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