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

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