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

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