Perhaps you should try some spelling variations:
"philanthropism" » "philanthropist", "philanthropinism", "philanthrophist"
"philanthropismus" » "philanthropistus", "philanthropinismus", "philanthrophistus", "philanthropicus", "philanthropisches", "philanthropist"
"philanthropists" » "philanthropic", "philanthropos"

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