Perhaps you should try some spelling variations:
"der methodischen positivismus und" » "der zwischen positivismus und", "des methodischen positivismus und", "zum methodischen positivismus und"
"zur methodischen positivismus und" » "zur zwischen positivismus und", "zum methodischen positivismus und", "des methodischen positivismus und"

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: "((\"der methodischen positivismus und\") OR (\"zur methodischen positivismus und\"))*".
• Removing quotes may allow a broader search: (( der methodischen positivismus und ) OR ( zur methodischen positivismus und ))*.
