Perhaps you should try some spelling variations:
"philanthropos" » "philanthropy", "philanthropists"
"philanthropism" » "philanthropinism", "philanthropismus", "philanthropists"
"philanthropist" » "philanthropists", "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: (("philanthropos" OR "philanthropic") OR ("philanthropism" OR "philanthropist")).
• Removing quotes may allow a broader search: (( philanthropos or philanthropic ) or ( philanthropism or philanthropist )).
• Adding a wildcard symbol may retrieve word variants: (("philanthropos" or "philanthropic") or ("philanthropism" or "philanthropist"))*.
