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