But that is an act you can not do by the rules of logic.

You CAN create a new system with your new definition, which you are 
welcome to try to spend your next 20 years or so doing (if you still 
have them), but you can not just change the definitions in the existing 
systems, as that just doens't work, and your attempting to do so just 
shows your ignorance of how Formal Logic works.
