Perhaps you should try some spelling variations:
"praktische philosophical" » "praktische philosophie", "praktischen philosophie", "praktischer philosophie"
"practice philosophical" » "practical philosophical", "pragmatics philosophical", "practice philosophy"
"partie philosophical" » "martin philosophical", "martins philosophical", "partly philosophicall"

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