## The Square of Opposition

The square of opposition is a diagram that helps to understand the logical relationships between the four basic propositions in a syllogism. The four propositions are:

All A are B

No A are B

Some A are B

None of A are B

The square of opposition is drawn as a square, with the four propositions represented by the four corners. The lines between the corners represent the logical relationships between the propositions.

The top line represents the relationship between “All A are B” and “None of A are B”. This line is called the “contrapositive”. The contrapositive states that if “None of A are B”, then “All A are not B”.

The left line represents the relationship between “No A are B” and “Some A are B”. This line is called the “inverse”. The inverse states that if “Some A are B”, then “No A are not B”.

The right line represents the relationship between “Some A are B” and “All A are B”. This line is called the “converse”. The converse states that if “All A are B”, then “Some A are B”.

The bottom line represents the relationship between “None of A are B” and “Some A are B”. This line is called the “complement”. The complement states that if “Some A are B”, then “None of A are not B”.
