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