If you mean by Stevensism that guy Steven Dawkings, he is dumbest of the lot. He cannot get anything right. All he gives is wild speculations and non-sensical "proofs". However, he is completely in the Darwinian tradition of charlatanism.
Gee, does that remind you of anyone?
Like someone who claimed that the planets have "wildly" elliptical orbits, and then tried to claim that RA's table of planetary eccentricities as "proof"?
Try looking in the mirror.
And when you're done, you could start apologizing to all the people you insulted on the thread whose only crime was trying to point out your error.
Not really; what I had in mind was the George Stevens' version of evolutionism...
