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