My mind has a tendency to churn up all sorts of interesting things.
A few of my favourite ones are:
'mind and matter' - 'What makes mind make matter move'
'What makes matter make mind move'
'Name and Form' or more interestingly 'Name and Presumed form'.
'Science and Religion' or again more interestingly lets say, 'Name and object form'
and lets say 'Name and Subjective form'.
