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

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