African on CBS rubbished English philosopher (7,5)
I believe the answer is:
francis bacon
'english philosopher' is the definition.
'Francis Bacon' can be an answer for 'philosopher' (Francis Bacon is an example). I am not certain of the 'english' bit.
'african on cbs rubbished' is the wordplay.
'rubbished' indicates an anagram.
'african'+'on'+'cbs'='africanoncbs'
'africanoncbs' anagrammed gives 'FRANCIS BACON'.
Can you help me to learn more?
(Other definitions for francis bacon that I've seen before include "English philosopher, d. 1626 - Dublin-born painter, d. 1992" , "Statesman and philosopher, 1561-1626 - painter, 1909-92" , "Renaissance man" .)
