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

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