The quote was in an article titled Evolutionary Psychology and went like this (emphases in original):
Cognitive causes are ontologically distinct from evolutionary causes. They are made out of a different kind of stuff. Cognitive causes are made of neurons. Evolutionary causes are made of ancestors.
The most obvious kind of cognitive cause is deliberate, like an intention to go to the supermarket, or a plan for toasting toast. But an emotion also exists physically in the brain, as a train of neural impulses or a cloud of spreading hormones. Likewise an instinct, or a flash of visualization, or a fleetingly suppressed thought; if you could scan the brain in three dimensions and you understood the code, you would be able to see them...
Evolutionary selection pressures are ontologically distinct from the biological artifacts they create. The evolutionary cause of a bird’s wings is millions of ancestor-birds who reproduced more often than other ancestor-birds, with statistical regularity owing to their possession of incrementally improved wings compared to their competitors. We compress this gargantuan historical-statistical macrofact by saying “evolution did it”.
...When we’re told that “The evolutionary purpose of anger is to increase inclusive genetic fitness,” there’s a tendency to slide to “The purpose of anger is reproduction” to “The cognitive purpose of anger is reproduction.” No! The statistical regularity of ancestral history isn’t in the brain, even subconsciously, any more than the designer’s intentions of toast are in a toaster!
