For example, let's take the water. In a situation where the temperature is between zero and one hundred we have  water (I can feel them cold or hot flowing or non-flowing), below zero they become ice (I can feel it as hot or cold, hard or softer), and when heated they disappear and become For gas that we do not have the ability to perceive in the five senses.

is it  possible to say what the water itself is regardless of how our senses perceive it?
Or can it actually be said that we have no attainment in essence?

Well, water is water, regardless of its phase.

Or can it actually be said that we have no attainment in essence?

I think there may be a language barrier here, but I'm not sure what you mean by "attainment in essence".

[alancalverd]

Water is H2O. Like most other substances it exists in at least three phases, and the interaction of squidgy stuff like humans with solids, liquids and gases is dependent on their thermal and mechanical properties. That's science, and it's useful and important. Philosophy is just a waste of life.

i don't know exactly what do you mean?

[yovav (OP)]

Well, water is water, regardless of its phase.

I will try to explain. Suppose you and another creature look at a table.
You see the table is brown. You touch him and he is hard and cold.
The other creature has no sense of sight or touch. Or experience the table through the smell and electrical pulses.
If they both explain to someone else what the table is they will describe two completely different things.
It follows that the table is nothing but a result of the same receptors that receive it.
What is it in itself? What is it regardless of who catches it? This question concerns the essence. That I claim we have no perception of it.

I completely agree that philosophy is a waste of time. And precisely in order not to become philosophers we must delve deeper into understanding the perception of reality.
The same water that is made of oxygen and hydrogen, the same water that is felt cold, hot, once ice and once gases.
I argue that they are a total admiration of the way my senses perceive water.
I understand it's hard to absorb but your world is not the other's world. Certainly not of other creatures with other senses.
The same water, like other substances, is the result of two things:
1. Our senses
2. Something external that I can say nothing about until the moment it comes to my senses.

[yovav (OP)]

i don't know exactly what do you mean?

Did the ultraviolet and infrared exist before we discovered them?
And now that we've found a device that has revealed something to us, do we know what they are or how those devices we built give us an interpretation of a particular phenomenon?

[Petrochemicals]

For gas that we do not have the ability to perceive in the five senses.

Steam you can sense, you can burn yourself on a kettle, just as any gas with a high enough pressure and temperature

[yovav (OP)]

Steam you can sense, you can burn yourself on a kettle, just as any gas with a high enough pressure and temperature

Okay, and once it's gone, PPOOF, you can no longer feel it...

[alancalverd]

The same water, like other substances, is the result of two things:
1. Our senses
2. Something external that I can say nothing about until the moment it comes to my senses.

That's where you dive off into philosophy and risk drowning in your own pointlessness! 

Science begins with the axiom that water is water, and it interacts with different things differently. Thus we can distinguish between a polyethylene and a polyethylene terephthalate insulator, as I once had to do, by whether it floats in water.

The idea of keeping one element constant (e.g. water, or an elephant) is rather fundamental to scientific experiment. Pretending that reality depends on the observer is madness. 

[Petrochemicals]

Steam you can sense, you can burn yourself on a kettle, just as any gas with a high enough pressure and temperature

Because its not there? Pretty much like anything else.

[Origin]

You see the table is brown. You touch him and he is hard and cold.
The other creature has no sense of sight or touch. Or experience the table through the smell and electrical pulses.
If they both explain to someone else what the table is they will describe two completely different things.
It follows that the table is nothing but a result of the same receptors that receive it.
What is it in itself? What is it regardless of who catches it? This question concerns the essence. That I claim we have no perception of it.

First you say we perceive the table and then you conclude that we can't perceive table.  I think your conclusion should have been we have a limited perception of the table.  I think this trivially obvious.  We can only perceive a limited frequency of the photons coming from the table, we cannot sense the protons, neutrons or electrons in the table.  We can't sense the strong force or weak force in the atoms.  It goes on and on what we can't sense in the world around us.  Like I said, this is trivially obvious.

[alancalverd]

The problem with the philosophical nonconcept of essence is a lack of definition. Is the essence of a table
wood
color
quadrupedia
mass
height
workmanship
utility
or any other quality that distinguishes it from a fish?

Until you have defined "essence", you can't claim not to be able to sense or understand it. Oddly, a good patent agent probably gets closer to defining the essence of things than most people, since for the purposes  of generality in a patent application a table is "a suitably rigid horizontal surface supported by a multiplicity of vertical and/or diagonal struts" 

[yovav (OP)]

That's where you dive off into philosophy and risk drowning in your own pointlessness! 

No!
This is where I set the boundaries of science.

[yovav (OP)]

Depends on how you define 'exists', but that's a philosophical distinction, and you have no interest in philosophy.

True, I tend to agree.

[yovav (OP)]

The thing you want is not called 'essence', but rather the 'thing in itself', or 'ding an sich'

You can call him by any name. The main thing is that you managed to understand my claim. In any case it has nothing to do with philosophy but rather to strengthen the definition of science.
 

[yovav (OP)]

Until you have defined "essence", you can't claim not to be able to sense or understand it.

I will try to define the essence: the form in which the same element / substance / body etc. exists regardless of the same senses that perceive it.

[Bored chemist]

As far as I can tell, the essence of a table is its purpose- you can put stuff on it.
There is no way to deduce that from the material it is made from, or its size or whatever.

[alancalverd]

I think that the essence of A  is whatever distinguishes it from B.

[yovav (OP)]

I think that the essence of A  is whatever distinguishes it from B.

Again my intention in essence: the initial state of some object, regardless of the form we perceive it in our senses.
