Well, i didn't say it's going to be easy...

To understant what I want to say requires lots of attention !

Let's say I want to build a thing in the real world, not just in my mind...so far so good, if let's say I want to build a system or a mechanism based on the principle that 1+1=9, now, can I realize this object, can I turn my dream into reality ? NO ! Reality works based on the principle that 1+1=2. So, if i want to make something real I am obligated to respect logic (correctness) 1+1=2. Why am i not allowed to build something real based on an erroneous principle ? What is this something that does not allow me to realize, to transform into something real my insane(crazy, non truth, non logical) dream (1+1=9) ? And why ?

I am asking basically here "what is a mistake, what is erroneous ?"

This is the importance of logic, of correctness, it alows us to turn something from inside our minds into something real, but only by respecting the laws of logic this is possible, otherwise we fail !

PS: Please excuse my english mistakes, I am from another country and is dificult for me to think into a diffrent language and translate into english exactly what I want to show you...is pretty hard even in my own language to make someone understand what I want to say because it's hard to speak of logic and the importance of it, etc, etc.
