Wise remark introducing philosopher's works (7)
I believe the answer is:
sawmill
'works' is the definition.
(sawmill is a kind of works)
'wise remark introducing philosopher's' is the wordplay.
'wise remark' becomes 'saw' (saw can mean an adage or proverb).
'introducing' means to remove the last letter.
'philosopher's' becomes 'mill's' (John Stuart Mill).
'mills' with its final letter taken off is 'mill'.
'saw'+'mill'='SAWMILL'
(Other definitions for sawmill that I've seen before include "country establishment" , "Log cutting plant" , "Timber cutting factory" , "should make a good deal" , "Place where timber is cut into planks" .)
