## Syllogisms

The structure of the logical syllogism involves premise statements and a conclusion.  Generally, syllogisms are made up of three statements (two premises and a conclusion).  In those three statements, there are three concepts that are related (A, B, and C).  The Syllogism then becomes:

1. Premise: A is B
2. Premise: C is A
3. Conclusion: Therefore C is B

There is also a way to introduce a negative.  (Note how this changes the order of the C relationship to A and B.)

1. Premise: A is B
2. Premise: C is not B
3. Conclusion: Therefore C is not A.

The following videos give further explanations as well as examples.
