Dear colleagues
 
In a recent conversation as part of a Philosophy and Christian Thought class (third year B Th through Flinders University), Descartes' notion of people doing their own thinking came up. 
 
I said I recall a theologian had pictures of his favourite theologians on the wall alongside his staircase.  The top portrait was a mirror.
 
Does anyone remember who that theologian might have been?  I thought it might have been Karl Barth, but it might have been one of the four RS-I theologians, or someone else.
 
Can anyone help?
 
Best wishes
