Mike Flynn got bored, so he decided to increase traffic to his livejournal by taking the name of Darwin in vain.
Looks like it worked. =) He quotes David Stove, who was an Australian philosopher of the grumpy old man school (I mean that as a compliment). Stove was a ruthless exposer of poppycock in philosophy, of which there is always plenty to be exposed. There is a certain tendency to create 'Just-So' stories about the evolution of a given trait that incensed Stove to humorous result.
In a six-degrees-of-separation kind of thing, Jim Franklin is the literary executor of David Stove's works, so I suppose that makes me only 3 degrees from Stove myself. Well, three-and-a-half.
