Perhaps you should try some spelling variations:
"philanthropists" » "philanthropos", "philanthroposs", "philanthropys"
"philanthropist" » "philanthropos", "philanthropy"
"philanthropicus" » "philanthropiques", "philanthropismus", "philanthropies"

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