I know nothing and understand even less! My sensory receptors gather information and my mind interprets that information. It is impossible for me to know anything as all received information has losses and changes through synapses, neurotransmitters, neuro pathways, etc.
My mind "compares" all information according to its own shaded experiences i.e. I see things the way I do because of my upbringing, indoctrination, where I was born, the perception of positive and negative ends to my endeavors, etc.
