Уважаемый Дмитрий! Так как мир бесконечен и бесконечно число его свойств, а наши знания всегда конечны, то отношение знаний к непознанному всегда ноль и ни к какой абсолютной истине мы не стремимся. И поэтому наши знания больше напоминают иллюзию.

Dear Dmitri:

There was a time when the surface of the earth was made up of just the lava (megna) like the surface of the Sun. Today there are so many variety of things on the surface of the earth all made from same lava. When we come across different objects on the earth we react to them in different ways. Not as when we see the molten lava. This is what is called illusion in Indian philosophies. Similarly the entire universe is made up of one fundamental substance. The existence of this fundamental substance is never denied. But this fundamental substance is so subtle that it is impossible for human senses or scientific instruments to detect. Therefore it appears to our senses as empty space. So the empty space is there. You cannot say that it does not exist. When the visible universe returns back to its original state, it becomes the fundamental substance again. This fundamental substance is of the nature of Spirit and consciousness. This fundamental substance is called "Brahm" in Sanskrit. And there is a famous saying of Sankracharya; "Brahm satya jagat mithya" which means Brahm is real and world is unreal. Sankracharya personally verified this before saying it. And it is not easy to verify this. It is much more difficult then discovering Higgs boson.

Dear Podosenov, there are many things we know for sure. 1) Russia won in World War II, isn't it, dear Russian patriot?

Objection: the Existence exists partly: some information about things is true and exists, but the things do not. Information about illusion is not true: "the apple is red, but there is no apple", thus the true information about thing means, that the thing is not illusion. Defense is done.

In science we trust what we can verify through experiments.  But only for so long as the experimental results continue to affirm the hypothesis we are testing.  The parameters of the experiment are derived from the foundations of knowledge inferred from the results of all known prior experiments.  And all else is speculation, and nothing is certain or absolute.

As to Existence, if you believe you may exist then it is better to proceed on that basis than reject the premise as folly and starve yourself to death as a consequence.

Consider this as well.  If you allow for the presence of an omnipresent God who created the universe.  For those living within that universe now, does it really make any difference whether God created an evolving universe some 13.5 billion years ago, or that God created it with a 13.5 billion year history one microsecond ago?  How could they tell the difference?

It is very interesting and intelligent question. Yes, of course, the Existence exists because simply we exist. Everything and everyone firstly depends on their existence properties so without existence there is nothing for me.

Existence we know is in continuous state of change and motion, including human body. There is nothing in the universe which is permanent and everlasting. But there is underlying field which is perfectly motionless which never change and is permanent and everlasting. This is your own self. This is like a 4D motion picture in which everything keeps changing and moving but the underlying white screen is mtionless and without any change. The peculiarity of this 4D motion picture is that the observer has to play the role of a character.

Existence:

"Existence" (in quotes to show a concept) exists in the way that concepts exist, and concepts are not actual components of of actual reality, but descriptions of them.

Existence, as a property that a proposed item may have, is indeed something that an item may have, so the property of existence exists in general and some items may have it. But then we must act, exists according to who, by which I do not mean people. "Does it exist?" is a question that implies that existence is absolute, even though we have now seen that a great many things that have seemed very basic are actually relative to and measured against something else.

To exist would seem to mean being a component of a world of things within which there is some kind of mutual relationships between things, such that within this web, things exist, and outside, they do not.

That is basically the math describing the world- its constraining laws to support a structure.

Next, it would seem that to that math, we can add energy, which is what would make the world and its items actually real (purposely laying aside for a moment that existence is relative, because it turns out the answers would still be the same). Everything real we know has energy; to have zero energy is to not exist. So that leads to the question: is energy an absolute value, or also relative.

From entirely outside a world there is no interaction. And energy is the interaction of elements within the world. And the motions are all within the world.

So next we say, just because outside a world we can't tell there are energetic goings-on, does that mean there are not.

For us to decide that there absolutely is a certain world, there would have to be some absolute, in this case only energy being left in our argument.

It appears that everything that exists, exists only within its own world; otherwise there would have to be absolute energy (and measured against an absolute backdrop), for which there is no proof and no reason to believe in it.

Thus, Existence can and does exist within worlds. Existence exists within our own world. And within it individual items exist. In the special case of being outside all worlds, there is no Existence. Because we are in one, we can verify that having/being in a world is indeed possible. There is not the queer possibility of there being nothing of any kind anywhere at all.

All of this implies that all worlds that can be, equally are (Principle of Fecundity), equally hypothetical and real (making our quantum physics all the more interesting). And it becomes non-mysterious that we find ourselves in one world calibrated just exactly so that it can support humans; there are plenty to choose from.
