Perhaps you should try some spelling variations:
"critical rationalism" » "critica rationalism", "criticas rationalism", "critico rationalism", "critical nationalism", "critical racionalismo", "critical regionalism"
"critical regionalismo" » "critica regionalismo", "criticas regionalismo", "critico regionalismo", "critical racionalismo", "critical nacionalismo", "critical regionales"
"critical rationality" » "critica rationality", "criticas rationality", "critico rationality"

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: "((((\"critical rationalism\") OR (\"critical regionalismo\"))) OR (\"critical rationality\"))~".
• Removing quotes may allow a broader search: (((( critical rationalism ) OR ( critical regionalismo ))) OR ( critical rationality ))~.
• Adding a wildcard symbol may retrieve word variants: (((("critical rationalism") OR ("critical regionalismo"))) OR ("critical rationality"))*.
