Perhaps you should try some spelling variations:
philosophy xxi » philosophy a, philosophy and, philosophy in
philosophy ii » philosophy in, philosophy a, philosophy and
philosophy un » philosophy in, philosophy and, philosophy a
xxi lenguaje » del lenguaje, el lenguaje, y lenguaje
ii lenguaje » el lenguaje, y lenguaje, de lenguaje
un lenguaje » en lenguaje, en lenguajes, el lenguaje

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( philosophy ii lenguaje ) OR ( philosophy xxi lenguaje ))) OR ( philosophy un lenguaje ))~".
• Adding a wildcard symbol may retrieve word variants: (((( philosophy ii lenguaje ) OR ( philosophy xxi lenguaje ))) OR ( philosophy un lenguaje ))*.
