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