20 philosophy » 23 philosophy, 24 philosophy, 0 philosophy
14 philosophy » 4 philosophy, 6 philosophy, 5 philosophy
13 philosophy » 3 philosophy, 603 philosophy, 6 philosophy
10 philosophy » 603 philosophy, 6 philosophy, 5 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 (14 philosophy))) OR (((((13 philosophy) OR (10 philosophy))) OR (((2 philosophy) OR (1 philosophy))))))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22science %((((20 philosophy) or (14 philosophy))) or (((((13 philosophy) or (10 philosophy))) or (((2 philosophy) OR (1 philosophy))))))%22".
• Adding a wildcard symbol may retrieve word variants: %22science %((((20 philosophy) or (14 philosophy))) or (((((13 philosophy) or (10 philosophy))) or (((2 philosophy) OR (1 philosophy))))))%22*.
