Where is your question?? What does this gibberish have to do with syllogistic logic??

Venn diagrams are used to interpret and decide which of Aristotle's syllogisms are vaid or not. There are no 'minimum/maximum' relations here.

x exists, means, there is some confirmable property that x has. (E!x =df EF(Fx)). If it is true that x thinks then x exists. We cannot deny our existence, because the process of denying requires existence. If there is anything that x does or says then that x must exist.

Division is a mathematical operation between numbers or functions of numbers. Separating objects into parts is not division. That we can simulate the operation of division applied to pies etc, has restrictive meaning. What would (pie)/pi mean? I don't think there is a knife sharp enough...

If classical logic is inconsistent then so is classical mathematics. A. x=y -> (Fx <-> Fy). This is an axiom of first order logic and it is a theorem of second order logic. (Leibnitz's Law) A is a theorem of Principia Mathematica, *13.15. 1. x=y -> ([](x=x) <-> [](x=y)). therefore...

x is unique means, there is one and only one thing that x is. 'The' in the particular, in the singular, is the meaning of 'unique'. The definite article 'the' refers to that one and only x. The x such that Fx, is that (unique) x which satisfies Fx. That there is only one x which...

Reality is all that is the case. What is not the case is not part of reality. Even dreams are partof reality, even if the 'objects' in that dream are not.

"A point has zero volume, zero area, zero length, and cardinality 1." All geometric concepts have no physical qualities. Points do not have physical qualities at all. "The phrase "X doesn't have volume" means that the concept of volume is inapplicable to X." Wrong again. X has zero...

What, you are absolutely certain that you are uncertain?? Surely this is self contradictory!

I don't care at all about your re-defining of words that are clear and distinct. You sound like a theist who wants to define classical words as they please?? Why do you think I should be concerned about your special definition of object etc. If you want to talk about point-objects, then...
