Perhaps you should try some spelling variations:
"philanthropists" » "philanthropic", "philanthropics", "philanthropys"
"philanthropism" » "philanthropinism", "philanthropismus", "philanthrophist"
"philanthropies" » "philanthropie", "philanthropic", "philanthropy"
"philanthropist" » "philanthropic", "philanthropy"
"philanthropos" » "philanthropic", "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 "philanthropies") OR ("philanthropist" OR "philanthropos")))*.
• Removing quotes may allow a broader search: ( philanthropists or (( philanthropism or philanthropies ) or ( philanthropist or philanthropos )))*.
