Perhaps you should try some spelling variations:
"philanthropist" » "philanthropos", "philanthropy"
"philanthropists" » "philanthroposs", "philanthropys", "philanthropos"
"philanthropys" » "philanthropy", "philanthropos", "philanthropus"
"philanthropism" » "philanthropinism", "philanthropismus", "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: ((("philanthropic" OR "philanthropist") OR ("philanthropists" OR "philanthropys")) OR "philanthropism").
• Removing quotes may allow a broader search: ((( philanthropic or philanthropist ) or ( philanthropists or philanthropys )) or philanthropism ).
• Adding a wildcard symbol may retrieve word variants: ((("philanthropic" or "philanthropist") or ("philanthropists" or "philanthropys")) or "philanthropism")*.
