What is the obverse of 'All S are P'?

Explanation:
Obversion changes the quality of a proposition and negates the predicate while keeping the subject the same. From “All S are P,” you switch the statement to a negative predicate, yielding “All S are not-P.” This preserves the universal scope and expresses the same idea as saying no S are P, just in the form where the predicate is the complement of P.
