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

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