Perhaps you should try some spelling variations:
"philanthropism" » "philanthropinism", "philanthrophist", "philanthropie"
"philanthropismus" » "philanthropinismus", "philanthrophistus", "philanthropieus", "philanthropicus", "philanthropisches", "philanthropies"
"philanthropists" » "philanthropys"
"philanthropist" » "philanthropy"
"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 ("philanthropist" OR "philanthropos")) OR "philanthropic")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(\"philanthropists\" or (((\"philanthropism\" or \"philanthropismus\") or (\"philanthropist\" OR \"philanthropos\")) or \"philanthropic\"))".
• Removing quotes may allow a broader search: ( philanthropists or ((( philanthropism or philanthropismus ) or ( philanthropist OR philanthropos )) or philanthropic )).
• Adding a wildcard symbol may retrieve word variants: ("philanthropists" or ((("philanthropism" or "philanthropismus") or ("philanthropist" OR "philanthropos")) or "philanthropic"))*.
