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

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: ("philanthropos" OR ((("philanthropism" OR "philanthropismus") OR "philanthropist") OR "philanthropists")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(\"philanthropos\" or (((\"philanthropism\" OR \"philanthropismus\") or \"philanthropist\") or \"philanthropists\"))".
• Removing quotes may allow a broader search: ( philanthropos or ((( philanthropism OR philanthropismus ) or philanthropist ) or philanthropists )).
• Adding a wildcard symbol may retrieve word variants: ("philanthropos" or ((("philanthropism" OR "philanthropismus") or "philanthropist") or "philanthropists"))*.
