The Teiresias Effect, a.k.a., Having It Both Ways.
More fun for me this early in the AM is another transformation:
The juvenile sea squirt wanders through the sea searching for a suitable
rock or hunk of coral to cling to and make its home for life. For this
task it has a rudimentary nervous system. When it finds it's spot and
takes root, it doesn't need its brain any more so it eats it. It's
rather like getting tenure.
-Daniel C. Dennett (from *Consciousness Explained*, 1991)
I don't think the date is right since I remember seeing this in the
1970s. I wasn't *that* prescient.
