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

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