Perhaps you should try some spelling variations:
"philanthropism" » "philanthropist", "philanthropinism", "philanthropismus"
"philanthropisches" » "philanthropische", "philanthropischen", "philanthropists"
"philanthropos" » "philanthropy", "philanthropists"

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