Dictonary says wizards can cast spells. I say I'm a wizard. That means I can cast spells. Air tight logic, right?

In order to be a Wizard ,Wiggot, Black Magician, Succumbus Sanitizer or anything to do with the side of the male occult you must be mentaphysically knowlegable.There is no information concerning this and you cannot be taught .You either are or you aren't but time will tell and that is the objective -Stay Alive

No. You say you are a wizard. Therefore you imply you can cast spells. This does not mean you can.

Saying "I'm a wizard" doesn't make you a wizard because if you're not really a wizard you can't successfully cast a spell. Ergo, there may actually be no "wizards" because it's doubtful that anyone can actually cast a spell.

Before you could do this, you need to know the spells. Wizard is an old word that means, among other things, Wise.

No, that's not airtight logic unless your actions stand by the definition you are going by.

Saying it's about "equality" and that that's what it says in the dictionary is worthless as long as the actions in real life show otherwise.

Sounds like the theory of Evolution, They say something evolved from nothing, so it means it happens even without evidence or logic to prove it.

By no logic can I be convinced that you are a wizard.
