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