Perhaps you should try some spelling variations:
"praktische philosophical" » "praktische philosophie", "praktischen philosophie", "praktischer philosophie"
"practical philosophical" » "political philosophical", "critical philosophical", "poetical philosophical"
"practice philosophical" » "partie philosophical", "pragmatics philosophical", "practice philosophy"

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: (("praktische philosophical") OR ((("practice philosophical") OR ("practical philosophical"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"praktische philosophical\") or (((\"practice philosophical\") OR (\"practical philosophical\"))))*".
• Removing quotes may allow a broader search: (( praktische philosophical ) or ((( practice philosophical ) OR ( practical philosophical ))))*.
