Unite disparate elements of argument framed by limits of sociology and nature (10)

'unite disparate elements' is the definition.

'argument framed by limits of sociology and nature' is the wordplay.
I cannot really see how this works, but
'argument' could be 'thesis' (I've seen this before) and 'thesis' is present in the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is found in the answer.
The remaining letters 'sye' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).

'of' is the link.
