For Searle the Is-Ought gap is the same as the fact/value gap 
& the descriptive/evaluative gap.

If this is right, Putnam misses the point.  Whether we NEED to or not, CAN 
we derive an "ought" from an "is"?  There might be "oughts" which cannot 
be derived & others which can.  Of the latter, CAN they only be derived from "is es".
