Converse (logic)

Converse (logic)

In logic, the converse of a categorical or implicational statement is the result of reversing its two parts. For the implication PQ, the converse is QP. For the categorical proposition All S is P, the converse is All P is S. In neither case does the converse necessarily follow from the original statement. The categorical converse of a statement is contrasted with the contrapositive and the obverse.

Famous quotes containing the word converse:

    “You are old, Father William,” the young man cried,
    “And life must be hastening away;
    You are cheerful, and love to converse upon death:
    Now tell me the reason, I pray.”

    “I am cheerful, young man,” Father William replied;
    “Let the cause thy attention engage;
    In the days of my youth I remembered my God,
    And He hath not forgotten my age.”
    Robert Southey (1774–1843)
