Perhaps you should try some spelling variations:
"legal epistemology" » "social epistemology", "personal epistemology"
"moral epistemology" » "formal 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 ((("moral epistemology") OR ("logic epistemology")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"legal epistemology\") or (((\"moral epistemology\") OR (\"logic epistemology\"))))".
• Removing quotes may allow a broader search: (( legal epistemology ) or ((( moral epistemology ) OR ( logic epistemology )))).
• Adding a wildcard symbol may retrieve word variants: (("legal epistemology") or ((("moral epistemology") OR ("logic epistemology"))))*.
