Perhaps you should try some spelling variations:
"philanthropists" » "philanthropos", "philanthroposs", "philanthropys"
"philanthropist" » "philanthropos", "philanthropy"
"philanthropism" » "philanthropinism", "philanthrophist", "philanthropos"
"philanthropismus" » "philanthropinismus", "philanthrophistus", "philanthroposus", "philanthropicus", "philanthropisches", "philanthropies"
"philanthropinismus" » "philanthropinism", "philanthropicus"

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