Perhaps you should try some spelling variations:
"philanthropos" » "philanthropy"
"philanthropism" » "philanthropinism", "philanthropismus", "philanthrophist"
"philanthropists" » "philanthropys"
"philanthropist" » "philanthropy"

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: ((("philanthropos" OR "philanthropists") OR "philanthropic") OR ("philanthropism" OR "philanthropist")).
• Removing quotes may allow a broader search: ((( philanthropos or philanthropists ) or philanthropic ) or ( philanthropism or philanthropist )).
• Adding a wildcard symbol may retrieve word variants: ((("philanthropos" or "philanthropists") or "philanthropic") or ("philanthropism" or "philanthropist"))*.
