Should add Hume's guillotine is the obverse of this I think - that "can doesn't imply ought," what the later philosopher Moore similarly dismissed as being the "naturalistic fallacy" (i.e. that appeal to how people seemed to behave in a state of nature couldn't be used as a guide to how they ought to behave.)

(Also note there's no contradiction. "Can doesn't imply ought" is a different statement from "Ought implies can" - both can be true. It's all about the asymmetric nature of if-then statements.)
