Able to be looked upon as intelligent perception (7)
I believe the answer is:
insight
'able to be looked' is the definition.
I can't tell whether this defines the answer.
'as intelligent perception' is the wordplay.
'as' becomes 'in' (I've seen this in other clues).
'intelligent perception' becomes 'sight' (sight is a kind of perception. I am not sure about the 'intelligent' bit.).
'in'+'sight'='INSIGHT'
'upon' is the link.
Can you help me to learn more?
(Other definitions for insight that I've seen before include "Enlightenment" , "Deep understanding" , "Furniture from Princes Street for" , "Intuitive understanding" , "comprehension" .)
