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