Philosophy is subordinate to love in what goes to a Scotsman’s head (6)
I believe the answer is:
taoism
'philosophy' is the definition.
(I know that Taoism is a type of philosophical doctrine)
'is subordinate to love in what goes to a scotsman's head' is the wordplay.
I cannot really see how this works, but
'is' is present in the answer.
'love' could be 'o' (love means zero in tennis) and 'o' is located in the answer.
'a' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for taoism that I've seen before include "Confused Maoist in Chinese religious system" , "philosophy in China" , "Religious movement" , "Maoist (anag) -- Chinese religion" , "Chinese philosophical system" .)
