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: ((("philanthropists" OR "philanthropic") OR "philanthropos") OR ("philanthropism" OR "philanthropist")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((\"philanthropists\" OR \"philanthropic\") or \"philanthropos\") or (\"philanthropism\" or \"philanthropist\"))".
• Removing quotes may allow a broader search: ((( philanthropists OR philanthropic ) or philanthropos ) or ( philanthropism or philanthropist )).
• Adding a wildcard symbol may retrieve word variants: ((("philanthropists" OR "philanthropic") or "philanthropos") or ("philanthropism" or "philanthropist"))*.
