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

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 ("philanthropism" OR "philanthrophistus")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"philanthropists\" or (\"philanthropist\" OR \"philanthropic\")) or (\"philanthropism\" or \"philanthrophistus\"))".
• Removing quotes may allow a broader search: (( philanthropists or ( philanthropist OR philanthropic )) or ( philanthropism or philanthrophistus )).
• Adding a wildcard symbol may retrieve word variants: (("philanthropists" or ("philanthropist" OR "philanthropic")) or ("philanthropism" or "philanthrophistus"))*.
