Perhaps you should try some spelling variations:
"philanthropos" » "philanthropic", "philanthropy"
"philantropist" » "philanthropist", "philanthrophist", "philanthropies"
"philanthropism" » "philanthropist", "philanthropinism", "philanthropismus"
"philanthropists" » "philanthropic"

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: (("philanthropos" OR "philantropist") OR ("philanthropism" OR "philanthropists")).
• Removing quotes may allow a broader search: (( philanthropos or philantropist ) or ( philanthropism or philanthropists )).
• Adding a wildcard symbol may retrieve word variants: (("philanthropos" or "philantropist") or ("philanthropism" or "philanthropists"))*.
