Rebuttal and Surrebuttal

Image result for neurons


I will continue here the trend of thought of my recent posts about Fiona Cowie's 1999 book, What's Within. It criticizes both Fodor and Chomsky in some detail and I've already paraphrased/summarized her take on Fodor. 

But in a sense the continuation is a pause. Instead of going further, into the part of the book that discusses Chomsky's linguistics views, I'll look a bit further at the differences between Fodor and Cowie as they have played themselves out SINCE the publication of this book.


Fodor himself replied at length to Cowie, in an essay called Doing Without What's Within.


It is a lengthy essay and difficult to summarize. Here is a link to the whole thing, for this who want to pursue this jousting. Fodor Strikes Back.


Quite early on in this essay, Fodor suggests that the relationship between empiricism and rationalism, or innatism, as classically understood, was symmetrical -- and that Cowie wrongly re-imagined it as asymmetrical so that she could claim that the empiricists had won it. In Fodor's symmetrical rendering, the problem with the old debate was that "nativism is merely the denial of empiricism insofar as we lack a way of saying what `innate’ comes to other than not learned. Likewise, empiricism is merely the denial of nativism insofar as we lack a way of saying what `learned’ comes to other than not innate."


Cowie puts the burden on nativists "to say exactly what doctrine they're endorsing," keeping the empiricists off that hook. Neither when discussing classical philosophers nor when expressing her own views, Fodor charges, does Cowie ever say what she means by learning.  She makes, he says, "occasional references to connectionism as possibly an alternative to Chomsky's rationalism," but even so connectionism doesn't come up in relation to Fodor himself, and her occasional references to it fall far short of endorsement.


Connectionism in the relevant sense is the view expounded by Rumelhart and McClelland that looks at learning neurologically, working from the way that (quoting R & M here) artificial simulated neurons can be "linked to each other through weighted connections representing synapses or groups thereof." Cowie cites it briefly in her book as one of the developments in computer science that "promises us machines that can more naturally implement the 'softer' constraints of probabilistic learning processes." 

Fodor had had previous runs-ins with connectionists -- he believed it was a trend that was undoing progress that had been made in AI research. So he was clearly unhappy about Cowie's references, however slanting.  

Anyway: let us pause there and turn to Cowie's surrebuttal. 


She actually concedes something to the point I just cited Fodor as making. She writes, 


"I admit that the position I called Enlightened empiricism – the potential alternative to nativism that What’s Within argues had been unfairly ignored by nativists and empiricists alike – was not adequately discussed in the book. This was a mistake, and if I had it to do over again, I'd do it differently. In any case, I now have a chance to say a little more about how Enlightened empiricism is supposed to work, and I trust that by doing so, I can make clear why Fodor's objections to the position in his §2.3.3 are premature."


Here's the link for the whole discussion:

Her idea of "enlightened empiricism" is the  view that growing children learn language through hypothesis testing, that there are constraints at any given time on the range of possible hypothesis, but that these constraints are determined NOT by innate equipment but by the state of her opinion at an earlier time, t-1. 


A three year old child inherits preconceptions, then, not from an immortal reborn soul or from the genetically determined wiring of the brain, but from the two year old child.  The connectionist model may have something to do with this. It is not the neural equipment we are born with, but how it grows during the years that we're learning language, that is of momentous importance here.

A Story About Coleridge

This is a quote from a memoir by Dorothy Wordsworth, reflecting on a trip she took with two famous poets, her brother, William Wordsworth, and their similarly gifted companion, Samuel Taylor Coleridge.   We sat upon a bench, placed for the sake of one of these views, whence we looked down upon the waterfall, and over the open country ... A lady and gentleman, more expeditious tourists than ourselves, came to the spot; they left us at the seat, and we found them again at another station above the Falls. Coleridge, who is always good-natured enough to enter into conversation with anybody whom he meets in his way, began to talk with the gentleman, who observed that it was a majestic waterfall. Coleridge was delighted with the accuracy of the epithet, particularly as he had been settling in his own mind the precise meaning of the words grand, majestic, sublime, etc., and had discussed the subject with William at some length the day before. “Yes, sir,” says Coleridge, “it is a maj...

The Lyrics of "Live Like You Were Dying"

Back in 2004 Tim McGraw recorded the song "Live Like You were Dying." As a way of marking the one-decade anniversary of this song, I'd like to admit that a couple of the lines have confused me for years. I could use your help understanding them. In the first couple of verses, the song seems easy to follow. Two men are talking, and one tells the other about his diagnosis. The doctors have (recently? or a long time ago and mistakenly? that isn't clear) given him the news that he would die soon. "I spent most of the next days/Looking at the X-rays." Then we get a couple of lines about a man crossing items off of his bucket list. "I went sky diving, I went rocky mountain climbing, I went two point seven seconds on a bull named Fu Man Chu." Then the speaker -- presumably still the old man -- shifts to the more characterological consequences of the news. As he was doing those things, he found he was loving deeper and speaking sweeter, and givin...

Five Lessons from the Allegory of the Cave

  Please correct me if there are others. But it seems to be there are five lessons the reader is meant to draw from the story about the cave.   First, Plato  is working to devalue what we would call empiricism. He is saying that keeping track of the shadows on the cave wall, trying to make sense of what you see there, will NOT get you to wisdom. Second, Plato is contending that reality comes in levels. The shadows on the wall are illusions. The solid objects being passed around behind my back are more real than their shadows are. BUT … the world outside the the cave is more real than that — and the sun by which that world is illuminated is the top of the hierarchy. So there isn’t a binary choice of real/unreal. There are levels. Third, he equates realness with knowability.  I  only have opinions about the shadows. Could I turn around, I could have at least the glimmerings of knowledge. Could I get outside the cave, I would really Know. Fourth, the parable a...
