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

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