Perhaps you should try some spelling variations:
"philanthropus" » "philanthropos", "philanthropist", "philanthropies"
"philanthropie" » "philanthropist", "philanthropy", "philanthropos"
"philanthropism" » "philanthropist", "philanthropinism", "philanthropismus"

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