Trembling, gutted after comic genius dismisses second philosopher (12)
I believe the answer is:
wittgenstein
'philosopher' is the definition.
(I know that Wittgenstein is a philosopher)
'trembling gutted after comic genius dismisses second' is the wordplay.
I cannot really see how this works, but
'comic' could be 'wit' (a witty person) and 'wit' is present in the answer.
'second' could be 's' (common abbreviation) and 's' is found within 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 wittgenstein that I've seen before include "British philosopher" , "Ludwig --, Austrian-born philosopher" .)
