Reply to comment by -domi- in Molecular markers of cells involved in the sixth sense — proprioception, the unconscious sense of body position and movement by marketrent
No it only involves touch once your finger reaches your hand.
The sense of touch is not "reach out and touch someone" it's the sensation you feel when someone touches you.
When you reach out to touch your hand without looking the only way that happens is through your body's innate way of detecting the position of your body and all your limbs in 3D space and coordinating the work of many muscles to make that action occur.
That's the sixth sense of proprioception.

I don't think you're understanding what i'm saying. I'm not suggesting there isn't such a thing as proprioception. What i'm saying is that to me, i infer more about my the positions of my limbs from how they touch my other limbs, or my body, than i do from intuitively knowing. Of course there's feedback loops for moving your limbs - no question. That's what makes it easy to know where my limbs are, actually. When i consciously move something somewhere, i might remember where it was. But if i had to tell you right now whether my foot is toed in or out right now, i'd be guessing. I didn't consciously leave my right foot in any particular orientation, and while proprioception should tell me what its alignment is, i'd literally need to look at it or move it to tell you for certain which direction it's pointed.

But when you go to start moving it, it will instinctively align in the right direction to accommodate without you having to look down and go “ok right foot, rotate 18 degrees to the left before moving.”
This isn’t about your conscious knowledge, it’s about your innate subconscious ability to move relatively accurately through space without having to be explicitly aware of where they are and how they’re oriented. If you didn’t have this 6th sense, it would take multiple attempts and/or visual tracking to do something like closing your eyes and touching your nose with your index finger.
Regardless of how you consciously infer limb position, your body generally know where things are and how to move about.

Yeah, I've acknowledged the feedback loop in every comment in this thread.

How are you typing this?

By consciously manipulating my limbs, I've said as much.

Not true, you are consciously thinking "type these words" but your unconscious mind coordinates all the various tendon movements needed to actually make the typing happen.
Your conscious mind is delegating the vast majority of the work to the unconscious mind which uses proprioception heavily to carry out the task.

All of our senses play a big part in the unconscious absorption of the world around us. As with the rest of the senses, each one is connected with many of the others (taste, for example, is a combination of smell and touch, but is also influenced by both sight and sound). Proprioception is intuitively tied to touch, and without touch, the sense is lost.
Think about when you're laying in a recliner. You might cross your legs, or move your arms behind your head, or so on. But no matter what position you're in, the moment you move, your brain already knows where the individual parts need to go without having to input anything. That, specifically, is what proprioception does for us.
Our brains are wired to interpret this information at nearly all times, regardless of whether we're aware of it. I mean, people have actual taste buds on our assholes, but we don't taste it every time we go number 2.
TL;DR:
Our senses are all connected to each other*

Yeah, and like i said - my sixth sense is somewhat stinted, i don't think you've misread what i wrote.

Well, as a bacterial meningitis survivor, my legs have a lot of nerve damage. I have trouble with this sense in them and I never could tell the difference between touch and spatial awareness like I can now. When too idle, it sometimes feels like my legs are asleep. It's an odd feeling to lose a sense you don't even know you have
It's a total game changer, imo

Proprioception isn't about communicating to your conscious mind where your foot is positioned. It's about your cerebellum and CNS working together to coordinate your foot position so it stabilizes you in your current situation without having to consciously think about it.
It's not about you being able to always know where it is but rather trusting that it is keeping you from falling and that you can quickly put it into another position without having to think about it at all.

So, how is it a sense, then?
