Perhaps you should try some spelling variations:
philosophy xxi » philosophy a, philosophy and, philosophy in
philosophy ii » philosophy in, philosophy a, philosophy and
philosophy el » philosophy a, philosophy in, philosophy and
xxi lenguaje » del lenguaje, y lenguaje, de lenguaje
ii lenguaje » y lenguaje, de lenguaje, en lenguaje
el lenguaje » del 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 el lenguaje ))) OR ( philosophy xxi lenguaje ))~".
• Adding a wildcard symbol may retrieve word variants: (((( philosophy ii lenguaje ) OR ( philosophy el lenguaje ))) OR ( philosophy xxi lenguaje ))*.
