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

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 philanthropies) OR (philanthropist OR philanthropos) ) OR ( philanthropism OR philanthrophist ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( (philanthropists or philanthropies) or (philanthropist OR philanthropos) ) or ( philanthropism or philanthrophist ))*".
