Perhaps you should try some spelling variations:
"philanthropist" » "philanthropos", "philanthropy"
"philanthropists" » "philanthroposs", "philanthropys", "philanthropos"
"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: (("philanthropist" OR "philanthropic") OR ("philanthropism" OR "philanthropists")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"philanthropist\" OR \"philanthropic\") or (\"philanthropism\" or \"philanthropists\"))".
• Removing quotes may allow a broader search: (( philanthropist OR philanthropic ) or ( philanthropism or philanthropists )).
• Adding a wildcard symbol may retrieve word variants: (("philanthropist" OR "philanthropic") or ("philanthropism" or "philanthropists"))*.
