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

What we do with our senses differs from person to person, depending on their needs and abilities. People depend on their senses and the knowledge it provides them with in order to survive given circumstances.

Because such people only have one cortex, unlike normal people who have a division of two sections, they miss certain brain functions which would normally trigger emotions or reason. Their single cortex however, enables them to use their memory as efficiently as possible, reaching up to 98%!

Their disadvantage is that what they memorize is no use to them. They store it in their brain, until new information is memorized; slowly causing old memory to simply be forgotten, therefore, in such cases, knowledge for perceiving the world around them is really only at a very low level.

Plato, an ancient Greek philosopher, once said that revealing our senses to perceive the world around us will never happen, rather we would only gain a poor copy of it. Personally, I agree.

We cannot perceive and understand everything around us, we can only interpret things in a certain ...
