Induced to admit philosopher in courses (7)
I believe the answer is:
layered
'in courses' is the definition.
(in multiple courses or layers)
'induced to admit philosopher' is the wordplay.
'induced to' becomes 'led' (I've seen this before).
'admit' indicates putting letters inside.
'philosopher' becomes 'ayer' (AJ Ayer).
'led' placed around 'ayer' is 'LAYERED'.
(Other definitions for layered that I've seen before include "Like a particular hairstyle" , "Tiered" , "in tiers" , "Type of cake perhaps" , "Stratified" .)
