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