Perhaps you should try some spelling variations:
"formal epistemology" » "moral epistemology", "social epistemology", "personal epistemology"
"legal epistemology" » "social epistemology", "personal epistemology"
"logic epistemology" » "genetic epistemology"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("legal epistemology") OR ("logic epistemology"))) OR ("formal epistemology")).
• Removing quotes may allow a broader search: (((( legal epistemology ) or ( logic epistemology ))) or ( formal epistemology )).
• Adding a wildcard symbol may retrieve word variants: (((("legal epistemology") or ("logic epistemology"))) or ("formal epistemology"))*.
