@JLNobody,
I was watching a video about the mind and quantum physics. They made the rather simple observation that the brain exists in total darkness. It is encased in our skulls, and can only relate to sensory input that is delivered to it via nerves. In a way we can say that the mind does not contain direct information about the universe, only information about our senses and what they perceive.
And of all the information our senses get bombarded with every second we are consciously aware of only a fraction. Somewhere in the brain it gets winnowed down, and we only perceive what we are able to grasp, based on previous experience, expectation and intuitive capacity. I am reminded of Plato's story of the cave, though in a slightly different way than he himself intended.
