Contradictory item is the only one that surely exists

[eighth man]

A contradictory item (or concept, or object ) is the only one that exists in the universe because it can deceive all logic and reasoning and as such does not depend on any reasoning to exist.

If contradictory item A is such that A=3 and also A=17, and A exists and A also does not exist, then A is the most sure thing to exist because it can always escape any logic regarding its existence. Its existence does not depend on any logic any rule or any constraint, not even the one of being true or false. It is hard to reason with this item because all reasoning breaks down, but this proves that it is the most sure thing possible, since nothing can contradict it, as it actually accepts and thrives on contradiction.

You imply here that "Rational entities depend on reasoning in order to exist," and you assert that "Only contradictory (irrational) entities exist." Taken together, these statements imply that no rational things exist and (perhaps) that there is no rational thought. Obviously rational thought exists, however, and science wouldn't be possible if nature didn't behave in a rational way.

Besides making apparently false claims, you make a rather counterintuitive claim about how it is that things exist. It's not at all clear why it would (or could) be that anything depends on reasoning in order to exist, in the sense you seem to be implying here. Perhaps you could maintain that sort of position with some kind of convoluted idealism. However, strong claims require strong evidence, and there is none here (and I really don't see how there could be any, even in principle, given what we know about nature). Ultimately, this thread doesn't meet the philosophy forum guidelines on a number of counts.
