    Contraposition(I am so lost:-)

    The process for Contraposition is to :
    1. Obvert the statement
    2. Convert the statement
    3. Obvert the statement again.

    It can ONLY be used with A and O statements.

    However, according to the book, "Conversion, in other words, does not work with A and O statements"(Pg. 84 1st paragraph).

    Question: How can you Contrapose a statement if you can't convert it?

    Conversion

    Although conversion does not work on A statements, the procedure involved in contraposition has you obvert the A statement before you convert it. Once you have obverted it, you no longer have an A statement, but an E statement. It is only then that you are asked to convert it.

    In short, contraposition does not ask you to convert an A statement, but an E statement.

    Does that make sense?
