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

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