Sounds like disassociation to me. That trance state is not healthy. It feels good, but it doesn't get you anywhere and plus it reprograms your mind to any suggestions in your external environment. Disassociation eventually leads to derealization. That is the matrix. It's not healthy to get caught up in this web. But, hey...go for it you like. ; ) Maybe a little brainwashing is good every now and then...

Quote:
Derealization (DR) is an alteration in the perception or experience of the external world so that it seems strange or unreal. Other symptoms include feeling as though one's environment is lacking in spontaneity, emotional colouring and depth.[1] It is a dissociative symptom of many conditions, such as psychiatric and neurological disorders, and not a standalone disorder. It is also a transient side effect of acute drug intoxication, sleep deprivation, and stress.

Derealization is a subjective experience of unreality of the outside world, while depersonalization is unreality in one's sense of self. Although most authors currently regard derealization (surroundings) and depersonalization (self) as independent constructs, many do not want to separate derealization from depersonalization.[2] The main reason for this is nosological, because these symptoms often co-occur, but there is another reason of great philosophical importance, namely, that the phenomenological experience of self, others, and world is one continuous whole. Thus, feelings of unreality may blend in and the person may puzzle over deciding whether it is the self or the world that feels unreal to them.

Lol, I'd suppose its not impossible, though I would have to figure that plant consciousness would be a tad different than ours. Boredom for example probably wouldn't be a practical sensation for a plant to have.

A proponent of artificial intelligence recently pointed out that electronic circuitry operates at speeds human neurons cannot hope to match and if robots become sentient they will probably regard organic life in much the way we regard plants. Plants do move and react but at a much slower pace than animals so if they have any thoughts (which I feel is doubtful) their rate of reaction would probably not incur boredom.

Well, the third option is that I am a critic towards consciousness. Some people really are critical towards the idea.

Do you have a subjective personal experience of consciousness?

If so, then being critical towards the idea is delusional; obviously the idea describes something, if you personally have it. If not, then you are a p-zombie.

Now, it's certainly possible to be critical of the idea of a scientific theory that uses consciousness as an explanatory element. However, that's irrelevant to this thread, as it doesn't deny the existence of the subjective personal experience of consciousness, even as only a nonexplanatory epiphenomenon of the brain.


I can be confident that I am conscious but how can I be absolutely sure anyone else is? I take it as a very strong possibility but no more.


This fact is one of many that we can logically suppose to be true without any real evidence.


I do not swallow it whole and assume absolute truth. It is merely a pragmatically useful working tool until something turns up indicating it is defective.


Would you like some more examples of rational beliefs that cannot be justified scientifically:

Logic and math presuppose science and therefor cannot be proven without circular argument.
The belief that the external world is real.
The belief that the past was not created five minutes ago with the appearance of age.
Truly subjective ethics cannot be proven scientifically and presuppose the existence of logic and therefor attempts to prove these things fall into also eternal circular argument.
Aesthetics also cannot be justified scientifically.
Finally, science itself, presupposes itself and in order any explanation would also fall into eternal circular argument.

Technically Sand's position works. It is a very empirically oriented belief. He doesn't require "everything be scientific", but rather the position of pragmatic working tools exists and is defended by some. This idea really tends to exist among the Pragmatists and within Naturalized Epistemology.

It only works if one takes pragmatism to mean assumption.

Well.... no. Pragmatism is a school of philosophy originating in America. It has a focus on "what works", and as such is empirically oriented, and tends to reject the philosophy-first method of inquiry. It doesn't mind having assumptions, recognizing that everyone is bringing assumptions to the table. It has a very anti-philosophical tendency in it, because it is pragmatic.

I stated that they were rationally justifiable. I just said one cannot provide an absolute proof of these things.

You can diddle with angels dancing on pinpoints for the rest of your life but that type of intellectual w*king holds no interest for me. I must function in the world to produce results and do as best I can to foresee consequences. That is all I find necessary. The rest is harebrained posturing.

Emergentism of consciousness doesn't make sense to me either. Panpsychism seems too bizarre, also but here are some interesting quotes/arguments for and against it (see link):

"For example, we say that an electron has a negative charge of about 1.6 x 10-19 coulombs, but what this means is that the electron is disposed to move in such-and-such a way in an electric field of such-and-such a strength. The intrinsic nature of electric charge remains utterly mysterious. And yet it seems reasonable to think that every dispositional property stems from underlying intrinsic properties. Of these, with respect to the fundamental physical constituents of the world, we know absolutely nothing, since physics deals only with the dispositional properties of matter. This is a long standing position. Both Eddington and Russell, among others, agree that ‘science has nothing to say as to the intrinsic nature of the atom’ (Russell called the dispositional properties of matter ‘mathematical properties’). This led Eddington to assert further that we know nothing of atoms which ‘renders it at all incongruous that they should constitute a thinking object’ and to adopt a panpsychist understanding of matter."

"The simplest, and for most quite compelling, argument against panpsychism is that it is intuitively absurd to suggest that electrons, atoms, rocks, planets etc. have minds or any kind of consciousness. Our experience with everyday physical objects gives no hint that they might possess hidden psychological depths. But panpsychism is by no means obliged to grant mind or experience to all such things. As we have seen, even if the fundamental entities that constitute the world (which are physical) have a mentalistic aspect, it does not follow that every composite made from them is similarly endowed."

"But what of the fundamental features themselves? They do not show any very noticeable signs of a mental life. In reply to this, the panpsychist can note that the sort of primitive and extremely simple sort of consciousness which the fundamental entities presumably enjoy is something of which we have little understanding, so it is not clear what would count as revealing their mental aspects. More important, why should we expect that the fundamental entities should show any sign at all of a mental attribute? Gravitation is taken to be a fundamental feature of all physical things and yet we do not expect that an individual electron will provide the slightest evidence that it generates a gravitational field."

What I find interesting in this respect, is let's assume that there is this basic proto-mental/conscious stuff in everything and we come across it at the microworld. What would it "look" like? Some features, I think:

1. Non-locality/spatiality
2. Non-temporality
3. Wholeness

I find it interesting that these aspects are actually suggested in almost all interpretations of quantum mechanics.

If you assume an electron does what it does out of free choice one must assume these little particles are remarkably similar in their motivation and their response to stimulus is without variation. It seems they are not individualists. Since the mass of an electron is known the gravitational field it generates is not a secret.

I find this very interesting. A number of physicists think there is a lot of tension between quantum mechanics and general relativity (quantum gravity). Some feel this difference is unsurmountable.

This is discussed in one of the seven laws of Hermeticism. Consciousness affects subatomic particles. The theory of a universal mind may be true, but if so I still think that we have a choice as to what we focus on. If you sit there and wonder if you are conscious, you are missing the boat. Mental Transmutation is described as the practical application of this principle. To change one's mental state is to change vibration. One may do this by an effort of Will, by means of deliberately "fixing the attention" upon a more desirable state.

Quote:
Mental Transmutation (also described as Mental Alchemy, the Art of Mental Chemistry, and the Art of Polarization) refers to the art of changing and transforming one's own mental states and conditions, as well as influencing those of others. It is also called a form of "Mystic Psychology".

The problem I have with dualism is it assumes that there is a clear difference between "matter" and "mind" but how can one claim there are differences if one doesn't have a clear definition of "matter". How does one define matter? This is Chomsky's argument.

Consider the brain versus the mind. Well the brain is made of neurons, atoms, more basic stuff etc. But ultimately we don't know what this basic stuff/essense of matter is. Physics hasn't ended. One argument is that even with future revision of "matter" we will never be able to reconcile subjectivity/qualia/mental within the material world of a future physics.

Nagel:

Even, if our idea of the physical ever expands to include mental phenomena, it will have to assign them an objective character-whether or not this is done by analyzing them in terms of other phenomena already regarded as physical.

Chomsky:

This argument presupposes some fixed notion of the 'objective world' which excludes subjective experience, but it is hard to see why we should pay any more attention to that notion, whatever it may be, than to one that excludes action at a distance or other exotic ideas that were regarded as untelligible or ridiculous at earlier periods, even by outstanding scientists.

Evidently mental contortionists can be as entertaining as the physical ones.

What do you guys think of this argument:

"For example, one apparently basic property of matter recognized by modern science is the so-called spin angular momentum of certain elementary particles. This property has certain functional analogies with the angular momentum we are familiar with in the behavior of macroscopic objects. For example, the spin of a proton explains its magnetic properties and hence the observed fine splitting of certain spectroscopic lines. But in other respects spin is quite unlike ordinary angular momentum. Only certain discrete values are allowed, for instance, and these values appear no matter what ‘spin axis’ we measure. The point here is that ‘spin’ is defined solely in dispositional terms. What ‘spin’ actually is remains quite mysterious (save for the aura of often misleading meaning drawn from the analogy with the everyday world). Whitehead describes this purely dispositional analysis as a matter of regarding the basic elements of material reality “in abstraction from everything except what concerns their mutual interplay in determining each other’s historical routes of life-history”. This picture leaves the laws of physics as exhausted by “the laws declaring how the entities mutually react amongst themselves”, an impoverished outlook resulting from the way “science has abstracted from what the entities are in themselves”.

Such abstraction is problematic because it is arguable that any disposition must be grounded in some intrinsic nature, and our failure to take this into account leaves us in irredeemable ignorance about the most fundamental features of the world. Whitehead described the predicament thus: “all modern ... cosmologies wrestle with this problem. There is, for their doctrine, a mysterious reality in the background, intrinsically unknowable by any direct intercourse”. Whitehead, following Leibniz in certain respects, asserts both that matter must indeed possess an intrinsic nature, and that there is only one such nature with which we are familiar: experience. Whitehead praises Leibniz, in a phrase reminiscent of Nagel’s worry about consciousness, for explaining “what it must be like to be an atom”.
