AI Thread Summary
Matter can be perceived through touch, but the discussion questions whether this constitutes direct perception. It is argued that all perception is mediated by complex sensory processing, suggesting that we do not perceive anything directly. The only known exception is the direct stimulation of brain tissues, which can create visual experiences without traditional sensory input. This raises the question of what constitutes direct perception and challenges the assumption that matter is uniquely perceivable. Ultimately, the conversation highlights the complexity of sensory experience and perception.

I mean we can touch it and feel it. Can it be perceived directly? I thought it was the one thing that could be perceived directly, unlike energy, gravity, space and time which can't be perceived directly.

In what way is touching it NOT perceiving it directly?
 
Yipes! Don't you know that you perceive nothing directly?

All* perception is the end result of a very long chain of sensory processing mediated by complex connections between nerve cells - all the mind has to work with is a universe of these signals.

* The one known exception is direct stimulation of visual association tissues in the brain from exposure to radiation; astronauts and some others have reported "seeing" flashes of light during some exposures. This radiation is not acting on the retina of the eye, but directly on the cells in the back of the brain that process visual information.
 
I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
