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