Here's a thought. Draw the X axis. The segment between 0 and 1 is a physical extension in space. This segment contains an infinity of dimensionless po...

Thanks. The first thread in the Logic and Philosophy of Mathematics forum (this forum) explains how to use the math tag and how to create symbols.

"This is the answer to the question"
May 21, 2020 at 20:57
Is it the same as the answer to this question?

Simone Weil writes about this. The Jews did not have a concept of rights in the way we do. Their concept was the justice of God. Weil points out that ...

There are two spacetimes, quantum spacetime and physical spacetime. Quantum spacetime is an n-dimensional spacetime (it has been suggested n = 10 or 1...

If energy is an expression of mind that is an easy one; Is it more correct to say mind manipulates energy and therefore matter? Again, mind and energy...

By the way, is how do I type these set symbols? Latex? Is there a guide? Edit: Found it. \in Logic and Philosophy of Mathematics sub forum

Ok, I'll put it this way. List the sets that are not members of themselves as a1, a2, a3, ... X is going to be {a1, a2, a3, ...} But for some i, ai = ...
May 21, 2020 at 10:19
No, I am saying IF X is included in X then X = {{x}, {y}, {z},... {{x}, {y}, {z}}} But IF X is not included X = {{x}, {y}, {z},...} I am only saying t...

Let 'All sets that do not contain themselves as members' be a = {x} b = {y} c = {z} d = ... and these sets go on for as long as is necessary, e, f, g,...

If we define things as follows it might make it clearer- a = {x} b = {y} c = {z} Set X is the set of sets a, b, c so Set X = {{x}, {y}, {z}} If X is i...
May 20, 2020 at 19:33
Yes, but X is a set of sets so X = {{a}, {b}, {c},...} but {a, b, c, ...} might be correct too as long as the logic of what I'm saying holds up. Link:...

It is not 'without X' it is 'without {X}' as a set. {X} is not the same as X, my bad notation in the beginning notwithstanding. X\{X} is every set in ...
May 20, 2020 at 16:46
Yes, you are correct. Since we are talking about sets of sets, a better notation would be- Set X = X\{X} Set X2 = (X U {X})\{X2} Set X3 = (X2 U {X2})\...

No, I am saying there are infinite collections of things that are not a set. See this link https://math.stackexchange.com/questions/24507/why-did-math...

Subset is transitive: If A is a subset of B and B is a subset of C, A is a subset of C. {a} is a subset of {A} and {A} is a subset of {X} ---> {a} is ...
May 19, 2020 at 21:16
{a} is a subset of A and A is a subset of X therefore {a} is a subset of X Also, when it comes to set of sets, {a} can be an element.
May 19, 2020 at 19:43
Ok, change it to 'subset'. Post edited.
May 19, 2020 at 18:56
Set A = {a, w} Set B = {a, x} Set C = {a, y} Set X = the set of sets that have {a} as an subset. Set X = {A, B, C,...} {a} is in X (because {a} is in ...
May 19, 2020 at 18:46
There is no need to redefine the set. All that is needed is to see that there are collections that are not single sets - as the paradox implies. I thi...

Time is often defined as change but this is a weak definition; change is evidence of time but not a definition of it. (Space)time is a geometry accord...

You say there is an object in universe A. But if an object is to exist space must exist and space must be coherent/mathematical. A non mathematical un...

Here is a thought. Write the squares of numbers like this- 1 squared = 1 2 squared = 4 3 squared = 9 etc. Now, you can plot this sequence of squares o...

Suppose we define philosophy as 'knowing the world'. Then a cat is a philosopher because the cat, through consciousness, knows the world. And knows it...

It seems to me that a pure constructionist cannot even admit that there are an infinity of natural numbers. Induction proves that there are and many m...
May 17, 2020 at 17:51
Kummer, Cantor's arch enemy, was a kind of constructionist and denied the reality of real numbers. I guess they just don't agree. The question here is...

Both of them would say that there is an order beyond the physical image. As the hydrogen atom is an image of energy, the physical world is an image of...

The difference is really semantic. Counting is about associating a number with an object; 1 orange, 2 apples etc. But Cantor counts numbers with numbe...

In mathematics infinity is a set, such as Aleph Null, not a process. Infinity is not 'the biggest number' it is all numbers, together.
May 17, 2020 at 11:32
Cantor uses Aleph Null to count infinities. One can count an infinity conceptually, without time. How much time is there between the digits of pi? Lik...

What do you mean by 'thinking'? Abstract 'rational' thinking? Isn't simply being conscious thinking? If thought is energy 'flowing' through the mind t...

I'm not sure about this one. Early philosophy was closely aligned to mysticism (eg Plato's cave). Only in recent centuries did philosophy become heavi...
May 16, 2020 at 18:04
Some argue that there are mathematical or logical tautologies.
May 16, 2020 at 12:47
It is a linguistic tautology (Wittgenstein). In the 'beginning' philosophy was more aligned with mysticism but since Descartes it has become more and ...

Evil cannot exist without good because good is being and evil needs being/God in order to exist. Evil is ultimately self destructive.
January 15, 2020 at 21:48
Good is life an being. Evil is the loss of being. It tends towards nothingness. Evil is not absolute, it must have some being in it if it is to have a...

That would only apply to an evil religion. Hierarchies on the secular world also create great possibilities for evil.

True but that does not tell us anything about the veracity of belief. Personally I am very cautious about psychoanalytic views on religion. They are t...
