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