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