Perhaps you should try some spelling variations:
"philanthropists" » "philanthropic", "philanthropics", "philanthroposs"
"philanthropism" » "philanthropinism", "philanthropismus", "philanthropic"
"philanthrophist" » "philantropist", "philanthropic", "philanthropos"
"philanthropist" » "philanthropic", "philanthropos"
"philanthropy" » "philanthropic"

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 "philanthrophist") OR ("philanthropist" OR "philanthropy"))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(\"philanthropists\" or ((\"philanthropism\" OR \"philanthrophist\") or (\"philanthropist\" or \"philanthropy\")))".
• Removing quotes may allow a broader search: ( philanthropists or (( philanthropism OR philanthrophist ) or ( philanthropist or philanthropy ))).
• Adding a wildcard symbol may retrieve word variants: ("philanthropists" or (("philanthropism" OR "philanthrophist") or ("philanthropist" or "philanthropy")))*.
