Terminology: ontic/ontological, epistemic/epistemological?
Reply to Nathan Holmes
There are distinctions worth recognizing between 'ontic' and 'ontological'. The numbers are ontic entities. The theories of the nature of numbers are ontological. I would be reluctant to use the word 'ontological' in situations where explicit reference to the study of mind-independent reality is not called for.   
There are distinctions worth recognizing between 'epistemic' and 'epistemological'.  My knowledge of the numbers is  epistemic. Claims about my knowledge are epistemological.  I would be reluctant to use the word 'epistemological' in situations where explicit reference to the study of certain mind-dependent reality is not called for.   
There are distinctions worth recognizing between 'mental' and 'psychological'. The thoughts I am now having are all mental, not psychological.I would be reluctant to use the word 'psychological' in situations where explicit reference to the study of mental reality is not called for.
