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

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