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