the thing is , is that , I don't look at hydrogen as concept , to start

concept to me is a brain/or mind made thing

hydrogen is NOT a brain/mind made thing or concept

I grasp the idea...but how can you not deal only with the perception and the concept alone ?


because the object dictates what it is by observation and its properties shown by hydrogen

The actuality´s are unknowable´s...still we can state that concepts evolve...


the actuality of hydrogen is knowable by further study

concepts then are based not on reality but on pure immagination

Okay... So you carry things in themselves around in your mind??? Give it a rest.. Concept is clearly a mind/brain thing... Good point... The mind/brain looks for patterns, similarities... The problem is that we cannot see anything until we can conceive of it as some way apart from its background... It is in the conception of things that we see them as objects, and the concept is by no means the thing, but we must define in order to know, and what is defined is conceived...

The last part is not true...what we see is also a construction of the brain if neuroscience is to be considered. (At least partially)

Wrong again.

Two different objects cannot be identical.
If (Fx and ~Fy) then ~(x=y).


So in which way do two separate photons sharing the exact same superposition differ from one another? I fail to see how they do. They would both register the exact same number of bits, and since bits are the utmost basic and fundamental units of information, what information do they not share that dubs them non identical? where is this 'invisible' information that they do not share?

@Soul Brother,

x has the space-time location (a,b,c,d) entails that a different object y does not have the same space-time location (a,b,c,d).
That is, (Fx & ~Fy) is true for the property F ..having the same space-time location, therefore, ~(x=y).

(some F: Fx & ~Fy) => ~(x=y).

What the eyes see without the mind is light and shadow... When you see; what do you see??? Do you think you identify what you see with your eyes???

Well it is true, and you should give it some thought... Look into Schopenhaur and the world as idea stuff... Think of an idea a certain bit of knowledge we can have of the physical world, and how much of that knowledge we get culturally, really, pre-rationally... Perhaps you still remember your first encounter with a four legged animal... Do you remember when you found out, for example: A Dog, was not a Cat, though both had four legs and a tail??? It can get sort of confusing to kids, but also to adults used to thinking as kids think, which is to say unselfconsciously...

The morning light plays softly on some surfaces, and draws stark lines where the shaded sides of objects meets the sunny side... But what would all the objects be that I see without some essential recognition of them???... If you hunt, then you have been in the woods at first light and last, and then as the light waxes and wanes you have seen shapes become familiar with glare, or slip into unfamiliarity in the gathering gloom... Perhaps in your daily life too, you have seen something normally seen in one position, like a photograph, upside down or out of place... What does the mind ask but a question when it does not perceive the expected, and what it has learned to look for???...

I would agree that our conceptions may do fully as much to blind us to reality as allow us to see...Still, there is no way around it... We all learn to see and in the prrocess are given the idea of what we are seeing... If it becomes necessary to see with children's eyes, phenomenologically, with a purpose of greater existential awareness of our lives- which are the root of all perception and understanding, then many of us are at a loss... We cannot let go of reality unless we have a hold of it some where else... Concepts/ideas/forms/notions are our hold on reality...

Hi SB,
Protons don't exist. We apply them to give substance to what we measure.

And not a quibble about the 2 identical things I posted yesterday?

I guess there is your answer mark.

This is something that a person will discover when they're learning to draw. The mind carries a shorthand of images of how things look.... how an egg looks, how a face looks, how a human figure looks. It's funny how when the hand goes to draw, the mind will supersede the field of vision and the hand will draw the mind's image instead. Learning to draw doesn't mean teaching the eye or hand anything... it's becoming aware of how things really look. Otherwise the rendering will look like a stone-age image... easily recognizable to the mind in terms of rational value, as north put it, but obviously not in keeping with what the eye sees. In fact we make a big deal out of points in history when artists learn to create without these mind-shorthands... like ancient greek sculpture and renaissance perspective.

I think north is right. It's meaning that creates the unchanging object that moves through time and space. The unchanging object is an object of thought.

Hi Ken,

Do exscuse my misprint - It should have read "Photons". mea culpa.
It was in reply to Soul-Brother's post.

I have no doubt that protons exist!

Thank you for noticing Ken, and correcting me accordingly.

Kind regards.

Identity is a settled principal in philosophy... And it never has the implication of a complete equality....The word is being misused and the principal is being mis understood... You want me to stand by while all the guppies flounder about
in rhetoric??? Get back in bucket...

Try to understand... If you measure a distance and add or subtract, it has no effect on the concept of length... If you measure pounds and ounces and remove or add to the measure, the concept of weight does not change... Weight is an identity... All weight is weight, and no amount of change of weight changes the identity... Much has been made of leafs in this thread... All leafs are leafs... It is an identity, and no amount of differences between leafs changes the identity of leaf... No one on this earth can produce any like objects in every sense equal... That is not what Identity is about... It is about finding the unchanging characteristics of a thing so that differences can be seen as meaningful...All leafs have characteristics in common...All dogs have characteristics in common... That is the identity, and it in no sense means absolute equality... Let me see if I can make it more clear... One dollar equals 100 pennies... But a dollar will never be 100 pennies, but is in one sense identical to; since each are money... That is the identity, and no amount of money, large or small can change the identity...

Meaning is never found apart from life and mind, with each of these being but moral forms, forms of something immaterial and spiritual as we conceive of all things and non things...

The main issue at debate so far was to my understanding upon the suggestion of a possible equality between any two given things. If we concede that such its not likely to be possible to my view there is no issue to debate further...

Identical objects being similar but not equal is a tautology not worth to be explored.

All identical objects are of the same class, conceived of as the same essential thing, and while the individual elements are various, the class of that identity is conserved... Which is to say that the variety of individual elements does not change the identity, which in any respect allows for variety...

As a principal of logic specifically and philosophy generally, Identity should be known and discussed... The fact is, as Piaget showed, Identity, or Conservation is the stepping stone to all rational understanding... Before the age when children grasp that fact they can only learn by rote, or example, and after they can reason things out for themselves... So, everyone knows it, but most people are not conscious of knowing it... If you expect people to think about thinking they must be made conscious of Identity as a predicate to rational thought...

If one leaf has a raindrop on it and the other doesn't, they're not identical.

If one leaf's contact with an object (a raindrop) makes them non-identical, it follows that, before the raindrop falls, the other leaf's contact with an object (the ground) already makes them non-identical. If they were floating in the air, they would be in contact with non-identical configurations of air molecules. Even if they were suspended in a vacuum, the combination of the earth's, moon's and sun's gravitational pull on them would be very slightly different, depending on their position. The mere presence of other objects is enough to make the leaves non-identical. Two separate but identical leaves could only occur in an otherwise totally empty universe.

Does anyone here disagree with the above? If so, I'd like to know your reasons. (I am using the word "identical" to mean "exactly the same as each other", not merely "of the same class". Let's not get sidetracked by an argument over language.)
