I'm not advocating we distrust our senses as unreliable. I'm saying we have no reason to trust them. My position on this is completely neutral, which is what one would expect when they have no information in either direction. Trusting senses as reliable due to lack of information would be an appeal to ignorance, as would distrusting them due to the same lack of information.
Trouble is, for that to be the case you have to entirely
sensory input - and I've never met a single person who genuinely keeps that open mind in practice. As a philosophical position in a comfy armchair, sure - but once the argument stops, everyone trusts that what they sense is what is actually going on, and responds accordingly. It has to be an all or nothing deal, and for most of us it is. We type our messages to this forum, rather than thinking them hard at the screen, for instance.
That said, I can see exactly what you mean, and I have a lot of sympathy with it. But in practical terms, it all falls apart.
Take for example that I perceive I that I "cut" my "hand" with a "knife". Now....that may be an acurate depiction of reality. It may be that - in reality - the Vl'hurg scientist has stimulated part of my brain in its jar to feel that kind of pain. It may be that my soul has been bitten by the insubstatial Hounds of Tindalos. Or it may be that the universe is out of balance, and as the caretaker it has informed me of that and requries me to rebalance the universe by applying a bandage.
Reality could be all those things. But I know that if I slash what I perceive to be a sharp knife across my hand, I will feel pain, and see a wound, and bleed.
Similarly with every other aspect of my life: if I feel "hunger", I know that "eating food" will remove the sensation. I watch films. I read books. I know that boarding what I perceive to be an aircraft will result in my soon perceiving myself to be in a foreign country. Everything I perceive, and every way I react, leads to consistent and predictable results, so for all practical purposes, what I experience is what "really is".
I understand that for the severely mentally ill, what they perceive is not what really is (at least so far as us disinterested observers would hold it to be), so we have precedent that senses do not necessarily correctly interpret reality. Yet even then, their view is internally consistent, as they see it. They experience better days if they count to 100 in 4s when they awake, so even then they can "rely" on their senses.
I think that's the bottom line for me. Reality could be anything at all. But when I ignore my senses and try to act as if reality were different to the world they present to me, it doesn't work.
Reality COULD be entirely different to what we perceive. But as I've said before - if we have no way of detecting that "real" reality, and if everything we experience supports (and impacts on us) as if the sensory perceived reality is real……does it matter?
And perhaps more importantly, given there is apparently no way we can detect or determine this "real" reality anyway…..what makes us decide to question our senses in the first place?
