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

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