Daniel Dennett's Darwin Day Delivery

As I mentioned on Pharyngula, I was invited by a philosopher friend to attend the Darwin Day talk by Daniel Dennett, at Framingham State College. The talk, "Darwin and the Evolution of Reasons", was interesting, and meta-interesting; it not only was a good presentation of memetic evolution, it was a good demonstration of it as well, with successful elements of his earlier talks replicating themselves in this one. (Also, in a vivid display of horizontal meme transfer, I invite any who saw Dennett's talk to also watch Sue Blackmore's TED talk, to count the number of similar memes. For those who did not see Dennett, the Blackmore talk will give you the gist of it. No, they are not identical; variety exists among members of this species.)

After the talk (and the exodus of rude students who must have been there only for class credit), Dennett invited questions from the audience. Two (or maybe three; my notes are not clear) questions stood out for me, questions which explored Dennett's claim that, despite our robots-made-of-robots-made-of-robots bodies, and the unthinking replicant memes infecting our brains, we humans have free will--a free will of the sort worth having. The last questioner asked whether we were actually free moral agents, or whether we were the hosts to parasitic moral memes; Dennett's reply did not really satisfy me (nor my philosopher friend). Dennett made the analogy (a big part of his talk, too) of eukaryotic cells enjoying the benefits of the combined prokaryotic cells which compose them, and of humans enjoying the benefits of our symbiotic memes. All well and good, as far as that goes, but it seemed a strain to speak of memes as evolving separately, substrate-free, not caring about their human hosts other than as a means to reproduction, and then to turn around and claim that as a portion of our free will!

Perhaps I am misunderstanding him, but I have certainly read enough of his writing to doubt that, and I have read enough to know that Dennett misunderstands some aspects of some areas of my own expertise (which I would go into detail about, but it would rather get in the way of trying to remain an anonymous cuttlefish), so I have no illusion that he is infallible.

In another example of memetic transfer, I offer a replicated song. The structure (and tune, if you are inclined to sing it) are replicated from the original by Joni Mitchell; the first replication by Judy Collins shows that structure, descended with modifications in the chords, can successfully sell. Both versions are beautiful. Mine, less so.
Memes, it seems, are parasites
Inside our minds, so Dennett writes;
Poetic turns, and verbal flights
Evolving in our brains
But then he claims that we are free
To choose among the things we see
It doesn’t fit, it seems to me,
His explanation strains

I’ve looked at memes and at free will
From every way I can, but still
In spite of Dennett’s siren call
I don’t believe we’re free… at all

Memes are things that replicate
At really an astounding rate
From blind selection, they create
A culture that evolves
But now the concept gives me pause
I’ve got to stop and look for flaws
This explanation—might it cause
More problems than it solves?

I’ve looked at memes and at free will
From every way I can, but still
In spite of Dennett’s siren call
I don’t believe we’re free… at all

Love and hate and peace and war
Are memes that were selected for
Dreams and themes you can’t ignore—
Memetic, every one.
It seems the memes are in control
They take the place, they play the role
We used to say required a soul
Now souls are all undone

I’ve looked at memes and at free will
From every way I can, but still
In spite of Dennett’s siren call
I don’t believe we’re free… at all
