Yes, we will never know the true nature of reality, only our perception of it. Our body-machine perceives the world through its 5 senses. Our brain interprets these signals. Perception is nothing but the interpretation of these signals by the brain.
However, this doesn’t negate the fact that we need a fully functioning brain in order to have these perceptions. So, to all the people claiming we don’t need a physical body with a fully functioning brain in order to be conscious and have thoughts, take a hammer to your brain and smash it in a bit, then see what perceptions you have.
The brain is physical, it is objective, it is us. When the brain dies, we die.
