He’d foretold a dim, woolly, position avoiding extremes (6,2,3,4)
I believe the answer is:
middle of the road
'avoiding extremes' is the definition.
(I've seen this before)
'he'd foretold a dim woolly position' is the wordplay.
'he'd foretold a dim' anagrams to 'MIDDLE-OF-THE-ROAD'.
Though, I'm not clear how this is indicated.
Can you help me to learn more?
(Other definitions for middle of the road that I've seen before include "cars shouldn't cross it" , "having a wide general appeal" , "Crown" , "place for one just passing" , "No extreme" .)
