To what extent do our senses give us knowledge of the world as it is?

Our sensors receive information from the outside world and this information is translated into electrical signals which are received and used by the brain to create our perception of the world. Our senses enable us to have knowledge about the outside world which is pivotal in survival. The brain is located inside our skull and without touch, taste, smell, sight and hearing we would know nothing about the outside world. However, if we have the receptacles of a senses without the neuro-pathways inside the brain using this information we could not use these senses. For instance, Mike May went blind at age three but he was given working eyes through a stem cell surgery decades later. However, even with the operation being a surgical success May had trouble. “A study published three years after the operation found that the then-49-year-old could see colors, motion and some simple two-dimensional shapes, but was incapable of more complex visual processing” -University of Washington. Jason Webster has said “We suspect that Mike lost vision at an age when these brain regions were able to take on new roles, […] It remains to be seen what these areas are doing now”. Without his brain to decode the information May has very little sight. This means that our senses give us information of the world around us but it is the brain that actually decodes the information and that is what gives us knowledge…
