Ergo: --> {} intersection B = {} for all sets B
- For any set A, the empty set is a subset of A:∀A: {} ⊆ A
- For any set A, the union of A with the empty set is A:∀A: A ∪ {} = A
- For any set A, the intersection of A with the empty set is the empty set:∀A: A ∩ {} = {}
You should simply rely on the definitions, like a robot. That is really the safest for you, and will put you back in line with the rest of the educated world.
There is no contradiction.
Do you really believe that millions of mathematicians, logicians, including the greatest minds of the last two centuries, educators, students, etc. could have missed such a huge and obvious contradiction at the root of the fundaments of their discipline?
it is a fact known since the beginning of logic, that claims about the members of an empty set always obtain
well. i gave you a chance of thinking, and revise your nonsensical position. Now I am entitled to be ruthless.No, of course not. YOU are missing the contradiction. Not them, not me. YOU.

everyone agrees with me. this is basic stuff, as it is expected to be understood by people as young as 10. so, congratulations, I guess
You are in a state of delusion and denial that I never experienced. compared to you, a flat earther is a deep and critical thinker. Same with YECs.
do you have an explanation why all web sites, all articles, all books, all introductory courses, all you can find, including the courses for little children i showed you , all of them, without any exception, agree that the empty set is a subset of any set? Don’t you see that you are just hurting yourself, and embarrassing yourself by insisting on something that is completely untenable?

So, why is it that "{} intersected with any set B = {}" is considered a true statement? I am arguing that it shouldn't be. But, ignoring that, it's because intersected does not mean intersected in this context. {} is an exclusion. "Intersected" is an inclusion. {} contradicts with "intersected" So, it should be evaluated/understood in the reverse. However, "any set B" is inclusion. The "=" sign is inclusion. So the conclusion can be easily understood, naturally, but the operation must be evaluated IN CONTRADICTION.
This is simple math. -1 + 1 = 0. The negative sign indicates that -1 is contradicted with 1. Because of this, the addition is not evaluated as inclusion, it is evaluated IN CONTRADICTION of what the plus sign naturally means. (-1) + (-1) = -2. Here, there is no contradiction. The operator is evaluated naturally. (-1) - (-1) = 0. This is the same. There is no contradiction between -1 and -1. So the subraction is evaluated naturally. (-1) - ( 1) = -2. Here there IS a contradiction between -1 and 1 so the subraction is not evaluated as subtraction, instead it is evaluated as the opposite. All of this renders true conclusions BECAUSE the contradiction is accepted but NOT ignored.
Not beautiful. obvious. Since the empty set contain no element.
Yes, all correct. The latter destroys your point.
By people that have no clue About the subject. True.This is not easily understood.
You are just out of your mind, if any. You are so desperate that you are making up things and generate nonsense at a rate that would make Ken Hovind look like Einstein. Or Trump look like the wisest man on earth.If it is read naturally, this means {} has elements in common with { 1 }. But that is NOT what it means. It acutally means the opposite. The ⊂ symbol is meaning inclusion. The ∅ symbol means exclusion. This is like -1 + 1. The negative 1 contradicts with positive 1, in the same way that the ∅ contradicts with the ⊂. So, in order to evaluate/understand this statement, the operator CANNOT be applied naturally. It MUST be applied in reverse, in opposition, in contradiction! This statement does not mean that ∅ is a subset in any natural way. It means the opposite, it is not a subset in any natural way. ∅ does NOT share any elements with { 1 }, there is NO correspondence.
For any set A:Examples:

This is easily understood. {} excludes, the operator excludes, there is no contradiction, the statement means what it says, naturally: " The empty set contains no elements of the empty set." Beautiful.
View attachment 76321
This also easily makes sense. There is no contradiction between the a set of negation and an operator which negates.

Because of this it is incorrect to say "an empty set is a subset of any set". "Empty set" is an inclusive object. "IS" is an inclusive operator. "Subset" is an inclusive object. But {} is exclusion. This is not communicated in the english statement above! In order for the statement to understood in english, naturally, the exclusion MUST be included.
If you don't know any Jews, then "All the Jews I know are Atheists" is false! "All the Jews I know are Atheists or not" is True!
Clearly the statement "an empty set is a subset of any set" is not true because I have given many examples where it is not true.
{ 1,2,3 } =/= { 1,2,3{} }. Done. Proven.

The part in red is a contradiction. The part in blue is not.
{} is a subset of any set? No.
The part in red is a contradiction. "Is" needs to be evaluated/understood in reverse.
{} is not a subset of any set? Yes.
The part in blue is not a contradiction. "Is not" can be read/understood naturally.
{} is an unsubset of any set? Yes.
{} is not an unsubset of any set? No.
No. You do not understand. And you have probably misunderstood for decades. If you were taught this, you were taught wrong. if you have been teaching this, you have been teaching wrong. Hopefully, you didn't berate or ridicule any students who naturally objected to this idea on principle if you demonstrated it to them. Young people with strong morals and principles should be encouraged. Not discouraged in spite of any atheist-zealotry which cannot see any good in a principled religious person.
"claims about the members of an empty set always obtain"
No.
"Claims about the members" is inclusion. The "empty set" is exclusion. "obtain" is inclusion. The exclusion contradicts with the inclusion. The statement needs to be evaluated/understood in reverse.
"Claims about the members of an empty set NEVER obtain." True!
"All the Jews you know are Atheists" is false if you don't know any Jews.
Does Drexel University say that empty sets are not subsets of all sets? Where? and what on earth is Drexel University?Asked and answered in the posts provided. You need to read the entire thing. Since I am going up against everyone and everything you believe in, it takes a lot of words to prove all of those people and all of those things false.
Here is the the answer to your question. Summarized. Again, everything I wrote above needs to be read in order to understand {}.
That pretty much explains it. As I said. We agree on the facts. You simply don't understand what they mean. Drexel university agrees with me, and they don't agree with you.
all of them, without any exception, agree that the empty set is a subset of any set?
However, if the perscription is to rely, like a robot, on what is defined, then {} is NOT a subset of any set. See below from drexel university:
Every nonempty set has at least two subsets, ∅ and itself. The empty set has only one, itself.The empty set is a subset of any other set, but not necessarily an element of it.
That ^^ is the complete defintion. Anyone who omits part of it is liable to be very confused and develop false conclusions. This is contrary to logic. Logic develops true conclusions.
In plain english, ∅ is a subset unlike any other subset that exists. That is what it means when the definition says, "BUT not necessarily an element of it." "BUT" means it is NOT a subset. A subset MUST include a shared element. This is defining something which is NOT a subset. It is something else.
This definition IS contradictory and true BECAUSE ∅ contradicts! And that is what makes it true! It is negation. It is true falsehood. Truly false. That's what ∅ MEANS. It can be described as a subset, if and only if it is understood that is not a subset. This is because ∅ is a set unlike any other set that exists. This makes sense, because the set which is not like any other set can be described as a subset which also is not like any other subset. The empty set can be described as a set, if and only if it is understood that it is not a set. If these understandings are lost or ignored, or not taught, then the words "set" and "subset" no longer apply because they are always describing inclusion and when these words are applied in negation, with ∅, they are describing the opposite.
That does not make your case. Where does it say that?Not true. The definition from Drexel University has the complete defintion.
Every nonempty set has at least two subsets, ∅ and itselfNot true. The definition from Drexel University has the complete defintion.
Don’t you realise how embarassing that post of yours is? You just proved what I maintain. Even your beloved University maintains that every set has the empty set as subset. LOL.However, if the perscription is to rely, like a robot, on what is defined, then {} is NOT a subset of any set. See below from drexel university:

So, when are you publishing your results? According to your delusion you have just destroyed centuries of logic, and I am sure that will make you very famous.
read my lips. The empty set is a subset of every set. So, please post a complain on wikipedia, and all those millions of web sites claiming the contrary, and you are in business. Until that, you will just count as yet another person su

We already know the empty set is different from any other set. That is trivial, since all the other sets contain elements. And what does it mean it is the opposite of a subset? What on earth is the opposite of a subset? That is unintelligible nonsense, and where does it say that in the post you thought was a rebuttal of my position?It is a subset, But not like any other subset that exists. That's what it says in the PDF from Drexel. You don't seem to understand what makes this so-called subset different. It's the opposite of a subset.
very well, then, let’s start with the first. This is going to be fun.I've already beaten you 3 times. Unless you can show any fault in my reasoning in any of these three proofs I have provided, then all of this bluster is just the protesting over being beaten.
1) { 1,2,3 } =/= { 1,2,3,{} } - Game over
2) {} is disjointed with all sets including itself. By definition. - Game over
3) {} is negation, which requires evaluating any inclusive operator following in contradiction. {} is a subset of all non-empty sets MEANS {} is not a subset of any of them. This is because {} contradicts with "is a subset" in the same way that -1 contradicts with 1 in -1 + 1 = 0. This contradiction requires that the operator be evaluated/understood in contradiction. - Game over
#3 resolves the contradiction between the statement "{} is disjointed from all including itself", while simultaneously "{} is a subset of all including itself". {} contradicts with "is a subset". So the operator needs to be understood in contradiction. However, " {} is disjointed ... " is not a contradiction, so it can be understood naturally. "{} is a subset of any set" actually means the opposite "{} is disjointed from all including itself."
Prove me wrong. Good luck hot-shot.
