The 3 Principles of Consistency

The Principle of non-contradiction

     you cannot be somwhere where you are not

     eg: This dot is here                                    It isn't here

The Principle of the excluded middle

     you cannot be half here                           and half here

     there is no middle ground between somewhere you are and somewhere you aren't.

The Principle of Identity

     you are what you are.

     eg: this dot () is a dot.

           it isn't a bus.
