how scientists actually do their work. The way successful scientists reason should guide philosophy of science. Leaders in this shift include Stephen Toulmin, Michael Polanyi, Ernan McMullin, and Thomas Kuhn. (p. 55)
That last name I'm sure you're familiar with.
And yes, all of this has something to do with holism versus reductionism.
Anyway, that smart alecky quip I made about Aristotle's
Posterior Analytics, I apologize for. That was all "me" saying that, quite apart from anything Clark was saying!
