The common view of philosophers is that intersubjective knowledge is inevitably unreliable. (Of course in reality there's no such thing as 'intersubjective knowledge').
I wouldn't be so quickly to come to that conclusion. Let us not forget that the vast majority of philosophers have been wrong, in fact, the vast majority must be wrong, as so many hold disparate views that cannot all be right. In contrast, science seems to have gotten things pretty damn close, if not necessarily perfectly right. Newton's laws of thermodynamics and motion still hold today, and even his law of gravity holds up for systems not of excessive mass and not approaching the speed of light. This sort of knowledge by measurement and observation, independently confirmed, has always proven to be more reliable than knowledge attained solely through introspection. Again, this excludes self-knowledge. I am more certain than I am of anything that I believe my name is Adam, and no measurement can demonstrate this.
The same way everyone else does. It's not a problem when it comes to it.
That's pretty vague, Canute. How is it that you and others ensure you are not succumbing to autosuggestion?
It doesn't make any difference what you think or what you're looking for, you end up in same place, something for which there is clear evidence.
Who is you? I would be very surprised to find that every person who has ever meditated or introspected about the nature of reality had come to the same conclusion. If that is the case, why so much debate?
It's not as easy as you think to create a logically consistent model of reality. In fact the non-dual one is the only one I know, and I've looked around. All the rest fall foul of paradoxes and contradictions, Goedel and Zeno, infinite regressions and so on. I'd be gobsmacked if you managed to construct one.
All I'm saying is that it's possible to construct consistent models, even working models, of anything that are still wrong. Look no further than Ptolemy, whose equations for retrograde motion still predict perfectly the positions of heavenly bodies. A model that explains everything, I imagine, would be a little more difficult.
BTW I'm not trying to convert you, just suggesting that it's worth looking into.
Certainly. Everything is worth looking into.
Where do you get your information? I've never heard of any evidence for this view.
You've never heard evidence that only higher mammals and birds are conscious? The information comes largely through intelligence tests and behavioral studies. The test everyone here seems to be enamored with is the reflection-recognition test, but the ones I'm thinking of are problem solving tests. A group of animals, all of the same species, are given a problem to solve, such as a piece of food they must obtain somehow through clever means. One piece of information you get is the problem-solving ability of the animal - if he succeeds, then he is probably more intelligent (it could just be luck, but this is why the tests are performed many times) than the animal that couldn't. The second piece of information pertain to the actual approach. If every animal of a given species approaches the problem in exactly the same way, every time that and other tests are administered, then the conclusion is drawn that these are likely not thinking (or conscious) beings. If, however, one animal of a given species takes a different approach from another animal of the same species, then the conclusion is drawn that those animals are thinking, and hence likely possesses some rudimentary form of consciousness at least (how advanced it is remains up for debate).
I'm sorry that I can't provide you with any links to information about these studies. I've only read about them in journals and textbooks, but if you want a great, detailed introduction to the biology of animal behavior, you might want to pick up the book
Sociobiology by Edward O. Wilson.
Simple. Take that tea you made, for instance. Before you went into the kitchen and opened the cupboard to get it out, it was still there, going about its daily life without you observing it. In fact, had there been an earthquake, it might have fallen out of the cabinet and spilled onto the floor, in a completely predictable manner following a linear causal relationship according to the laws of physics. Heck, take most archaean lifeforms. They are single-celled organism that live in extreme environments not habitable by any other form of life, such as high-salinity evaporation ponds or pressurized water that is well over 100 degrees celsius beneath geysers and hot springs and such. The vast majority of these creatures are never observed by anything, and they themselves are certainly not conscious. Or heck, if you want a more extreme example still, take the surface of the planet Venus. We've never been able to get a probe there; nonetheless, whatever is happening continues to happen without any conscious observer being aware of it.
I suspect that it's unprovable. In fact I'm sure it is. However if consciousness is non-causal, if being conscious does not affect our behaviour, then I'm very good at telling the future. I can predict all sorts of things that eventually I'm going to be caused to do.
It's provable in theory, but the information needed to do so is daunting, and probably excluded by Heisenberg's uncertainty principle. Still, I'm never going to argue that consciousness is non-causal, given the fact, as you point out, that it so very much seems to be. Still, as I've said, I'm rarely too impressed with the way things seem to be.
By the way, I wonder if you are familiar with the Greek philosopher Anaxagoras, one of the early pre-Socratics. He seems to be the first person to ever formulate this theory that the mind is the most basic aspect of reality and brought all other distinctions into existence.
Here's a link to the only piece he ever wrote: http://history.hanover.edu/texts/presoc/anaxagor.htm
In particular, look at fragments 6 and 7.
