20 philosophy » 10 philosophy, 23 philosophy, 0 philosophy
24 philosophy » 14 philosophy, 23 philosophy, 1.4 philosophy
13 philosophy » 1 philosophy, 3 philosophy, 10 philosophy
4 philosophy » 1 philosophy, 5 philosophy, 3 philosophy
6 philosophy » 1 philosophy, 6 philosophie
2 philosophy » 1 philosophy

Try widening your search to All Fields.

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: %22science %((((((20 philosophy) OR (24 philosophy))) OR (((4 philosophy) OR (6 philosophy))))) OR (((13 philosophy) OR (2 philosophy))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22science %((((((20 philosophy) OR (24 philosophy))) or (((4 philosophy) or (6 philosophy))))) or (((13 philosophy) or (2 philosophy))))%22".
• Adding a wildcard symbol may retrieve word variants: %22science %((((((20 philosophy) OR (24 philosophy))) or (((4 philosophy) or (6 philosophy))))) or (((13 philosophy) or (2 philosophy))))%22*.
