Renaissance thinker one associated with Calvin (6)
I believe the answer is:
hobbes
'calvin' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see a link between them that I don't see?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for hobbes that I've seen before include "Thomas --, English philosopher (Leviathan)" , "17th century English philosopher" , "Thomas --, English political philosopher" .)
