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